Y Combinator pioneered a new model for funding startups. Their major innovations include funding companies in batches, giving standardized terms, and having weekly dinners that culminate in a demo day to a group of investors. The firm was originally funding startups in Cambridge, MA for their summer batch before moving both summer and winter batches to Mountain View, CA.
Y Combinator’s motto is "Make Something People Want". The program aims to focus the founders on further developing their product, team, and market, as well as refining their business model, achieving product/market fit, and scaling the startup into a high growth business.
The program culminates at Demo Day. An event where startups present their business to a selected audience of investors. As of 2016, Y Combinator had invested in ~940 companies including Dropbox, Airbnb, Coinbase, Stripe, Reddit, Zenefits, BuildZoom, Instacart, Twitch.tv, Machine Zone, Weebly, Paribus, and Chinese startup Raven Tech. Non-profit organizations can also participate in the main YC program.
Y Combinator also operates Hacker News, a social link sharing site where users can submit and share news. The front page consists of 30 links at a time, sorted via an algorithm that takes into account upvotes from the community. According to SimilarWeb, the site receives over 20 million visits per month.
New Standard Deal - post-money SAFE
Y Combinator announced the change to the standard investment deal. YC increased their investment from $120K to $150K. The $150K investment for 7% will be made on a post-money cap SAFE (Simple Agreement for Future Equity).
