Graphene Ventures

Nabil Borhanu is the Managing Partner and leads investment decisions. The firm operates with a lean structure, suggesting a centralized decision-making process rather than an expansive partnership committee model. Borhanu's technical background informs the firm's thesis at the intersection of material-science analogies and software investing.

Graphene Ventures primarily invests at the seed and Series A stages, where it can establish meaningful ownership early and support companies through multiple subsequent financing rounds. The firm's flexible capital base allows it to participate in follow-on rounds without the allocation constraints a traditional blind-pool fund imposes.

The firm leans on deep technical networks in the Bay Area, relationships with research universities, and connections with corporate R&D labs. This bottom-up sourcing model reduces reliance on the generic top-of-funnel inbound most Sand Hill Road firms process, and it aligns with the firm's preference for companies where physical infrastructure and software converge.

The firm's sector coverage includes enterprise software, artificial intelligence and machine learning, fintech infrastructure, digital health, mobility and transportation, property technology, agriculture technology, and the energy transition. The common thread is a focus on software platforms that reshape legacy analog industries, rather than pure consumer internet or standalone SaaS.

Graphene Ventures operates as a direct investor into early-stage companies and does not publicly position itself as a fund-of-funds or a limited partner in other venture firms. Its model is built around concentrated, conviction-led direct equity investments rather than diversified fund commitments.

Graphene Ventures is categorized as an asset manager with a private equity and venture capital mandate, not a single-family office. While its precise capital source has not been publicly detailed, it operates as an external manager deploying capital on behalf of its stakeholders rather than serving a single family's balance sheet.

The firm has not publicly outlined a formal co-investment program for external partners. However, its concentrated, flexible-capital approach means it can collaborate with other venture firms on a deal-by-deal basis without the constraints of a predefined co-investment allocation budget.
