Company Description

Lambda is an artificial intelligence infrastructure company that provides large-scale cloud computing resources for AI training and inference. The company develops and operates what it calls "AI Factories," which are data centers equipped with thousands of high-performance NVIDIA GPUs. Its offerings include GPU cloud access, dedicated clusters, servers, and workstations pre-configured with machine learning frameworks. Founded in 2012 and formerly known as Lambda Labs, the California-based company has grown to approximately 600 employees. It has evolved from its origins to become a provider of distributed AI infrastructure for enterprises in sectors such as technology and pharmaceuticals.

The company is focused on expanding its AI infrastructure and investing in sustainable technology. A recent development includes the launch of hydrogen-powered NVIDIA GPU systems, designed to enable AI training with zero emissions and no water usage. Lambda is also expanding its physical footprint with projects like a new AI cluster in Ohio featuring thousands of NVIDIA B200 GPUs. The company's growth is supported by significant capital, having raised a total of $1.65 billion. This includes a recent funding round of $480 million backed by Nvidia in early 2025, reflecting the high demand for specialized AI computing power.
