Y Combinator is a San Francisco-based startup accelerator and early-stage investor founded in 2005. YC accepts applications from startups anywhere in the world and runs in-person batches in San Francisco. Its standard deal invests $500,000 in each accepted company: $125,000 for 7% equity and $375,000 through an uncapped MFN SAFE. YC is sector-agnostic and has funded companies across B2B software, fintech, consumer products, industrials, healthcare, education, and real estate and construction. It typically works with companies at the earliest stages, including teams that may not yet have revenue, a product, or a fully developed idea.
