Activity from announced rounds

Activity in this selectionUnited States · Oct 9, 2026 · Jan 1, 2026

Lightspeed Venture Partners invests from seed through growth in enterprise, consumer, fintech and healthcare companies, with a global investment platform.

Its sector teams approach different company-building problems: enterprise adoption, changes in consumer behaviour, financial infrastructure and unmet clinical needs. The partnership includes former founders and operators with domain experience, so the relevant team depends on the business being built rather than a single firm-wide industry thesis.

Lightspeed’s healthcare practice focuses on technologies that can improve patient outcomes. In fintech, its stated interests span the financial technology stack, including blockchain, rather than being limited to consumer banking applications.
