What Expected Parrot does
Expected Parrot helps companies simulate their customers with AI agents to explore pricing, product, marketing, communications and other scenarios at scale. Our open-source library and no-code web app let you design custom agent personas and conduct interviews and surveys with them using LLMs of your choice to generate results and reports. Everything is cached and reproducible, and you can send the same surveys to human respondents to validate results in the same interface.

Simulate your customers with AI agents
We build a platform that lets companies simulate their customers using AI agents. Users create custom agent personas via an open-source library or a no-code web app, then run interviews and surveys with these agents using large language models they choose. This helps companies test pricing, marketing, and product ideas at scale. Everything is cached for reproducibility, and users can run the same surveys with real humans for comparison in one interface.
We live in Cambridge, MA, USA and plan to keep the company headquartered here after YC.
We're based in Cambridge because of the tech talent here and proximity to early enterprise users. Staying here after YC lets us continue building relationships and grow the team locally.
