Gimlet Labs Raises $300M at $3B Led by Andreessen Horowitz, With Arm and Microsoft's M12 Joining

Gimlet Labs, which builds software that splits AI inference workloads across different chip architectures (GPUs and SRAM-centric silicon), raised $300M at a $3B post-money valuation, six months after an $80M Series A at ~$400M. Andreessen Horowitz led, with Arm Holdings and Microsoft's M12 fund joining; Gimlet is collaborating with Arm to make its software compatible with more Arm chip variants.
