PromptLayer

Prompt management platform letting non-engineers edit, version, and deploy production prompts alongside engineering evals.

PromptLayer started as a logging wrapper around the OpenAI API, letting its founders replay and search their own GPT requests while building other projects in 2021. It grew into a broader prompt-CMS: a place where prompts live outside application code, get versioned like any other artifact, and can be edited and deployed by product managers or domain experts without opening a pull request. Based in New York City, the company was founded in 2021 by Jared Zoneraich and Jonathan Pedoeem and has raised a $4.8 million seed round, with backing from investors including engineers and operators from Anthropic, OpenAI, and Amazon. Zoneraich serves as CEO with Pedoeem as co-founder. The product has positioned itself as the layer non-technical teammates actually touch, while engineers keep ownership of evaluation harnesses and observability underneath. It's often the first tool a small team adopts before graduating to something like Langfuse once they need self-hosting or deeper observability, a reputation the company leans into by keeping onboarding fast.
