Who is Day One for?

Day One is for early-stage founders who haven’t hit product-market fit yet. You can be right at the starting line, or somewhere in the messy middle. Day One will help you get down to business and accelerate forward.

Day One is for collaborators who want to build momentum. by being a part of a community. That doesn't mean you have to be an extravert, but you do need to have a community-first orientation.

Day One is for founders building all kinds of business. Whether you're VC backed or bootstrapped or something in between, Day One is here for all the different entrepreneurial journeys - especially if you're not sure.

Day One Fellows come from the world's top companies:

"Day One is high touch, unlike any other program out there. We would share what we're working on, share the challenges that we're facing, and get feedback and ideas from the group and mentors and solve the problems together. That's been incredible as we build this new venture. I would definitely recommend Day One to any person who's thinking about becoming an entrepreneur."

- Berta Argente, Business Designer at Polymath Ventures, Cohort 1 Alumni

"I'm amazed at the depth and breadth of experience across the cohort. Day One did an amazing job at gathering a diverse, inspiring group of entrepreneurs and mentors."

- James Clements, Founder, Old Friends, Cohort 1 Alumni

"I came to Day One with the goal to really learn how to do customer discovery the right way, and to be able to know if I was working on something that people wanted - because I think you can spin your wheels trying to solve a problem that nobody really cares about. And with Day One, I was able to learn from both my peers and experts and come away knowing "this is what we're going to do."

- Julia Hutchins, Founder, Bell Bird, Formerly co-founder, Apostrophe Health, Cohort 1 Alumni

"I love having such a great community to lean on. Although it's giving me the classic existential crisis - did I really need to go to MIT? Day One is more than enough!"

- MIT Sloan MBA Student, Cohort 1 Alumni

Mentors & Speakers

Learn from serial founders who have achieved $1B exits and investors who manage $50M+ venture funds. These are just a few of the founders, operators and investors who guide, support, advise or teach within Day One.

Got questions? We've got answers.

Am I a fit for Day One?


Our name is Day One for a reason, so you can't be too early in your entrepreneurial journey. You might be too late if you have achieved product-market fit and are more focused on scaling than you are on getting close to your customer, developing your first product(s), and raising your first rounds of capital. Because we provide 1:1 guidance that takes into account your context, and have developed playbooks for the common fundamentals of building a startup, almost every founder who is looking to accelerate, expand their network, find support, and learn is a fit.


Day One is also a fit for entrepreneurs who are building all kinds of businesses - whether that's a venture-backed startup, a bootstrapped business, a side hustle, an agency, or anything in between. The early days are a special kind of hard and we're focused on helping founders navigate these treacherous waters when they need the most support.



What do you look for in applications?


We try to infer through your application the slope of your (personal) growth curve.  We are far more concerned with your drive to learn and motivation than we are with your years of professional experience.  Do you take (and seek out) feedback?  Do you understand that feedback is what makes you better (even if it is sometimes hard to hear)?  Do you realize that entrepreneurship is a marathon and not a sprint?  Do you value community and strive to contribute as much as you receive?  We are looking for people who answer yes to these questions.  As you can imagine, it isn't always easy to infer this from a written application.  Don't overthink the application - just keep these things in mind.



What's the application process?


Every application is reviewed by our team. If we think there's potential to be a great Day One Fellow, we'll invite you to a 30 minute interview where we'll look to get to know you beyond the application, and give you a chance to get to know us and ask questions. We make almost all decisions after this first interview, within a couple weeks of applying. 



What level of time commitment is required?


We suggest reserving 5-10 hours a week to make the most of the program. You'll want to make time for sessions like workshops, office hours, mentor sessions, networking events and talks,  as well as time to work on your business and connect 1:1 with your peers. 


The program is designed to be flexible and no session is must-attend. Many Fellows work full time and do this program on the side, while others are busy building full time. If a busy week comes up and you have to prioritize elsewhere, you'll be able to catch recordings of sessions, collaborate asynchronously, and get back to live sessions the following week. And in the end, if you find that the workload is too heavy, you can always defer to a later program or get a refund.  

Speak to us if you have concerns



Is Day One completely virtual? 


Yes! Even before the pandemic made virtual communities a must, Day One was designed to be virtual so that we could extend support and opportunity wherever we could find entrepreneurs... meaning, everywhere. When local activities come back, we're excited to build local chapters, but for now, Day One is fully virtual.



If I want to do this program with my cofounder, can I get a discount?


Yes!  Here is how it works.  The first founder pays full price.  Any other founder after that (up to three) pays 50%.



Do you offer any other discounts or scholarships?


We offer early applicant pricing which allows you to join for a significant discount. We also have a limited number of partial scholarships to offer. You can indicate on your application that you'd like to receive financial aid.



What happens after the 10 week program?


After the  10 week program, you'll continue to be a part of the growing and vibrant Day One Fellowship Alumni community. Inside this community, you'll be able to connect with Fellows from every cohort, and access all the content we produce, playbooks we create and the sweet, sweet perks we aggregate for you. You'll also get access to talks and events just for Fellowship alumni.

What's the story behind Day One? 


Day One was first conceived by Andrew Hutton while he was launching new startups at Human Ventures, a startup studio. During the spring of 2020, as a pandemic was setting in, the thesis behind Day One came together: create a virtual community for early stage founders that was focused equally on bringing people together AND guiding/pushing/accelerating them through their entrepreneurial journey. The question Andrew was trying to answer was "how can we scale a venture studio, what would that look like?" The answer is Day One. Shortly thereafter, Rahul Brahmbhatt joined as co-founder and COO, and the rest is history. Together, Andrew and Rahul have advised hundreds of founders and supported and invested in dozens of businesses. With Day One, the mission is to support thousands more.
