# Inngest

> Inngest is a durable execution platform that gives developers reliable background jobs, workflows, and AI-agent orchestration without managing queues or infrastructure. Founded in 2021 by Tony Holdstock-Brown and Dan Farrelly, the San Francisco company combines event streams, queues, and durable step functions into SDKs for TypeScript, Python, and Go, plus AgentKit for multi-agent systems. It has raised roughly $30 million, most recently a $21M Series A led by Altimeter in 2025, and processes over 100 million executions a day for teams including SoundCloud, Resend, and Replit.

- **Flow Control** — Concurrency limits, multi-tenant fairness, rate limiting, throttling, debouncing, prioritization, and event batching built into functions.
- **SDKs (TypeScript, Python, Go)** — Language SDKs that let functions run over HTTP on any host, with cross-language invocation and live language migrations.
- **Replay & Observability** — Real-time metrics, tracing, and Replay tooling to recover and re-run failed workflows after shipping a fix.
- **AgentKit** — TypeScript framework for building multi-agent networks with deterministic routing, shared state, and MCP tooling across OpenAI, Anthropic, and Gemini models.
