Applying to Y Combinator: What You Need to Know

Being a Y Combinator founder is a dream for many aspiring entrepreneurs. If you’re considering applying to Y Combinator, this blog is for you. In this blog, we will discuss the key factors that Y Combinator looks for in founders and how to increase your chances of getting accepted.

1. Strong Founding Team

Y Combinator values sharp, strong founders who can execute their vision. While having a product is not mandatory, a solid founding team is crucial. Founders with determination, fortitude, and the ability to take action are highly sought after. These qualities are essential for building a successful startup.

2. Cohesive Founding Team

Y Combinator also looks for stability and cohesiveness in a founding team. It’s important to have a team that can work well together and handle the stress that comes with building a startup. Long-standing friendships or relationships built on trust and respect can be advantageous in this regard.

3. Technical Expertise

Y Combinator tends to favor founders with technical expertise. Whether it’s building applications with a user base or working on complex projects in a specific industry, having a strong technical background can significantly increase your chances of acceptance.

4. Market Size and Idea

While the idea itself is not the sole determinant, Y Combinator does consider the market size and potential of your idea. It’s important to articulate your vision concisely, highlighting the market opportunity and how your product or service fills a gap.

5. Excellent Communication Skills

Being able to articulate complex ideas in a clear and concise manner is highly valued by Y Combinator. You need to communicate the most important aspects of your idea effectively, both in your application and potential interview.

6. Preparation for the Interview

If you’re selected for a 10-minute interview, preparation is key. Invest in good video and audio equipment to ensure clear communication. Slow down your speech and be concise. Avoid talking over each other if you have co-founders present. Make sure to have a clear division of labor and highlight each member’s expertise.

During the interview, focus on key points, such as your team, the problem you’re solving, the market size, and any traction you’ve gained. Be passionate and make the partners excited about your vision.

7. Use Alumni Network

Reach out to Y Combinator alumni for advice and insights. The alumni network is vast, and many founders are willing to share their experiences. However, remember to gather advice from multiple sources to gain different perspectives.

8. Be Confident

Confidence plays a significant role in your pitch. Practice your pitch repeatedly, record yourself, and refine it. Be ready to answer any questions thrown at you by the Y Combinator partners.

Remember, getting into Y Combinator is a competitive process, but with the right team, preparation, and passion, you can increase your chances of acceptance. Good luck with your application and potential interview!

I have written a bit more about how to get into Y Combinator several years ago as well, you can find that post here.

Executive Coaching, A Secret Weapon
Rock Health Digital Health CEO Summit, A Few Years Ago

When running my last startup, the first time I ever considered getting executive coaching for myself and my team was at the Rock Health Digital Health CEO Summit, I saw one of the panelists talking about hiring an executive coach for themselves and for their team. Up until that point, I had been building my start-up without executive coaching. I realized we needed a bench of amazing coaches, thinking that getting executive coaching for the executive team and me would be something that would help facilitate, keep the team on the same page, and help my startup grow.

Football teams, the Olympics teams, soccer teams, boxing/UFC fighters, and basketball teams have coaches, why not your start-up? The best CEOs and founding teams get help and advice from advisors, board members, their team, and their customers; having a coach is another support system most founders don’t think of. Even the best of the best teams in the business world add executive coaching to help the founders. For example, Apple’s founder Steve Jobs, former executive chairman and CEO of Google Eric Schmidt, and Facebook CEO Sheryl Sandberg worked with Bill Campbell, the million-dollar coach. Being a founder can be a long and lonely path so having a coach to run ideas, strategy, and short and long-term incentives and concepts is amazingly valuable.

The band Metallica has been around for decades; in the movie “Metallica: Some Kind of Monster” the band was insightful and hired a coach Phil Towle to help keep the band together since they lost their bass player Jason Newstead and the band was falling apart, an executive coach fits a need in that same way helping a person grow in their career.

My co-founder Michael and I a few years ago started to dig and look for executive coaching teams and realized it was hard at first to find a good team. After interviewing several coaching teams, I started to understand the coaching community; there is a big market out there for executive coaching. There’s a large amount of amazing talent out there to help you grow and help your team. 

Founders of InnerSpace

The first experience I had was with a Y Combinator company called Innerspace, a wisdom community for startup founders. Innerspace was founded by Semira Rahemtulla and Joe Greenstein, who held free sessions for founders in San Francisco; it was an amazing experience to go to these events and see top-tier Exec Coaches that were presenting and helping founders.

Kim Scott, Executive Coach

Several founders, leaders, and company executives approached me about executive coaching and how that might work. Like any relationship, it must work for the person getting coaching and for the coach. What I did throughout the years was interviewed several coaches; I highly recommend interviewing around five executive coaches to see if there might be a fit. Getting a coach is very similar to hiring a psychologist, you must see what is out there and see what might work for you, seeing if you might fit with their personality, the way they work, and the dynamics between you both to really get an idea of how they can help you. I bucket some Executive Coaches amazing for company offsites, others are amazing at running retreats, others are amazing for 1-1 coaching, and others for doing a one-time session on a focus topic. You can always try before you commit; maybe do a month of sessions to see how things go and check in to see if the coaching is working. Scaling yourself and getting the growth that you need is so important to see what best fits you and your team’s needs, but offsite with an executive coach to see if they can work well with you and possibly with your team. If there are several cofounders, you can even create strategies to align the founders by getting the same executive coach to work with all of the founders on a monthly basis, it depends on you you’re co-founders and your team’s needs on how you want to pick and use your executive coach again they’re there is a resource and a sounding board for you so really you’re in the driver seat to see if they’re giving you the advice that helps you bring your company and your startup to the next level.

Investors at times can also give Executive Coaching advice from time to time, but I found few founders that look outside to get that executive coaching expertise.

Sometimes executive coaching can be expensive. If you want to work with a coach, find a coach who is in your budget range, but you can always ask if the company is short on cash, offer advisor shares, or defer payments to a future date, maybe at the next funding event.

This is a list of a bunch of possible executive coaches. I highly recommend the list of people below.

I can’t say enough good things about this executive coaching team if you are looking to talk with them. You can find the founders here.

Peter Hill

Peter is an amazing talent who can help, he can be found here.

Joe Greenstein

Joe can be found here.

Semira Rahemtulla

Semira is an amazing executive coach who does it all and can help, she can be found here.

Ed Batista

Ed is an executive coach who I did a session with, he is amazing if you can get him; sign up for his blog and newsletter; he is insightful.

Kim Scott

Kim wrote several famous books, Radical Candor and Just Work. Kim and her team do coaching sessions, you can sign up for them here.

Michael Terrell

Michael is another coach that amazing and should be considered, he has a podcast and book, and this is his website.

Larissa Conte

Larissa is another coach with who I have taken a session who is amazing, this is her LinkedIn.

Kate Roeske-Zummer

Kate’s website is, she also has a book.

Caroline Webb

Caroline wrote a book, “How to have a good day” and does coaching,

Wendy Bittner

Wendy is a partner at Cultivating Leadership.

Jerry Colonna founder of

The team does 1-1 sessions, retreat/boot camps, and has an amazing podcast.

Mark Voorsanger

Mark, CPCC is from Skyward Coaching, his website can be found here.

It is important to recognize that building a company is hard and growing as a founder is a must if you want your company to succeed. It is hard enough since most companies fail. It is better to have a team and sounding boards to help you make sure you are on the right course.

Life Coaching vs Executive Coaching

I’ll end with one other branch of coaching, which is life coaching; life coaching is similar to executive coaching, but life coaching primarily examines who you are and how that way of being translates into your actions and results. Executive coaching focuses primarily on what you do and what you have, with a secondary focus on who you are, while analyzing what you do/didn’t do to get the results achieved so far.

One amazing coach I recommend is Arda Ozdemir. Arda runs the coaching team Rize to Realize. I highly recommend his book. Below is a great video of a part of what life coaching is about.

Support is important for growth and for becoming the best leader possible. I’ll leave you with this last video from Y Combinator, which is also an important topic when building companies –

Leaders. Accounting. Finance. Modeling.

You should understand what your CEO, COO, and CFO are talking about.

An MBA can cost as much as $200,000 dollars, below are a few great resources for anyone who wants to learn about the financial aspects of running a company.

The basics are the most critical aspects for anyone who wants to learn, the Financial Story Teller is one of the best educators about finance.

This course “Introduction to Finance, Accounting, Modeling and Valuation” is well worth the money.

Perhaps one of the best videos on SaaS if you are running a Software as a Service company is from David Skok of Matrix Partners: Driving SaaS Success Using Key Metrics

Enterprise Value vs Equity Value

Enterprise value (EV) and equity value/market value (MV) are business valuations. Enterprise value (EV) is used when considering the purchase of a business, whereas equity value/market value (MV), is used when considering an investment in the common stock of the business. A great resource for reviewing these valuations definitions.

Enterprise Value

The net assets of a business are funded by a combination of debt and equity. It follows that the value placed on these net assets must be the same as the value placed on the equity plus the value placed on the debt.

Net assets value = Equity value + Debt value

Top 5 Healthcare Tech Predictions for 2021 in a Post-COVID World

The coronavirus pandemic jumpstarted the digital health tech market with solutions that bring a stronger connection between patients and doctors. More physicians are turning to new innovations that can improve the patient experience and raise the level of care necessary as we navigate these new times. Here’s my take on what’s ahead in health tech in 2021 and beyond.

Remote Patient Monitoring (RPM)

RPM is going to be a big part of our future due to COVID-19. RPM tools allow physicians and medical professionals to remotely monitor patients in real-time tracking a patient’s well-being. Medicare and Medicaid as well as other insurance companies are now receiving reimbursement for RPM. Additionally, Internet-connected blood pressure cuffs, scales, and the like can be used for RPM. IoT devices are also part of the RPM future, such as IoT glucose meters for diabetic patients, IoT thermometers, and sleep monitoring devices. By adding RPM from providers such as KeepWell,100Plus, and MD Revolution, practices can focus on patient care and have access to real-time patient data and remote staff support. With more physicians turning to virtual care, telehealth and EHRs that manage this critical patient data are proving to be the lifelines to modern healthcare going forward.

Telehealth & Telemedicine

Telehealth visits are going to supersede in-person visits as time goes on. Because of COVID-19, the world changed and Medicare and Medicaid, as well as other insurers, started paying out for telehealth visits. Telemedicine will continue to grow at a very quick rate, and verticals like mental health (psychology and psychiatry) and primary care fit perfectly into the telemedicine model, for tasks like administering prescription refills (ePrescribing) and ordering labs. Hyperlocal medical care will also move towards more of a telemedicine care team experience. Patients that are homebound families with young children or people that just recently had surgery can now get instant care when they need it. Location is less relevant because patients can see a provider from anywhere. 

Machine Learning

Machine learning will become an even bigger part of healthcare in 2021. For example, machine learning combined with telemedicine will give more insight to a physician in a remote setting reading voice intonation and facial expressions for a patient’s mood, pain, or depressional flags and the like. ML will be able to indicate and provide mood data to the physician in real-time and will allow the doctor to take any immediate action. ML-powered medical copilot scribing can help write a draft chart as the patient and doctor chat via telehealth. A lot of information is exchanged quickly, and having a real-time scribe will save time for the medical community. Companies like Diagnoss ML Medical Coding Assistant are partnering to provide ML-based scribe services. There’s also ML for early diagnosis, for example during a telemedicine appointment if a patient has a consistent cough or drop/change in tone of voice is detected, this can also be flagged to the provider to ask more questions to a patient. Practices can accelerate their business during the pandemic and integrate solutions like Holly by This virtual assistant is vastly improving a practice’s operations and efficiencies by managing inbound and outbound scheduling calls, telehealth workflows, reducing no shows, and filling canceled slots.

Mobile Health

Apple rolled out a series of new products and features over the past few months that will greatly impact healthcare and bring more benefits to physicians and patients. Apple is one of many players in the industry making the investment and committed to bringing the latest innovations to healthcare. Here are just a few of Apple’s exciting announcements:

  • Apple’s new Blood Oxygen sensor in the Apple Watch Series 6 can change the way consumers monitor their health. 
  • The new iPad Air features more power and functionality such as an all-screen display, a smaller Touch ID sensor, new cameras, and a redesigned speaker system that will help medical staff expedite log-ins, run apps more efficiently, and review X-rays and other images. 
  • Picture in Picture is new allowing a provider to watch medical videos while multitasking.
  • HomePod mini can read off reminders and texts to a medical professional from home.
  • iPhone 12 now has 5G with improved performance and speed. The Phone 12 Pro video camera enables providers better than ever medical video. Also, when complex medical scans need to be reviewed, this new technology can allow physicians the ability to download images faster than ever and could be lifesaving.

The Pop-Up Testing Clinic

COVID-19 has ushered in a new way of testing that has never been seen before across the country. The white tents scattered around parking lots and connected to medical facilities have proven that this new way of testing is working. Furthermore, the data that is being collected, stored, and reported at the pop-up testing clinics and then shared with various local, state, and federal public health databases is critical. Companies are creating integration tools to help share and analyze this data.

If you haven’t already, take a look at some of these new developments in digital health tech to see how they can improve your practice and ultimately enhance the patient experience. Take the time to research and determine the solutions and partners that are the best fit for your practice and patients’ needs.

Life in Balance

Daniel Kivatinos, COO and Cofounder of DrChrono

It’s what you practice in private that you will be rewarded for in public.

Time is short and running a company takes an enormous amount of focus, having a family and maintaining friendships is an important part of being a whole person. Shawn Stevenson talks about relationships correlating directly to your health, if you have good relationships, your health dramatically improves. In life one of the most important things is our health, be sure to make it a priority.

I hear people saying the words “work-life balance,” are important, I once heard someone talk about “work-life integration”, which is a better way to think about work and life. Why? If you can integrate your working life and home life, you can maintain the pressures of work and the needs of family and friends for a longer period. Life isn’t a quick race, startups aren’t a quick race, startups take time, so thinking about building a startup is like planning to run across the country, what is the easiest, smartest route you can take without falling apart along the way.

Below are some insights, ideas, and thoughts on how to have more life in balance.


According to the U.S. Census Bureau, the nationwide average spent driving one-way commute to work is about 25.5 minutes, with Americans spending more than 100 hours a year commuting. Think about leveraging that time always for something productive, I always capitalize on that time. If I’m driving, I ask myself what can I do to be making an impact today? Or is there something I should be learning, or someone who I can call on this trip. The car and commute time is a great time to capitalize on a phone call or learning, listening to an audiobook.


Having a support system and social life outside of work is important, whether it be a sports team, a board game meetup, a Pokemon Go group, be sure to find a group of people you can connect with. For my family, we are part of the local YMCA, they provide members “instant social events,” where I can take my son and have a great time. My son joined the local basketball team, it helped us both get out and about without the need to plan events, they provide great resources. I highly recommend checking out the Y.


I spend about two-thirds of my time on my business and about one-third of the time networking. If I didn’t network a part of my time, DrChrono would have never have gotten in Y Combinator, we wouldn’t have found our enterprise sales leader at Stanford or found our first designer Hong. I focus on my strengths and find others who can fill my gaps.

Choose your peer group really well. The number one way to improve or play at a high level is to populate your working life with high performers.

I connect with people at least once a week that help me grow personally or professionally.

I have several people that I consider my “accountability partners’ who keep me on track and push me in areas of business and personal life that really keep me accountable. 


Always have walking meetings, at DrChrono part of our company culture and to have good team communication, we tend to go on a lot of walks. Strategy walks are always productive giving, getting updates and learning from my team.

In the early days even before we incorporated back in 2008, Michael and I would go on lengthy walks to talk about action items we needed to take to build a company in healthcare. We both knew creating a lasting company in the healthcare space would be a long-term endeavor. 

Communicating rapidly every step of the way would be critical. We would stroll to local coffee shops in New York City, talk along the way, grab a coffee, talk some more and walk around the city. Walking also paid off in finding some critical team members. A great example: We hired Hong our design leader simply by going on walks with him. Hong and I knew each other as friends. I would tell Hong a bit about what Michael and I were working on and he would give me input on design, we did this a bit and those walks led to him joining us early on. 

Walking made us more productive. We would go for a walk, get our legs moving, blood would be flowing and get our minds in a good headspace where we would think clearly about the company. We have been doing this since the beginning of the company.

The same goes for phone calls, one of the best ways to stay in shape, be mentally healthy is to simply get up and walk around. Get a standing desk as well as your draft and send out emails. The human body wasn’t designed to sit for long periods of time, humans were designed to hunt way back when.


If you don’t make time for health now you will be forced into illness later, the most important thing in life is to have enough energy to tackle the problems of a day, if I don’t have enough energy I won’t perform well. I educate myself on what keeps me healthy on a weekly basis, learning from books and podcasts. For example, does water help in the mornings? Nothing tastes as good as feeling healthy.

Some tools for health that I use:

TRX Tactical is great for travel – One great way to stay in shape is TRX it’s mobile keeps you healthy and you could bring it anywhere traveling at work anywhere.

Resistance Bands are also great for travel – Another great way to stay in shape is resistance bands there actually really mobile you can throw them in your backpack. 

Small Home Gym – One secret to staying healthy long term is to make a small investment in a small home gym. You don’t need anything big but a few items to really allow me to get a quick workout in on the days I simply don’t have time to go to the gym. You can buy a small weight set and kettlebells at Costo or Target for home.

Health Apps I recommend and use:

  • Headspace and Insight Timer – A must for stress management – a meditation app.
  • Lose It! – I use it to track how I am doing with my general health.


Spark your mind daily, be careful what you let into your mind. I am trying to create sustainable greatness and focusing on my family and my business for the long term I really think about stayings invested in the long term payoff. I am playing a 10-year game, not the 6-month game so looking at things long term helps me. I believe that preparation and getting in the right state of mind allows me to put the best me out there. 

Motivation Apps I recommend and use:

  • Peptalk – I use this app to really set my mindset
  • Motivate – an alternative to Peptalk, just as good for the mindset


My commute is important to me, since time is everything, having a short commute makes a world of difference. I used to have a job where I worked from home and at the other extreme, I had a job where I committed several hours a day. It was really the long commuting hours job that was hard. Having a short commute makes my life way better, I can hop in the car and be at work somewhat fast.

I make sure to spend time with my son and my wife I generally drop my son off at school every day making sure I have that small bit of time in the morning making sure I am there for him. Being a good dad is important to me.


Highest value things are done when I have good “brainpower.” Throughout the day I have different times where I get a lot of work done. Here’s what I find helps me the most:

  • Morning routine
  • Set intentions and get priorities straight
  • Mornings are coveted focus time for me. I generally wake up after 6-8 hours of sleep a night, do a workout to prime myself for the day ahead. Have a glass of water and then try to figure out what will have the most impact. List out up to three things that if you accomplish them, you have made a big impact. 
  • Your priming morning – first 60 minutes is most important. Really focus on important meetings, hard tasks and things that need to be pushed forward, i.e. important initiatives.
  • Then the highest value thing should be tackled first – the profit that produces results – 60 minutes no interruptions.
  • 20 minutes – do something else like going for a walk around the block
  • Making time for creative thinking, for me, is sometimes at night and sometimes in the mornings, and the weekends but keeping times for this is critical.

I always create bubbles of focus, having times or days where I focus on a task. I have my “Menlo Labs” like what Thomas Edison has, a place to totally focus and an offline distraction-free, it is important to get a deep focus on one task per day.

I do like to change up my environment, I tend to work in various conference rooms at the office, I sometimes take an Uber and work in a different location, i.e. Starbucks is a great place to work for a change of environment.

You can always create more money but you can’t create more time, ”seize each day.” Remember that. 

My three key areas are:

  • Taking time for personal development
  • Taking time for thinking strategy 
  • Taking time for action and execution

Maximize every second of the day 

  • Have training team time
  • Stay fully present while focusing on your time 

I tend to focus on what I want (the outcome), not always tasks and everything I need to do all of the time which has allowed me to really build a company over 10 years. Here are some of my other suggestions for making the most of a productive day that has worked well for me over the years:

  • Be unorthodox and be unreachable at certain times to do deep focused work 
  • Have a schedule that works for you 
  • Get gas when no one else does, get your groceries when no one else does 
  • Lines can kill your day suck time 
  • Teach people how I wanted to be comminuted with, e.g. calendly & slack
  • Check email at specific times 
  • Whatever you focus on multiplies 
  • Time block on specific tasks
  • Spend time on profit-producing activities 
  • Have a perspective you only have 24 hours
  • Don’t say “I have tomorrow”
  • Identify my highest four times – when do you get the best results 
  • Figure out when you have the best focus, not when society says you need to do this task at x time.
  • Always remember habits define me

Some additional strategies that I use:

  • Think 3 or 4 steps ahead of the business 
  • Stress is not your enemy. Focus on getting results and it reduces stress
  • Change your environment to change your stress 
  • Shift my perspective 
  • If you have a problem try to come up with two solutions 
  • Analyze why I am stressed 
  • Weekly master plan – work on planning out your week for an hour – a powerful purposeful intention 
  • Always have a deadline 
  • Celebrating weekly progress
  • Quick celebration and quick recover 
  • Train your mind like a muscle, and not multitasking – do one thing to completion 


Since I have my phone with me I have several critical apps I use. Here are some:


  • Evernote – I use this app as a general note-taking app for any meeting, it runs on any device.
  • AirTable – A great databasing app, great to track lists of investors, business dev
  • Calendly – helps me scale and allows people to find times on my calendar that work for them,
  • Trello – An amazing project/task tracker.
  • Apple Notes – I use Apple notes for lists. 
  • Todoist – I use this app to track talking points for 1-1s
  • Things – A general task app.

Become an expert on what apps are out there for task tracking and pick one. Education is also very important. I view learning as a lifelong endeavor. Books, audio and videos to spark my mind.

MOOGs are really taking off and there are a few that I use all of the time to sharpen my skills –

  • Audible – A must for everyone who wants to listen to an audiobook on the go. I use it when I am doing laundry.
  • CreativeLive while cooking on the weekends, I am always learning something new from the ever streaming masterclass courses that are happening. The Apple TV app is great.
  • Udemy is great for learning anyplace, I generally am going through a course a month to sharpen my skills in business.


Schedule a few vacations, book them now, I have been booking vacations far out, I book them and don’t wait. Having a vacation booked sets a precedent that you have slotted time off, the act of booking the time off will allow you to have some future time to look forward to. I sometimes don’t book anything too extravagant, maybe some time with family where we go drive to a hotel for a week.

Building on the drchrono iOS API through Deep Linking

What is deep linking on iOS?

Deep linking in iOS is using hyperlink URLs to launch an app with specific content. The specific content can be a particular section of an app page, or a certain tab or specific view. To test this out you can download the Twitter app, login and then close the twitter app. Next open twitter://timeline in your Safari mobile iOS browser and wallah, iOS will switch to the Twitter app and go directly to your timeline. You can even do more sophisticated app switching like this – in your, iOS Safari Browser enter this, twitter://post?message=learn%20deep%20linking and the native twitter app should open up with a draft message composed “learn deep linking”.

You can use deep linking for:

  • Moving data between the apps from launching an app from another app and passing information
  • Building a web-like URI based navigation scheme within your app
  • And of course integration with other apps like drchrono EHR by letting them launch your app directly
  • Also recording and reviewing user behavior to learn where your users launch your app from

How to use deep linking on Apple iOS iPad?

To link back into drchrono, it can now be done, you can Deep Link into the iPad iOS appointment page. This is the code to do it, it is super simple to do –

 Deep link to an appointment drchrono://appointment/<appointment_id>

You can Deep Link into the iPad iOS patient chart as well –

Deep link to a patient drchrono://patient/<patient_id>
You can Deep Link A great example of a partner show has built into drchrono is our partner Physitrack

How to Login to EHR via oAuth?

If you wanted to setup login on iOS, it can be done, the team at Eko Devices did an amazing job. They leveraged the drchrono Healthcare Doctor API which can be found here,

You can see a video here –


Building on Fast Healthcare Interoperability Resources / FHIR


We started drchrono leveraging technology; our mission: to build something physicians and patients want, tackling hard problems and to fix healthcare.
As part of our mission and as the healthcare revolution is also happening we want to enable an open API for developers from around the world to work together. We see a future where physicians and patients can use wearables, Internet of Things (IoT) devices, other medical software and hardware to leverage our cloud-based EHR and API. Healthcare should not be siloed where data is locked into a non-cloud-based EHR. In that future developers will come together to build jointly to create a better healthcare experience for everyone, providers, patients, caretakers, and family.


The Argonaut project is a way to make healthcare more interoperability, drchrono is a part of this project. The idea is to get different players in the industry on to a simple to understand easy interface. (drchrono has also committed to Sync For Science)

There is a new data standard called FHIR or Fast Healthcare Interoperability Resources.

There are some core objects or classes called “resources” that show how we represent different pieces of data in health care. Things like what is a patient look like, what does a medication look like and what does an allergy look like.

In healthcare we are always asking, how do you package data, so things like patients, they have a first name, last name, date of birth, phone number, address.

EHRs are storing patient data in different ways and it looks totally different. But if we standardize the interfaces for transferring and for receiving, the can make sure all of these different systems can communicate when sending data back and forth in an easy way. Healthcare is been transferring data for years either by hand or electronically. This is important now because we have been transferring data through on scalable standards like HL7 version 2 and X12s format. X12 and HL7 formats are delimited file formats that have embedded information with a hierarchy to that data, but it does not pass it attribute names with it. So what that means is both parties beforehand have to agree and know exactly in the format and order of the data before transfer, explicitly knowing this information before e.g. Knowing names and the delimiters in great detail. This only allows them to develop for each other using those formats.

On the other Modern formats such as JSON and XML are using a lot in web development. They are agreed on apone standards that developers can all use that tag patient information so what you call a resource you know what you are calling.


drchrono just launched a version of the FHIR API for the 10 million patients on the drchrono platform. The personal health record platform called onpatient has the FHIR API documented here –

  • Build an OAuth Login and Logout
  • Build a way to view all patient information that is available via FHIR.
  • Build a blood pressure tracker
  • Build a sleep tracker
  • Build a weight tracker
  • Build a hydrate tracker

If you are looking to join drchrono, build an app on top of onpatient’s FHIR API and impress us! The way to do this is to

  1. Create a drchrono account at
  2. Add test patient in drchrono at drchrono here after you signed up and logged in.
  3. Invite the patient to within drchrono here, use your email address so you get the patient email.
  4. Create an account with the email invite from drchrono, set a password.
  5. Sign in and go to the API page app page and start building.

Also post your code publically on Github as a resume builder and that the drchrono engineers can take a look at what you have built.

As you build please let daniel[@]drchrono[.com] and jian[@] know how things are working and if something is broken. This is a VERY new API so we are looking for real-time feedback.

This is a great project that someone built recently on the drchrono medical practice physician API and the onpatient patient API.

( This is a draft of a hackathon project to build on top of the onpatient FHIR API. I will be adding more over the next several days. )

How to Present to Investors on Demo Day

Michael my cofounder at YC demo day.

Pitching at demo day can be stressful. Below are three of the best articles I have seen around on pitching, I recommend reading them all if you are going into a demo day!

A quick pitch to Anne Wojcicki

Always have your pitch ready.

This is the drchrono slide deck we used at demo day, it will give you some insight into how simple and focused a pitch has to be
