Not long after selling software company Endeca to Oracle in 2011 for over $1 billion, Steve Papa called Bessemer Venture Partners with a hot tip. He said three of his best engineers were working on something new that Bessemer, which had previously backed Endeca, would be crazy not to fund. Kent Bennett, who'd been a junior associate on the Endeca deal, fielded the call. He told Papa there was some empty space at the firm's office in Boston that his people could use.
