Investment thesis

The Builders Fund targets the 'Missing Middle' in impact capital markets—a gap between venture and buyout stages where companies are underserved by traditional private equity and overcharged by banks. The fund leverages a team of experienced operators and entrepreneurs, including over thirty founding LPs who serve as operating partners, to guide portfolio companies in decarbonizing the economy, fixing food systems, improving access and affordability, and building more equitable, sustainable futures through authentic, activist brands.
