What is a startup accelerator?

A startup accelerator is a fixed-length programme, usually three to six months, that takes in a group of early-stage startups at the same time. Each startup gets mentoring, workshops, introductions and often a small investment. The programme ends with a demo day where the founders pitch to investors.

Accelerators are competitive. Well-known programmes accept a small share of applicants, and they select for teams they think can grow quickly.

What accelerators offer

  • Seed investment, typically in exchange for a small equity stake
  • Weekly mentoring from founders, operators and investors
  • A cohort of other founders working through the same problems
  • Introductions to investors, customers and partners
  • A demo day in front of a room of investors
  • Perks like cloud credits and software discounts

Not every accelerator invests or takes equity. Some are funded by governments, universities or corporates and charge nothing. Read the terms before you apply.

Frequently asked questions

How much equity do accelerators take?

Equity-based accelerators commonly take around 5 to 10 percent in exchange for their investment and programme. Many government and university programmes take none.

What is the difference between an accelerator and an incubator?

Accelerators are short, cohort-based and aimed at fast growth, usually ending with a demo day. Incubators are more open-ended and help earlier-stage companies develop over a longer period, often with office space.

Can I apply to more than one accelerator?

Yes. Most founders apply to several. Keep your core answers consistent, and tailor each application to what that programme focuses on.

Do I need a product to get into an accelerator?

Not always. Some accept teams at the idea stage, but a working prototype or early customers makes an application much stronger.
