Adam Rentschler

Adam RentschlerCEO, Co-Founder

Adam is a serial entrepreneur who has spent his 26-year career running, fund-raising for, investing in, coaching and mentoring startup companies. He has raised money from a wide variety of sources including strategic venture capital, venture debt, friends and family, and a U.S. government intelligence agency. As a very junior VC, Adam had one positive exit. He co-founded, ran and sold betterVote.com in 2000 as the dot-com bubble burst. Valid Eval was born of Adam's frustration with poor learning outcomes for companies competing for grants, prizes and acceptance into accelerator programs.
