Investment thesis
Boston Harbor Angels targets capital-efficient early-stage companies near commercialization with defensible competitive advantages that can reach profitability on less than $5M in equity and deliver at least a 10x return within five years. Members provide strategic guidance beyond capital and participate in syndicated deals with other angel groups and early-stage venture funds. The group seeks entrepreneurs who are coachable yet capable of building successful businesses independently.
