**TraceOpt**, operating as OptAI UG (haftungsbeschränkt), develops an open-source tool called TraceML that provides real-time visibility into GPU memory usage, training time, and layer-level performance for PyTorch models. The product targets ML engineers, researchers, and small ML teams running training workloads to identify performance bottlenecks and training costs. It functions as a lightweight observability layer without requiring heavy profilers or complex setup. Abhinav Srivastav serves as CEO. The company maintains its registered address at Kolonnenstraße 8, Berlin, 10827, Germany. No funding rounds or revenue have been recorded. A GitHub discussion from the TraceML repository seeks a founding engineer on a co-founder track.
