Heinz Ventures is an operator-led early-stage medical technology investment firm founded in 2015 by Eric S. Heinz. We invest in pre-seed and seed-stage MedTech companies developing regulated products, with a focus on the U.S. Heartland. Our approach combines capital with more than 25 years of operating experience across medical device engineering, product development, commercialization, corporate development, M&A, and governance. Heinz Ventures works closely with founders and management teams on the issues that matter most in early-stage MedTech: product and regulatory strategy, commercialization, strategic partnerships, governance, financing, and positioning for future transactions. In addition to venture investing, Heinz Ventures selectively provides independent board, business development advisory, and medical device expert witness services. Our objective is simple: bring operator-level judgment to high-stakes decisions in regulated medical technology.
