Paul Martino is the Co-Founder and Managing General Partner of Bullpen Capital, a venture firm he established in 2010 after serving as an active angel investor in early rounds of Zynga, TubeMogul, and Udemy. His investment thesis focuses exclusively on the “post-seed” stage, targeting companies between seed and Series A that have demonstrated early product-market fit but need capital and coaching to reach a larger round. Bullpen Capital invests across all sectors and geographies, with no style drift over 15 years, seeking overlooked entrepreneurs who need time to scale before a big Series A. While specific check sizes and lead/follow behavior are not publicly detailed, the firm’s model emphasizes providing capital alongside coaching and extended runway. Notable portfolio companies include FanDuel, Udemy, Ipsy, SpotHero, Namely, and Classy, with Martino personally leading several of these key investments. Martino distinguishes himself as an eight-time founder, patent holder with over a dozen core patents in social networking and big data, and a public voice on the “Series A crunch” and data-driven founder discovery.
