There are nearly 50 Greater Boston startup accelerators, incubators, and similar support programs. These programs provide selected early-stage ventures with office space, capital, mentorship, peers, industry connections, investor introductions, and other support. These spaces aren’t just for founders — they are great connection points for those who want to be involved with innovation in their industry through their events and partnership opportunities.

Boston Startup Accelerators

Many of these programs are focused on specific sectors or groups of entrepreneurs. Some are private / public / academic partnerships being run for the business development or shared economic benefits, while others are investment programs that ultimately seek a return from the equity they receive in exchange.

We’ve sorted all these programs into five sections; you can look through them all or skip ahead to the ones most relevant to you:

Startup Accelerators in Boston

Accelerators are programs that aim to take already-promising startups and accelerate their growth. They usually admit groups of startups as a cohort a couple of times per year. They have a set time period for the program, usually invest capital, and often culminate in a demo day to press and investors. Many accelerators take a small percentage of equity in return for their investment.

MassChallenge – Originally started with backing from the City of Boston and Massachusetts state government, MassChallenge operates independently to foster job-creating startups across all industries.

MassChallenge runs a 4-month accelerator program that provides mentorship, office space, education, industry networking, and community.

Startup Incubators in Boston

Incubators are less-structured programs that support startups with space, mentorship opportunities, access to industry experts and connections, and a community of peers, but are less likely to offer capital (or require equity). Incubators are more likely to admit startups on a rolling basis, and are often less timeline-driven than accelerators.
