Lambda

Lambda, previously called Lambda Labs, is an AI infrastructure company based in San Jose, California. The platform is built specifically to serve AI teams at every stage of development. Researchers and engineers use Lambda to prototype models on flexible on-demand compute, then scale those workloads to production-level infrastructure without needing to manage complex hardware. Its customers span universities, government agencies, and major enterprises, including Microsoft and Intel, with over 5,000 organizations relying on the platform.

Lambda focuses on two main product areas. Its public cloud gives users access to on-demand NVIDIA GPU instances like H100, H200, and B200, plus "1-Click Clusters" for quickly setting up multi-node systems with up to 512 GPUs. The private cloud offers dedicated, single-tenant GPU clusters for large training jobs.

Lambda was founded in 2012 and launched a facial recognition API for Google Glass the next year. Lambda shifted toward AI hardware and GPU infrastructure between 2017 and 2019, then opened its GPU cloud publicly in 2018, well ahead of the broader AI compute boom. Growth accelerated sharply after 2021 through a series of major funding rounds. By September 2025, Lambda had reached $303.3 million in annual revenue, up from a fraction of that just a few years earlier. The company achieved unicorn status in 2024.

Lambda has raised about $2.44 billion over ten funding rounds. In November 2025, its Series E round brought in $1.5 billion, led by TWG Global, the investment group of Thomas Tull and Mark Walter. Previous investors include NVIDIA, ARK Invest, Andra Capital, Mercato Partners, Bloomberg Beta, Gradient Ventures, and Andrej Karpathy. NVIDIA stands out as both an investor and a customer, agreeing to lease back 18,000 GPUs from Lambda in a $1.5 billion deal.
