Accelerators aim to “accelerate” the life cycle of young innovative companies. Start-up accelerators support early-stage companies by providing access to mentors, investors, corporate partners, and customers through organized events and workshops. Start-ups typically enter accelerators on a competitive basis for a fixed period of time as a cohort of companies. Companies will work through specific pain points and milestones, such as the customer discovery process and pitch development. 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.
