Lambda (also known as Lambda Labs) is an AI infrastructure company focused exclusively on GPU-based compute for training and running advanced machine learning models. Rather than offering general-purpose cloud services, Lambda provides an “AI developer cloud” – high-performance GPU clusters, private superclusters, and on-prem systems optimized for deep learning workloads. The company’s platform is used by AI startups, research labs, and enterprises that need large-scale training and fine-tuning capacity without building their own data centers.
Founded in 2012 and headquartered in San Jose, California, Lambda has evolved from selling pre-configured GPU workstations to operating hyperscale “AI factories” – data centers built around thousands of NVIDIA GPUs wired with high-speed networking. In 2025, Lambda raised over $1.5B in a Series E round led by TWG Global to expand its “Superintelligence Cloud” footprint and build gigawatt-scale AI infrastructure, alongside a multibillion-dollar agreement with Microsoft to deploy tens of thousands of NVIDIA GPUs.
Lambda positions itself as a specialized alternative to the major hyperscalers (AWS, Azure, Google Cloud), emphasizing transparent pricing, developer-focused tooling, and cost-efficient GPU access. Third-party research indicates the company crossed a ~$500M revenue run-rate in mid-2025 and is one of the faster-growing players in the GPU cloud market as demand for AI compute continues to expand.
