About

Founders Fund is a San Francisco-based venture fund that invests in revolutionary technologies. We focus on investing in smart people solving difficult problems - to do so, we will invest at all stages across almost any sector. Unlike many venture firms in Silicon Valley, this means that Founders Fund does not limit itself to internet-based technology and software. Founders Fund has and will continue to invest in areas including biotechnology, energy, hardware, and aerospace. Founders Fund was founded by Peter Thiel, Ken Howery and Luke Nosek in 2005 and raised its first fund that year. In 2016 Founders Fund raised a $1.3 billion fund, its sixth fund to date.
