Mike Walsh is the Founder and General Partner of Structure Capital, a San Francisco-based seed-stage venture firm he launched in June 2013 using proceeds from his early investment in Uber. Before founding the firm, he designed missile defense systems, sold pollution control equipment, and founded Leverage Software, an enterprise social networking company he sold in 2011. Walsh’s investment thesis targets seed-stage companies in sectors like marketplaces, sharing economy, social commerce, education, and parenting, with a focus on underutilized assets and resource efficiency. He typically invests between $150,000 and $1.5 million per deal and often acts as a lead investor in early rounds. Notable portfolio companies include Uber, Salesforce, Carta, HiFi Labs, and Surf Air, with Walsh serving as a first-round investor in Uber and an early angel in Salesforce. His distinctive point of view centers on a 10-criteria evaluation framework that prioritizes founder grit, market size, and whether 1,000 socially connected people would genuinely use the product, with up to 75% of his decision relying on a gut check.
