Khosla Ventures

Activity from announced rounds

Activity in this selectionOct 24, 2026 · Climate tech · Jan 1, 2026

Khosla Ventures funds technology companies at seed, early and growth stages, including businesses tackling difficult scientific and engineering problems in energy, industry, healthcare and software.

Its investments in fusion and lower-emission cement illustrate an appetite for technical risk in markets where commercialisation requires more than a software launch. The firm also invests in AI and developer businesses, applying the same interest in technology that can change how an industry works.

Its Venture Assistance programme includes candidate shortlists, compensation and hiring-close materials, recruiting events and operator office hours in growth, product marketing, data and sales. Those are practical resources for founders assembling the team and commercial capability around a technical product.
