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.
