Frequently asked questions
Who runs investment decisions at Halpern, Denny & Co?
Co-founders John Halpern and John Denny serve as the firm's managing partners and make all investment decisions. Their partnership has been stable since 1991, with no public record of an expanded partnership or external investment committee. The structure suggests every deal requires dual sign-off from the founders.
How does Halpern, Denny & Co source proprietary deal flow?
The firm sources almost entirely through its Boston and Northeast network, relying on founder-to-founder referrals and relationships built over three decades of early-stage investing. Halpern and Denny sit on boards rather than simply buying board observation rights, which embeds them into company networks that generate follow-on deal flow.

Which sectors does Halpern, Denny & Co explicitly avoid?
