YC has just closed a new $8.25 million fund

We're happy to announce we've just closed a new fund of $8.25 million. The investors are a superset of those who invested in our previous fund: Sequoia Capital led again, and in addition we have a number of prominent angels, including Ron Conway, Paul Buchheit, Aydin Senkut, XG Ventures, and Geoff Ralston. It has been pleasant to work with investors who understand startups so well, and we look forward to continuing the relationship.

The new fund is more than four times larger than the preceding one, partly because it's meant to last for several years, and partly because we're going to use it to increase the number of startups we fund. It looks like we will have at least 35 in the summer 2010 funding cycle. (The number could increase, because we now consider late applications till just before the start of each cycle.)

The previous YC funding cycle, winter 2010, had 27 startups. Already 20 of them (74%) are either profitable or have commitments for further funding.

With the summer group, Y Combinator has now funded 207 startups, including Airbnb, Bump, Cloudkick, Clustrix, DailyBooth, Disqus, Dropbox, Heroku, Heyzap, Justin.tv, Loopt, Posterous, RethinkDB, Reddit, Scribd, Songkick, Weebly, Wepay, Wufoo, and Xobni.
