10 Accelerators Helping Startups Grow to the Next Level Admission to an accelerator program offers help every startup founder can use.

The increasing number of startups is related to more than the economy growing again. It's a chicken-and-egg scenario. It's unclear which came first, the rise in startup accelerators or the number of startup founders looking for help.
