Equity-free vs. equity accelerators

Some accelerators take equity in exchange for investment; many government, university, and nonprofit programs are equity-free and provide grants or stipends. Bootstrap Directory highlights non-dilutive and founder-friendly options.

What accelerators provide

Beyond capital, accelerators offer structured curriculum, mentor networks, customer and investor introductions, and demo days. The right program can compress months of progress into a single cohort.

Find programs near you

Many accelerators prioritize local founders or require in-person participation. Browse by state and city to find programs you can realistically join, plus industry-specific cohorts for your sector.

How we keep listings useful

Programs are published with application URLs, deadlines, eligibility, and terms where available, and closed or inactive cohorts are removed from public results.
