Gimlet Labs raises $80M for multi-silicon inference cloud
Gimlet Labs, founded by Stanford adjunct professor and founder Zain Asgar with cofounders Michelle Nguyen, Omid Azizi and Natalie Serrino, raised an $80 million Series A led by Menlo Ventures to commercialize what it calls a "multi-silicon inference cloud." The software orchestrates AI workloads across diverse hardware (CPUs, AI GPUs, high-memory systems), claims 3x–10x inference speedups for the same cost and power, and can slice models to run across different architectures. Gimlet has partnerships with chip makers NVIDIA, AMD, Intel, ARM, Cerebras and d‑Matrix, offers its product as software or via an API/Gimlet Cloud, and targets large model labs and data centers. The company reported eight-figure revenues at launch, has roughly 30 employees, and has now raised $92 million in total including prior seed and angel investments.
Gimlet Labs on Heterogeneous Inference for AI Agents
Gimlet Labs, a 2023-founded startup, builds software to orchestrate heterogeneous inference across multiple accelerator vendors for agentic AI workloads. The company operates a two-track model: deploying its orchestration software inside customer data centers (frontier labs, hyperscalers, sovereign clouds) while also operating its own mixed-silicon neocloud. Gimlet has raised $92M (Series A in March) and reports more than $10M in annualized revenue. Technically, Gimlet traces PyTorch workloads into graphs, splits them at optimal points, and lowers segments to vendor frameworks (e.g., TensorRT on NVIDIA). In a public example with d-Matrix, running a speculative decoder on a d-Matrix Corsair card while using NVIDIA B200s for verification delivered roughly a 4× shift in the throughput-vs-interactivity Pareto frontier on GPT-OSS 120B (8K/1K). Gimlet is hiring engineering roles in San Francisco.
a16z Announces Investment in Netris
Andreessen Horowitz (a16z) announced an investment in Netris, a startup that provides network management software for large GPU data centers. Netris' platform manages complex multi-network GPU clouds, installing agents on switches and offering automation, multi-tenancy, routing, load‑balancing, NAT, simulation and diagnostics. The firm has been building network management software for over eight years and is operating at scale across tens of thousands of GPUs. a16z cited the team's engineering strength—Alex Saroyan, Arsen Arakelyan and Tigran Martirosyan—as a key reason for the investment and framed Netris as addressing rising networking complexity in AI-focused data center architectures.
