About
Matt Rightmire is a venture partner at Building Ventures who combines more than a decade building Internet companies in Silicon Valley (joining Yahoo! pre-revenue in 1995, then COO of Efficient Frontier) with a decade-plus as an early-stage investor, giving him deep operator and investor pattern recognition for software, advertising, and marketplace businesses in the built environment space. After his Silicon Valley career, he deliberately moved back to New Hampshire and built his investing practice around backing high-tech startups in regions like New Hampshire and the broader Northeast, arguing that capital, talent, and connectivity increasingly support building meaningful tech companies far from traditional hubs.
