Overview
Lambda is an AI-only infrastructure company founded in 2012 that provides NVIDIA-powered cloud GPUs, dedicated superclusters, managed orchestration, and AI-factory infrastructure for training and inference. Its primary product is the Lambda Superintelligence Cloud, spanning self-serve GPU instances through large single-tenant clusters and custom infrastructure for enterprises, hyperscalers, and frontier AI labs. Public evidence supports San Francisco roots and current operations/jobs in San Francisco, San Jose, and Bellevue; the work model appears flexible/hybrid with some remote roles. Lambda reports more than $1.5B in equity raised by November 2025, while public databases and announcements provide a partial funding history. No material layoffs, acquisitions, or shutdowns were identified in the reviewed sources; absence of evidence is not confirmation that none occurred. Website traffic and exact current headcount were not publicly established.
