Michael O'Neill is a co-founder and partner at Overture VC who focuses on early-stage climate tech investing with $1M-$3M checks, where every portfolio company receives government-affairs support from Boundary Stone Partners as part of the firm's embedded policy approach. As a founding partner of a deliberately compact team, he maintains direct accessibility for climate founders rather than operating through institutional channels, positioning himself as a climate operator-plus-policy investor rather than a generalist VC.

Notable Investments
Overture VC is founded and led by former Obama White House and U.S. Department of Energy officials who focus on sectors where public policy is central—energy, AI, resilience, and industrial transformation—rather than broad climate categories. Every portfolio company receives government affairs support from Boundary Stone Partners, a climate-focused lobbying firm founded by one of Overture's co-founders, effectively bundling venture capital with embedded public-sector strategy for founders who must unlock government incentives at scale.
