Founders Fund already stands out for backing startups with radical ideas, including Counsyl, Hampton Creek, Planet Labs, and SpaceX. Now the venture firm is making a formal commitment to funding startups in aeronautics, life sciences, nanotechnology, and other geeky realms. Founders Fund has dedicated a small percentage of its new $1 billion fund to a new initiative called FF Science, through which the firm will make seed-stage deals.
