Lightspeed Venture Partners is a global multi-stage venture firm founded in 2000 that manages more than US$40B. It closed a record US$9B across six vehicles in December 2025, explicitly structured to fund capital-intensive AI, and led Anthropic's US$3.5B Series E. Its AI portfolio spans frontier labs, infrastructure and AI-native applications.
Lightspeed's thesis is that AI value concentrates in companies that need sustained, enormous capital for talent, compute and infrastructure — so it raised a record US$9B across vehicles that separate early-stage risk from growth-stage follow-on. Opportunity Fund III (US$3.3B) exists to keep backing winners from Series C through E+ instead of losing them to later-stage funds.
The firm prides itself on staying with founders from Seed to Series F and beyond. Its Anthropic arc is the clearest example: engagement before public product, Series D in early 2024, leading the US$3.5B Series E in 2025, Series F — then seeking ~US$600M more via a Project Mercury continuation vehicle (2026) to extend ownership of OpenAI and four other assets while adding fresh Anthropic exposure.
Rather than a single global platform, Lightspeed runs local-first partnerships (US/EU/Israel as LSVP; India/SEA as LSIP) that act as 'first investor and early backer' in each region — a structure that lets it be the seed lead for Mistral in Paris and a growth lead for Indian and Israeli AI companies at the same time.
Its portfolio spans frontier labs (Anthropic, OpenAI, xAI, Mistral, Reflection AI), infrastructure and data (Databricks, Glean), and vertical applications (Abridge, Skild AI, Verkada, Rippling) — with consumer, healthcare and fintech teams realigned around AI-native opportunities.
Lightspeed operates as a federated set of regionally anchored entities — Lightspeed Management Company across the US, Europe and Israel, and Lightspeed India/SEA separately — with offices spanning Menlo Park, San Francisco, New York, Tel Aviv, London, Paris, Berlin, India and Singapore. The firm began investing in AI in 2012 and says it has since backed 165 AI-native companies with more than US$5.5B committed. It was founded by Barry Eggers, Christopher Schaepe, Ravi Mhatre and Peter Nieh.

Because AI capital intensity breaks the single-fund model. The December 2025 close — its largest ever — separates early-stage risk (two funds totalling US$2.18B) from growth follow-on (Opportunity Fund III, US$3.3B), plus a US$600M co-investment vehicle and US$1.25B in single-investor mandates. The segmentation exists so winners from Series C onward get re-backed internally instead of being handed to later-stage funds.
A continuation vehicle: in 2026 Lightspeed sought ~US$600M more to extend its ownership of OpenAI and four other assets while adding fresh Anthropic exposure. Continuation structures let a firm keep positions its existing fund lives cannot hold — a structural answer to AI winners outgrowing the vehicles that backed them, with Verkada and Rippling from the same book inside it.
In stage depth: engagement before public product, Series D in early 2024, then leading the US$3.5B Series E in 2025, returning for Series F, with a reported ~US$1B cheque among the largest written by any VC in the sector. Menlo led the prior Series D; Sequoia first entered in 2026 — Lightspeed's claim is the longest run of consecutive institutional rounds across the lab's growth phase.
Local-first by design: Lightspeed Management Company across the US, Europe and Israel, and Lightspeed India/SEA as a separate entity, each acting as 'first investor and early backer' in its region. The structure lets the same franchise be Mistral's Paris seed lead and a growth lead for Indian and Israeli AI at the same time — the opposite organizing principle from a16z's single global platform.
Depends on the metric. Lightspeed was the 2023 seed lead and has backed every round through Series D — its page calls it the longest continuous run of any Mistral investor. Index wrote the first institutional cheque before incorporation and has also participated in every round, including the €3B Series D. Two overlapping arcs since 2023; the lab concentrated its earliest believers unusually densely.
