An accelerator is a fixed-term, cohort-based program that takes a startup that already has a product and pushes it toward its next round, usually for a small equity stake. An incubator is a longer, looser program that helps a team shape an idea or early prototype, often with no fixed end date.

Stage: accelerators usually want a team with a working product and early users, while incubators accept ideas, prototypes and solo founders.
Duration: an accelerator runs a fixed term, commonly a few months, and ends with a demo day. An incubator has no fixed length and a team can stay for as long as the program allows.
Intake: accelerators admit a cohort at once through a competitive application. Incubators often admit on a rolling basis and can be less selective.
Money: accelerators commonly offer a small investment for equity, while incubators often charge a fee, take no equity, or offer space and services instead of cash. Terms vary widely, so read them before you sign.
Goal: an accelerator is built to get you to a fundraise or a growth milestone fast. An incubator is built to help you work out what to build.
Who runs them: universities, corporates, governments and investors all run both. Who runs a program tells you more about its incentives than its label does.
If you have a product, some users and a clear story about what you will do with the next few months, apply to accelerators. If you are still testing whether the problem is real, an incubator, a university program or a build-in-public stretch is often the better first move.
Do not apply to an accelerator just to find out if your idea is good. Reviewers read the application as evidence that you are ready to use a short, intense program well.
Founders treat the two words as interchangeable and apply to everything. Read the terms: equity taken, fees charged, expected commitment, and what happens after the program ends.
Another common mistake is sending a vague idea deck to an accelerator that expects traction. Your application deck should match the stage the program says it takes.
