Temporal, the open-source platform which powers world's most capable AI applications, today announced $550M Series E raise at valuation of $12.55B. The round was led by Lightspeed. Co-leads include Wellington Management, Growth Equity at Goldman Sachs Alternatives, and Tiger Global, as well as strong participation from T. Rowe Price and SV Angel, widening group of investors supporting Temporal's global growth. Returning investors include a16z, Sequoia, Index, GIC, Sapphire Ventures, and Amplify.
Led by Lightspeed, round backs Temporal as platform companies depend on to keep critical work running, from payments to agentic AI.
"As agents take on more critical work across more systems, every additional step creates another place to fail. In production, that work has to survive those failures and finish reliably," said Samar Abbas, co-founder and CEO of Temporal Technologies. "Temporal was built for this problem. Durable Execution is becoming standard for reliable applications at scale, and this investment reflects conviction that much of next generation of software will be built on Temporal."
"Every team building on AI hits same wall: demo is easy, production is hard, because systems around models can't handle real-world execution," said Anoushka Vaswani, Partner at Lightspeed Venture Partners. "Most of market solves that by locking teams into proprietary stack. Temporal is open, pluggable foundation that runs their agents and systems they already depend on, and it's becoming one of most important pieces of infrastructure in agentic era."
The proof is in how customers adopt Temporal, expand its use, and run it at scale. From long-running agents and autonomous-vehicle simulations to payments and customer operations, Temporal supports critical applications at Anysphere (Cursor), Lovable, NVIDIA, Scale AI, Salesforce, Shopify, Netflix, Booking.com, JPMorgan Chase, Block, DoorDash, and thousands more.
With new funding, Temporal will expand global operations to meet worldwide demand, building on team that has doubled to 570 employees over past year. Temporal will use funding to deepen platform R&D, grow developer and enterprise go-to-market, and scale teams and infrastructure behind next phase of growth.
