Temporal has raised $550 million in Series E funding at a $12.55 billion valuation as demand grows for infrastructure that can reliably run complex AI applications and long-running software workflows. Lightspeed Venture Partners led the round. Wellington Management, Growth Equity at Goldman Sachs Alternatives and Tiger Global served as co-leads, while T. Rowe Price and SV Angel also participated.
Existing investors including Andreessen Horowitz, Sequoia Capital, Index Ventures, GIC, Sapphire Ventures and Amplify also joined the financing.
The funding comes during a period of rapid growth for Temporal. The company’s annualized revenue run rate recently surpassed $250 million, representing growth of more than 200% year over year.
Net dollar retention has remained above 200% since February, indicating substantial expansion among existing customers.
Usage of Temporal Cloud has also increased sharply. The managed platform processed more than 1.9 trillion actions during August, up more than 350% from a year earlier.
Open-source Temporal installations surpassed 43 million in August, representing a 134% increase since January 2026.
Temporal now has more than 4,300 paying customers, including OpenAI, Snap, NVIDIA, Netflix and JPMorgan Chase.
Other organizations using the technology include Anysphere, the company behind Cursor, Lovable, Scale AI, Salesforce, Shopify, Booking.com, Block and DoorDash. Applications range from long-running AI agents and autonomous-vehicle simulations to payments and customer operations.
Temporal’s core technology, Durable Execution, is designed to preserve application state so workflows can survive failures and continue from where they left off rather than restarting from the beginning.
The architecture is particularly relevant to agentic AI applications, where a single workflow may involve numerous models, tools, APIs and external systems and can run for extended periods. Temporal is designed to maintain the state of that work when individual components fail.
Developers can use Temporal with their preferred programming languages, AI models, tools and infrastructure. They can deploy the open-source version themselves or use Temporal Cloud as a fully managed service.
Temporal Cloud is used by more than 4,000 customers, including OpenAI, Cursor, Netflix and JPMorgan Chase.
The company sees growing demand as enterprises move AI agents from demonstrations and experimental environments into production systems where reliability becomes increasingly important.
As agents perform more steps across multiple systems, Temporal argues that the number of potential failure points rises significantly, increasing the need for infrastructure capable of preserving state and ensuring workflows ultimately complete.
The company plans to use the new capital to deepen research and development across its platform, expand its developer and enterprise go-to-market operations and scale the teams and infrastructure supporting its next stage of growth.
Temporal will also continue expanding internationally to address global demand.
The company’s workforce has doubled during the past year to approximately 570 employees. The Series E adds several large institutional investors to its shareholder base, including Wellington Management, Growth Equity at Goldman Sachs Alternatives and T. Rowe Price.
KEY QUOTES:
“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. Temporal was built for this problem. Durable Execution is becoming the standard for reliable applications at scale, and this investment reflects the conviction that much of the next generation of software will be built on Temporal.”
Samar Abbas, Co-Founder and CEO of Temporal Technologies
“Every team building on AI hits the same wall: the demo is easy, production is hard, because the systems around the models can’t handle real-world execution. Most of the market solves that by locking teams into a proprietary stack. Temporal is the open, pluggable foundation that runs their agents and the systems they already depend on, and it’s becoming one of the most important pieces of infrastructure in the agentic era.”
