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.
Y Combinator adjusts standard deal terms for its Winter 2021 batch and beyond
The first would see the size of the standard deal for YC startups decline from $150,000 for 7% (roughly a $2.1 million post-money valuation) to $125,000 for the same equity (or roughly a $1.79 million post-money valuation).
Y Combinator is also imposing a ceiling on its pro rata investing rights. YC will only take pro rata up to 4% of a subsequent round's size, which is smaller than the 7% equity stake the accelerator typically takes. If Y Combinator holds less than a 4% stake in a company, it may exercise its pro rata right for the lesser percentage stake.
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).
Y Combinator moves to Silicon Valley year round
Previously, Y combinator had alternated between Cambridge, MA and Silicon Valley.
