Accelerators are now an integral part of the startup ecosystem. For some, especially first-time founders, it is sort of becoming a checkbox item: go through an accelerator. Serial entrepreneurs, as a rule, would say they don't need to, because they already know what to do.
Some people say that accelerators are only good for the companies that haven't yet raised financing. They argue that if the company has raised capital, then it's too far along for an accelerator and wouldn't benefit from it.
