Luminal: Revolutionizing AI Infrastructure with Compiler-Driven GPU Optimization

We’re thrilled to announce our partnership with Luminal, an extraordinary team that we believe will redefine AI infrastructure.

AI is transforming the world at a staggering pace, but under the hood, one thing hasn’t kept up: how inefficiently we use GPUs. Most companies achieve just 10–20% GPU utilization. The rest goes to waste, amounting to billions of dollars in idle compute. Or as the Luminal founders describe it, “Most people running their own AI models are lighting money on fire and don’t even know it.”

They’re building Luminal to change that. Luminal’s compiler technology takes PyTorch models and automatically compiles them into highly optimized GPU code, boosting GPU utilization to over 80% while preserving the familiar developer workflow. And with Luminal's serverless Cloud, engineers can push a model to production with a single command. It’s effortless, scalable, and hardware-agnostic.

At the heart of Luminal is a founding team with rare, end-to-end mastery of the AI infrastructure stack. CEO Joe Fioti designed AI accelerators at Intel, becoming an expert on how AI workloads actually interact with chips. CTO Matthew Gunton built global-scale infrastructure at Amazon, developing self-healing systems that powered Amazon’s global inventory network. And COO Jake Stevens brings a rare mix of technical and operational experience from both Apple and scaling his last startup. 

The opportunity they’ve tapped into is enormous. Luminal estimates that neocloud GPU consumption alone will exceed $17 billion annually and grow 30-40% each year. Luminal addresses a systemic inefficiency that impacts every AI company, from startups to hyperscalers. As workloads become increasingly multimodal and compute-hungry, demand for Luminal’s infrastructure optimization will only accelerate. Beyond immediate gains in deployment efficiency, Luminal’s hardware-agnostic compiler positions it as a neutral optimization layer, accelerating inference on popular GPUs and unlocking alternative architectures.

Joe, Matthew, and Jake are building the missing optimization layer between the world’s most powerful chips and the models that depend on them. If they succeed, Luminal won’t just make AI chips more efficient — it will redefine how AI applications are deployed altogether.

We’re thrilled to partner with the Luminal team as they bring this vision to life.
