Leadership Comments

With Gimlet, our customers are able to serve massive volumes of tokens at very low latency, even as their AI workloads continue to grow across all dimensions. We’re able to deliver unprecedented performance because Gimlet software intelligently slices and orchestrates their workloads across different types of hardware from both mainstream and emerging chipmakers,” said Zain Asgar, co-founder and CEO of Gimlet Labs.

Gimlet has built a new kind of inference cloud, heterogeneous by design, that matches each workload to the right silicon. By making GPUs and purpose-built accelerators work as one system, Gimlet delivers dramatically more throughput, more interactivity and more intelligence from every watt. We believe this is where inference infrastructure is headed,” said Raghu Raghuram, managing partner at Andreessen Horowitz and Gimlet Labs board member.
