Jack Walsh

Jack Walsh is a Vice President at Pine Street Capital Partners, a Wellesley, Massachusetts–based investment firm founded in 2004 that provides non-control debt and equity capital to established lower-middle-market companies. He joined the firm in 2017 as a Senior Associate and has since been promoted to Vice President. His responsibilities span investment evaluation and execution, portfolio management, and deal-flow generation, and he currently serves as a board observer at portfolio company Full Spectrum Software.

Before Pine Street, Walsh was an Associate at Citizens Bank in Boston, where he worked on the leveraged finance team, evaluating and underwriting leveraged finance opportunities for middle-market and mid-corporate companies across a range of industries and transaction types. He also spent time in Citizens' restructuring and workout group, giving him exposure to distressed and complex credit situations in addition to standard underwriting.

Walsh earned a Bachelor of Science from Skidmore College, where he captained the varsity hockey team. His background is squarely in credit and finance rather than early-stage/angel investing, consistent with Pine Street's focus on cash-flowing, established businesses.
