"In the Studio" opens its doors this week to an entrepreneur who co-founded, built, and sold his two startups to large technology companies, then teamed up with his co-founding partner to invest their own capital in startups, which provided the basis for their current institutional angel fund and an impressive, diverse array of seed stage investments in consumer technology and infrastructure. Before Josh Felser co-founded Freestyle, an institutional angel fund, with his partner David Samuel, they both built successful internet businesses, Spinner and then Grouper, which were both sold to larger companies.
