the agent reliability layer just got a $12.55b price tag. temporal raised $550m on sept 14, doubling its valuation in seven months, with annualized revenue past $250m for the durable execution engine that keeps long-running agents alive across failures.
workflow orchestration is now core agent infrastructure.
Context
Temporal's post of 14 September 2026 announces a 550 million dollar Series E at a 12.55 billion dollar valuation, co-led by Lightspeed with Wellington, Goldman Sachs Alternatives, Tiger Global, T. Rowe Price and SV Angel, with returning investors including a16z, Sequoia, Index and GIC. It reports, as company figures, annualized revenue run rate up more than 200 percent year over year, net dollar retention above 200 percent since February, 1.9 trillion billable actions in August, 43 million open-source installs and more than 4,300 paying customers. Reuters coverage of the same date was seen as a snippet.
The raise and the valuation are separate numbers, and 12.55 billion is the company's valuation and not a price tag on an agent reliability layer; Temporal's post also frames durable execution for payments and enterprise systems. The doubling in seven months and annualized revenue past 250 million are not in the text read, which gives growth percentages only; they are unverified here. Growth figures are company-reported. That workflow orchestration is core agent infrastructure is the author's thesis.
