Temporal raises $550M at $12.55B on agent durability demand, reporting 1.9 trillion billable actions in August and 4,300+ paying customers
Temporal announced a $550M Series E on September 14 at a $12.55B valuation, led by Lightspeed and Wellington with Goldman Sachs Alternatives, Tiger Global and T. Rowe Price participating. The post frames the raise around agents that run for days or weeks and need to survive outages and approval waits without hand-built recovery machinery. Reported numbers: 1.9 trillion billable actions processed in August (up 350%+ YoY), 43 million open source installs (up 134% since December 2025), 4,300+ paying customers (up 139% YoY), net dollar retention above 200%, with OpenAI, Snap, NVIDIA and JPMorgan Chase named as customers.
