A Business Accelerator is a program designed to support early-stage startups by providing mentorship, resources, and funding to help them grow quickly and succeed in the market.
Synonyms: Startup Accelerator, Business Growth Program, Startup Growth Accelerator, Accelerator Program

Business accelerators play a crucial role in the startup ecosystem by offering startups access to expert guidance, networking opportunities, and sometimes initial capital. This support helps startups overcome early challenges and scale their business faster than they might on their own.
Startups typically apply to join an accelerator program, which lasts for a fixed period, often a few months. During this time, startups receive mentorship from experienced entrepreneurs and industry experts, participate in workshops, and gain exposure to potential investors. Many accelerators culminate in a demo day where startups pitch to investors.
Well-known business accelerators include Y Combinator, Techstars, and 500 Startups. These programs have helped launch successful companies by providing structured support and funding.
