Plymouth Growth focuses on the "magnificent middle" of B2B technology companies with $3-15M in revenue that are too small for most growth equity funds but beyond early-stage VC, particularly targeting founder-led businesses in the Midwest and other regions underserved by coastal investors. The firm combines venture-style follow-on capital with a buy-and-build strategy that supercharges growth through transformational acquisitions, positioning itself as a long-term partner for "gritty" B2B tech companies that others dismiss as "too small" or "too boring."
