The business accelerator was first launched in Seattle, USA in October 1999 and has now spread to France, the UK, Canada, Australia, Mexico and other countries.

Business accelerators appeared relatively late, but have developed very rapidly with the strong encouragement of the US government, with US accelerators being the most successful.

Since then, accelerators have received great attention from the United States and other countries around the world and have developed rapidly.

There are three levels of U.S. accelerators.
