Spring Lane Capital

Spring Lane leverages its team's decades of hands-on development and operating experience to build relationships directly with project developers. Its stated model of maintaining 'fewer, deeper relationships' suggests a reliance on developer networks, industry partnerships, and its own portfolio operations group to identify companies before they reach broad auction processes. The firm's specific vertical focus narrows the funnel to a small subset of infrastructure developers.

It provides both, which is unusual. Spring Lane describes its approach as 'tailored project finance and corporate equity,' meaning it can invest at the parent-company level as venture or growth equity and also provide project-level debt or structured capital to finance specific installations. This dual capability is designed to match the capital needs of developers facing the 'missing middle' financing gap between venture-scale and infrastructure-scale funding.

The firm targets growth-stage platform companies that have moved beyond proving their technology and need to finance the build-out of multiple commercial-scale projects. It explicitly identifies its niche as the 'missing middle,' where a developer has validated unit economics at small scale but cannot yet access conventional project-finance markets. This sits between early-stage venture and mature infrastructure investing.

Investment decisions are led by the three co-founders and partners: Christian Zabbal (Managing Partner), Nikhil Garg (Partner), and Rob Day (Partner). The firm has not publicly disclosed a dedicated investment committee beyond this partnership group. Its flat team structure of 15 professionals, with titles ranging from Partner to Associate, suggests the three partners hold primary decision authority.

Spring Lane does not publish an explicit negative screen, but the firm's mandate is tightly scoped to decentralized, low-carbon physical assets. It does not invest in biotech, enterprise software, consumer goods, or large-scale centralized infrastructure like utility-scale wind farms or long-haul transmission. Its absence from the mobility software or carbon-credit trading markets also suggests a deliberate avoidance of intangible or financialized climate assets.

There is no public disclosure of a philanthropic foundation or donor-advised fund affiliated with Spring Lane Capital or its principals. The firm's website frames its mission entirely through its investment mandate, describing impact in terms of carbon-reduction equivalents for its portfolio, rather than through a separate charitable vehicle.

Spring Lane does not publicly outline a formal co-investment policy, but its structure — combining equity and project finance in small-scale infrastructure — is well-suited for co-investing. By providing flexible capital in a segment avoided by large funds, it likely attracts co-investing partners seeking exposure to distributed energy and circular-economy assets without building their own in-house operating teams.
