Y Combinator

Overview

Y Combinator (YC) is a leading American technology startup accelerator and venture capital firm, founded in 2005 by Paul Graham, Jessica Livingston, Robert Tappan Morris, and Trevor Blackwell. It has been instrumental in launching over 5,000 companies, including notable names like Airbnb, Coinbase, and DoorDash. YC runs a rigorous three-month accelerator program four times a year, designed to support startups at various stages, from initial ideas to established companies.

The program offers seed funding, mentorship from experienced partners, and access to a vast investor network, helping startups enhance their products and fundraising capabilities. Founders also benefit from a strong community and alumni network, which provides valuable resources and connections. Additionally, YC operates Hacker News, a platform for technology discussions that serves both alumni and the broader tech community. With a focus on helping founders create products that meet market needs, it has established itself as a powerhouse in the startup ecosystem.
