$9B to back category-defining AI companies
Lightspeed closed over $9 billion in committed capital across six funds in December 2025, positioning itself as a predominantly AI-focused investor. The firm has backed 165 AI-native companies including Anthropic, xAI, Databricks, Mistral, Glean, Abridge, and Skild AI.
Lightspeed's core thesis: AI is an unprecedented source of value creation, reshaping industries even faster than the platform shifts of internet, mobile, and cloud computing. The firm believes compounding progress in AI will drive profound shifts in professional services, scientific discovery, and autonomy markets in 2026.
Lightspeed has backed 165 AI-native companies. The firm's center of gravity is depth—building and maintaining mastery that enables unwavering conviction in the companies they back.
AI will drive profound shifts in professional services—legal, accounting, consulting, and other knowledge work that has historically resisted automation.
AI is accelerating scientific discovery in ways that weren't possible before. Drug discovery, materials science, and fundamental research are all being transformed.
Autonomous systems—vehicles, drones, robots—are reaching the capability threshold where deployment at scale becomes possible.
