Accelerators aim to accelerate the life cycle of young innovative companies. Startup accelerators support early-stage companies by providing access to mentors, investors, corporate partners, and customers through organized events and workshops. Startups typically enter accelerators on a competitive basis for a fixed period of time as a cohort of companies. Typically, companies will work through specific pain points and milestones to accelerate the life cycle of their companies. The programs typically run for 3-6 months and culminate in a public pitch event or demo day where start-ups have the opportunity to win cash or in-kind prizes. Accelerator staff help mitigate market barriers by connecting start-ups with mentors, investors, corporate partners and customers through organized events and educational workshops.
