Why we picked it When a program can't or won't name its raise rate, this is the number to hold them to: across 8,580 companies in 408 accelerators in 176 countries, accelerated startups were only 3.4% more likely to raise VC and pulled in about $1.8M more in the first year. That is real but modest, so it arms you to read a program's fundraising claims with a cold eye and to notice that outcomes depend heavily on program design, not the accelerator label.
Do Accelerators Improve Startup Success Rates?
From Knowledge at Wharton by Valentina Assenova and Raffi Amit (Wharton) 8 min read
- The average accelerator bump is real but small (3.4% higher odds of raising, roughly $1.8M more year one), so treat any program promising transformation as making a claim it has to back with cohort data.
- Outcomes hinge on specific design elements like pitch training and industry-specific guidance, not the brand, so ask what the program actually does week to week.
- The right accelerator depends on your stage, sector, and founder experience, which means a top-ranked program can still be wrong for you.
