Lambda, a San Francisco, CA-based company developing an AI cloud platform, raised $480M in Series D funding.
The round was led by Andra Capital and SGW with participation from new investors Andrej Karpathy, ARK Invest, Fincadia Advisors, G Squared, In-Q-Tel (IQT), KHK & Partners, and NVIDIA, among others, as well as strategic investment from Pegatron, Supermicro, Wistron, and Wiwynn, as well as many existing investors including 1517, Crescent Cove, and USIT.
The company intends to use the funds to accelerate the expansion of the Cloud platform, its Model Inference API, and Chat AI Assistant.
Led by CEO Stephen Balaban, Lambda provides infrastructure, cloud services and software for the fine-tuning, training, and inferencing of AI models. The company launched a self-serve and on-demand GPU clusters for AI model training: 1-Click Clusters. Leveraging Lambda’s base of owned compute infrastructure, the company has introduced the Lambda Inference API and Lambda Chat AI Assistant, offering hosted access to open source models like DeepSeek R1.
The news followed a funding announcement in April.
