Humanloop

London · founded 2020

Humanloop was one of the first developer platforms for building on large language models — prompt management, evaluation and observability for LLM applications, pitched as 'the LLM evals platform for enterprises'. In 2025 the team joined Anthropic and the standalone product is being wound down; the homepage is now just the acquisition announcement, so as an independent company with its own benefits it effectively no longer exists.
