Frequently asked questions
Who runs investment decisions at HLM Venture Partners?
The firm is led by a long-tenured partnership group that includes Marty Felsenthal, Peter Grua, and Edward Cahill. They have managed the firm together since the 1990s, making investment decisions collectively. Each partner brings specific domain expertise across healthcare services, digital health, and medical technology.
What investment stages does HLM Venture Partners target?
HLM invests primarily at early-stage, growth, and expansion stages, often serving as the first institutional investor in a company's capitalization. The firm will also participate in later-stage rounds for existing portfolio companies. Its investment range typically spans seed through growth equity in the healthcare sector.
Which sectors does HLM explicitly avoid?
HLM is a healthcare-only investor and does not invest in sectors outside of healthcare services, digital health, and tech-enabled care delivery. Within healthcare, the firm does not typically invest in drug discovery, medical devices requiring FDA pre-market approval, or traditional biotechnology.
How does HLM Venture Partners source proprietary deal flow?
HLM sources deals through a network built over four decades of healthcare-only investing. The firm's partners have deep relationships with health system executives, payor leaders, and repeat healthcare founders. HLM also receives referrals through its portfolio company CEOs and the broader Boston-area healthcare innovation ecosystem.
Does HLM participate in fund commitments or only direct deals?
HLM is a direct investor and does not operate a fund-of-funds strategy. The firm invests its own funds directly into healthcare companies. HLM may co-invest alongside other venture firms and strategic healthcare investors in larger rounds.
