More than a course. More than a community. More like a CrossFit gym - kicking your butt and holding your hand while you build and grow.
Day One is an 8-week, cohort based program designed for idea-stage founders.
Starting a business is hard. Don't do it alone.
Join talented founders from across the globe who are building alongside you. Surround yourself with experienced, successful mentors. Find your tribe and set yourself up for a long run of success.
Take away the guesswork. Follow a proven playbook
Follow a company-building playbook created at world-class venture studios. Receive tactical guidance while you put the playbook into action. We've removed the fluff so you can hone fundamental company-building skills.
Time is Money.
Avoid Rookie Mistakes.
Save yourself time, money and heartache with answers and advice from experts. Attend weekly mentor sessions, office hours, pitch reviews and peer collaborations to level up while you get down to work.
Who is Day One for?
There are three good ways to answer that question.
Day One is designed for idea-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 accelerate forward.
Day One is for doers only. Couch Potatoes need not apply. The best Fellows are those who are collaborative and want to build momentum by being a part of a community.
Day One is for founders building both venture backed and non-venture businesses. In fact we have a soft spot in our heart for founders exploring and building bootstrapped, profitable businesses.
"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
