Fixie
Cloud platform for building, hosting, and scaling natural-language AI agents.
About
Fixie is a cloud-hosted platform for building LLM-powered agents that connect to enterprise data, systems, and workflows. Developers wrap a data source or API in a small amount of code, hook it up to a large language model of their choice, and the resulting agent translates English queries from end users or other agents into calls to that external system.
Founded in Seattle in 2022 by Matt Welsh, Justin Uberti, Zach Koch, and Hessam Bagherinezhad, Fixie raised 17 million dollars in seed funding led by Redpoint Ventures. The platform ships with more than 30 built-in agents covering databases, GitHub, Google Calendar, web search, and social data, and the Fixie Agent SDK deploys new agents to the cloud in a single click.
