Temporal Raises $300M for AI Workflow Orchestration
Temporal, an open-source workflow orchestration platform, has raised $300 million in a Series D funding round at a $5 billion valuation. The company positions its platform as foundational infrastructure for ensuring reliability, observability, and auditability as enterprises deploy more complex and autonomous AI agents.
- The Series D round was led by Andreessen Horowitz, with Lightspeed Venture Partners and Sapphire Ventures also joining. Former VMware CEO Raghu Raghuram, now a general partner at Andreessen Horowitz, will join Temporal's board as an observer. - This round brings Temporal's total funding to $650 million. The company's previous capital raises include a $146 million Series C round in early 2025 and a $105 million secondary transaction in October 2025. - Co-founders Samar Abbas (CEO) and Maxim Fateev (CTO) have a long history with durable execution systems, having built five iterations of this technology at Amazon, Microsoft, and Uber before starting Temporal. - The open-source Temporal project is a fork of Cadence, a workflow engine the co-founders created and open-sourced while at Uber to manage microservices at scale. - The company reports significant growth, with a 380% year-over-year increase in revenue and a 500% rise in installations, now exceeding 20 million per month. - High-profile customers using the platform for production workloads include OpenAI, Netflix, Snap, and JPMorgan Chase. - Temporal's business model is built around its open-source software, which is licensed under the MIT license. The company generates revenue through its managed service offering, Temporal Cloud, which uses consumption-based pricing.
