Thirty-5 Capital
Thirty-5 Capital is a Chicago-based private equity and growth equity firm investing in early-stage and expansion-stage technology companies nationally.
Thirty-5 Capital
Founded in Chicago, Thirty-5 Capital established itself as a sector-focused private equity firm investing at the intersection of early-stage venture and growth equity. The firm's geographic roots in the Midwest inform a sourcing strategy tilted toward overlooked innovation hubs between the coasts. The firm's investment strategy spans early-stage startups through established growth companies, concentrating on enterprise software, AI/ML applications, digital health platforms, fintech infrastructure, and industrial technology. Rather than passive venture minority positions, Thirty-5 Capital pursues a hands-on deployment model blending venture-stage entry with the operational engagement characteristic of traditional private equity. The firm invests nationally from its Chicago base, with a watch list that includes emerging ecosystems in the Midwest, Southeast, and Texas. Thirty-5 Capital operates as a nimble, principal-driven firm where investment professionals work directly with portfolio company management teams on go-to-market execution, product strategy, and operational scaling. The firm's structure emphasizes concentrated portfolio construction, enabling deep engagement with each holding. Thirty-5 Capital's structural profile reflects the blurring of venture capital and private equity boundaries increasingly common among Chicago growth investors, combining early-stage risk appetite with a repeatable value-creation playbook more typical of control-oriented buyout firms.
