MassChallenge
How to get into MassChallenge according to the founders that did it
Our take
Best if you want MassChallenge's mentor and corporate-partner network without giving up equity or a fee, and can put in the hours to use it. A weak trade if you need money up front — the cash comes only as competitive prizes most teams leave without.

We asked the founders how MassChallenge really went.
Every interview behind this page is one we ran ourselves. The numbers and quotes come straight from founders who went through MassChallenge, in their own words.
Who MassChallenge is for, and who should skip it.
Best for
- You are early stage and want a serious mentor and corporate-partner network without giving up any equity
- You can put in real hours, since the program rewards the founders who show up and chase the mentors
- You want the credibility and validation that a top-ranked, equity-free accelerator puts on your company
- You are open to coaching and customer-discovery work, not just hunting for a check
Skip it if
- You need guaranteed funding up front, since money here arrives only as competitive prizes at the end
- You cannot commit the hours, because the program washes past founders who treat it as passive
- You want a small, tight cohort, since classes run well past a hundred companies
- You already have a team and traction and only want capital
What it's actually like at MassChallenge
MassChallenge does not run like a bootcamp where everyone marches through one schedule. It runs more like an open campus. You join a cohort of more than a hundred companies, start with an in-person kickoff in Texas or Boston, then work through mostly virtual programming you shape around your own startup. The mentor network is the core of it, and how hard you tap it is up to you.
Ellen Williams, who went through the program as EVP of business development at Exum Instruments, described the format founders keep coming back to.
MassChallenge runs almost like a choose-your-own-adventure. You get access to a large database of mentors.
That flexibility cuts both ways. The cohort is large, the calendar is packed, and nobody chases you. The founders who got the most out of it treated MassChallenge like a place they lived rather than a course they logged into. Nicholas Seet, CEO of Undesert, drew the line plainly.
How much you get out of MassChallenge depends entirely on how much you put in. It's the difference between living on a college campus and taking an online course.
The same openness lets you skip what you do not need. Alejandro Fernandez, cofounder and CEO of The Whisper Company, found that the optional structure was the point.
You're not required to attend every session, so you can tailor the experience to your startup's needs.
The trade-off is overload. With more mentors, sessions, and introductions than anyone can attend, the founders who thrived picked their spots and let the rest go.
What you give, and what you actually get
The deal at MassChallenge is unusual, and it is the first thing most founders mention. There is no equity and no fee. You do not hand over a slice of your company, and you do not pay to take part.
Michael Kadish, CEO and cofounder of Incentivize, named it as the core of the appeal.
MassChallenge doesn't take equity and doesn't charge a participation fee, which is a big part of the appeal.
What you do not get is money up front. Funding at MassChallenge comes as a competition rather than an admission perk. At the end of the program, companies pitch a panel of investor judges for a pool of non-dilutive cash prizes, and only a handful win. Awards have ranged from around $25,000 to $100,000 in some cohorts, with top prizes reported as high as $350,000 in others, and most founders leave without one.
Brett Johnson, cofounder and CEO of SwitchedOn, thought that structure was underrated.
You get the resources, the courses, and the mentorship throughout, and then a real shot at non-dilutive capital at the end. Money on the table without giving anything up.
The rest of the value comes in kind. Founders pointed to steep discounts on tools like HubSpot, covered hosting on Amazon Web Services, and introductions to corporate partners such as Shell and KPMG. None of it touches a cap table, which is the whole point.
How founders actually got in
MassChallenge is genuinely selective. In a competitive year, roughly a thousand companies apply and only about ten to twelve percent make a cohort. The funnel starts with a written application covering the problem, the market, the team, the financials, and a pitch deck. Clear that, and you move into pitch rounds, often a recorded video and a live session in front of a panel of industry judges who score you and leave written comments.
Those comments are the part founders valued most, and you get them whether or not you advance. Tony Ma, CEO and cofounder of Benten Technologies, needed every round of that feedback.
It took us three tries to get in. The useful part of their process is that reviewers give feedback, so you actually know what to fix.
What the judges weigh is less about polish than fit. They look for a real problem, a large addressable market, and a team that can adapt and take coaching. Founders who showed up trying to teach the room their way did worse than the ones who came willing to listen.
What the founders said actually helps you get in, in their own words.
- Align tightly with MassChallenge's criteria, including its focus on impact and ESG goals
- Lead with a big problem and a large total addressable market, explained clearly
- Package and present the idea well, since it separates you from less organized early-stage teams
- Lean on a diverse or experienced team, and show you can listen and be coached
- Back the story with traction, awards, or active customer engagement wherever you have it
One more thing helps. Several founders came in through a connected incubator or applied to a specific industry track like FinTech or HealthTech, where the programming and the judges are matched to what you are building.

Questions founders ask about MassChallenge.
Around 10%. In a competitive year roughly a thousand companies apply and only about 130 to 150 make a cohort, after a written application and one or more rounds of pitching to panels of industry judges.
Yes. MassChallenge takes no equity and charges no participation fee, which is one of the main reasons founders choose it. The trade is your time, not a slice of your company or a check you write.
You join a large cohort, start with an in-person kickoff in Texas or Boston, then work through mostly virtual programming and a deep mentor network you tap on your own schedule. At the end, companies compete in a pitch for non-dilutive cash prizes, and only a handful win.
About four months, though it varies by track and cohort, with shorter one-month options and more intensive three-month versions. It does not require full-time hours, but founders said you get back what you put in.
It depends on what you need. If you want a strong mentor and corporate-partner network without giving up equity, and you can put in the hours, founders rated it highly. If you need guaranteed funding up front, the cash comes only as competitive prizes at the end, and most teams do not win one.
