About the Company

Sim.ai is the fastest-growing platform to build AI agent workflows. We're open source with 26k stars in the last 8 months.

Tech Stack

At Sim, our stack sits at the frontier of AI: multi-agent orchestration, MCPs, advanced LLM capabilities, browser agents, and more. We’re constantly working to translate the latest advances from AI research labs into a platform that builders can use to create powerful AI agents. This means solving challenging problems in orchestration, reliability, and scale while pushing the boundaries of what AI agents can actually do in real-world environments.
