Bullpen Capital invests in post-seed companies that have achieved product-market fit, but have not yet proven sufficient market scalability to raise a major VC round. We invest in companies that have an operational plan to hit big milestones within a 12-month period, and we work closely with the companies in our portfolio to develop this early traction into large, sustainable businesses.
Seed financing is now more of a process than an event, with multiple rounds of investment layered into the early stages of startup companies. The "post-seed" stage is often the inflection point of value, the last lean money in before a “super-sized” A round. Bullpen’s strategy aims to provide leverage for founding teams, who can minimize dilution to maintain ownership and control of their companies, while retaining the option of choosing either a quick acquisition or raising major growth capital to go for a big win.
