Do Accelerators Improve Startup Success Rates?

Valentina Assenova and Raffi Amit (Wharton) · Knowledge at Wharton Free Intermediate

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.

  • 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.
