While both accelerators and incubators aim to support startups, they differ in several key ways. Accelerators are generally more structured, operate on a fixed-term basis, and focus on rapid growth. Incubators, on the other hand, provide a more flexible, long-term nurturing environment, often without a predefined end date. Additionally, incubators may focus more on office space and basic resources, whereas accelerators emphasize intensive training and mentorship.
