Atomic just raised $260 million more to build and fund its own companies Jack Abraham has a lot of confidence in what he’s building. Then again, you can’t be immodest or unsure of yourself if you’re going to bet exclusively on your own startups as an investor, which is precisely the model that Abraham’s San Francisco-based venture studio, Atomic , has followed since it was launched nine years ago. It all started with $10 million of largely Abraham’s own money, capital he amassed by selling his first startup, a local shopping engine called Milo, to eBay in 2010 for $75 million. Abraham had dropped out of Wharton as an undergrad with $500,000 from a professor who believed that Abraham — whose father founded ComScore — would himself be a company-building machine.
