As answered by people managing Overmind and Humanloop.
Overmind's answer
Overmind covers the whole path from production traces to a model you own on one open-source platform. It ingests your agent's OpenTelemetry traces, turns them into training datasets with provenance back to each trace, scores changes with your own evaluators, and fine-tunes and serves a smaller open-weight model. The trained weights are downloadable, so the model is yours.
Overmind's answer
Overmind goes past tracing and evals. It uses the same traces and evaluators to train and serve a specialised model, so you can benchmark it against the model you run today and switch only when it wins. The platform is AGPL-3.0 and self-hostable with Docker Compose, it imports existing data from Langfuse, LangSmith, Braintrust and Galileo, and the hosted version has a free plan.
Overmind's answer
AI product teams with an LLM agent already in production on frontier APIs. The typical user is an agent engineer, ML engineer or technical founder who wants better quality, lower inference cost, and a model the company owns.
Overmind's answer
Overmind's mission is to turn every company into a frontier lab. Every team can call the same frontier API, so the edge comes from the data only you have: your production traces. Overmind was built to turn that data into a specialised model each team owns, trained, benchmarked and served from one place. The company is based in the United Kingdom, founded by Tyler Edwards (CEO) and Sam Brunt (COO), and backed by 14 Peaks Capital, Antler, Osney Capital, Portfolio Ventures and Endurance Ventures.
