# Gimlet Labs $300M Series B for AI infrastructure

> Gimlet Labs has raised a $300 million Series B led by Andreessen Horowitz, vaulting the company to a $3 billion valuation and bringing its total funding to roughly $392 million. The startup is building what it calls a multi-silicon inference cloud, infrastructure designed to run AI models efficiently across many different types of chips rather than locking customers to one vendor's hardware. The technical hook is portability and speed. Gimlet claims up to 10 times the throughput by spreading inference across a mix of GPUs and specialized accelerators, and it says it tripled its customer base by March 2026. For companies deploying agentic AI, where models run constantly and compute bills balloon, squeezing more performance out of whatever silicon is available is a direct cost lever. The raise fits a clear pattern in this cycle. Investors are pouring money into the picks-and-shovels layer of AI, the plumbing that makes running models cheaper and faster, on the bet that as agents proliferate, efficient inference becomes one of the most valuable and defensible positions in the stack.
