Josh Kopelman is a former multi-time founder who took his first company public in his 20s and sold two others to eBay and Symantec, bringing deep "zero to IPO and acquisition" operating experience to early-stage investing. He's known for creating the "Venture Arrogance Score," a quantitative framework that tests whether very large funds' return expectations are realistic by calculating how much exit value a mega-fund would need to capture to deliver strong returns.
