Bellevue-based Temporal, an open-source platform for agentic applications, has raised its valuation to $5 billion following its latest funding round. The $300 million Series D raise from investors including a16z, Lightspeed Venture Partners and Sapphire Ventures comes nearly a year after the company’s Series C.
Temporal’s solutions are designed to address the gap between agentic AI experimentation and adoption by providing a durable execution layer for long-running systems. Companies use Temporal’s tech to run agents that execute for weeks at a time, control infrastructure costs amid scaling AI workloads, expedite product delivery and improve agentic loop observability.
The company has recorded significant growth over the past year with a 380 percent increase in revenue and a 350 percent increase in weekly active usage. Temporal’s platform now exceeds 20 million installs per month, serving customers like OpenAI, Block, Nordstrom and The Washington Post.
“Agentic AI doesn’t fail because the models aren’t good enough. It fails because the systems around them can’t handle real-world execution. And rather than create new problems, agentic AI tends to expose old ones such as managing state and failures,” Samar Abbas, Temporal CEO and co-founder, said in a statement. “We’ve been solving these same problems for years. Temporal exists to make agentic AI work in production as well as any other class of application, reliably, predictably and at scale.
With the help of its new capital, Temporal plans to further invest in open-source technology, expand its cloud platform and extend its solution to more companies.
