Harmonic Tech Stack

AI mathematical reasoning engine built on formal verification and theorem proving

Software Development Palo Alto, CA 11–50 employees Privately Held

Harmonic is a Palo Alto startup building an AI system for mathematical reasoning, with proof assistants Coq and Agda sitting alongside PyTorch, JAX, CUDA, Triton and NCCL in its stack. That pairing, plus Slurm, Kubeflow and multi-cloud AWS/Azure/GCP, points to large-scale reinforcement learning over formal proofs. Accelerating, engineering-led hiring centers on RL throughput, inference latency and turning research into product.
