David Hehman is a lifetime entrepreneur who co-founded and sold five technology businesses before becoming a pre-seed investor at Underdog Labs, giving him unusually deep hands-on operator experience across multiple exits. He runs Underdog Labs as a boutique startup studio that works with very early-stage founders, personally leaning in to help de-risk the messy early phase and iterate to product-market fit rather than acting as a passive capital provider.
