Sim is an open-source AI workspace for teams that build, deploy and manage AI agents inside their organisations. Founded in 2025 and headquartered in San Francisco, California, the company sells a collaborative platform that connects hundreds of integrations and every major large language model, with centralised governance over access, spend, data and deployment. It reports more than 100,000 builders using the platform and raised $7M in a Series A round.
The Sim Platform offers several ways to construct agents. A drag-and-drop Workflow Canvas provides a visual builder; a conversational interface lets users assemble agents through chat; and a code and command-line route serves those who prefer to work programmatically. Supporting infrastructure includes self-hosting and containerisation options via Docker and Kubernetes, identity and access management through SSO and SCIM, and extensive API integration work. The company cites SOC 2 Type II, ISO 27001 and GDPR compliance among its enterprise security credentials.
The engineering work spans AI agents, large language models, workflow automation, open-source software, enterprise security and compliance, containerisation, identity management and API integrations. Industry verticals named include automotive and real estate. The company describes itself as built on an open-source ethos, with a collaborative platform designed for teams.
