Long River provided incredible value to our team, originally as lead Series A investor and all the way through our private equity round. Any entrepreneur who wants an early stage financial partner, not just an investor, should talk to the Long River team.
— John Roland, founder and CEO, Extreme Reach

Long River Ventures invests in seed and early stage companies in healthcare and IT.

We are a team of experienced entrepreneurs and venture capitalists and a diverse group of advisors and limited partners.

We seek exceptional entrepreneurs, funding them to support key business milestones in a capital-efficient manner. Long River typically leads or co-leads Series A rounds of $3-5 million, contributing up to $1 million with significant reserves for follow-on investments.

We invest primarily in the Northeast, both in the major venture markets of Boston and New York and in nearby regional markets. Our offices are in Boston and Amherst, Massachusetts.
