Structure Capital

Structure Capital is a Silicon Valley-based venture firm focused on early-stage investments with a unique twist: they are the self-described "Architects of the Zero Waste Economy." Founded by Mike Walsh and Jillian Manus in 2013, Structure Capital invests in startups that optimize underutilized assets and reduce waste, helping create more efficient and sustainable business models. Their portfolio includes high-profile companies like Uber, Airbnb, and The Muse, as well as mission-driven ventures like Copia and Lettuce Grow, which embody their zero-waste ethos. The firm tends to invest early, at the seed stage, with check sizes ranging from $250,000 to $2 million. Structure Capital emphasizes working closely with founders to build purposeful brands through their unique Brand Camp, a creative accelerator developed with the help of top advertising agency Goodby, Silverstein & Partners. This hands-on strategy aims to shape powerful, scalable businesses that align with the values of sustainability and social impact. Led by a diverse team with deep expertise across multiple industries, Structure Capital champions founders who combine innovation with empathy. Jillian Manus, known for her advocacy for diversity in tech, brings a wealth of experience from her roles in media and finance, while Mike Walsh brings a technical background and early investment wins, such as Salesforce. Together, they provide not only capital but mentorship and strategic guidance to their portfolio companies, helping them scale and thrive.
