Temporal in Talks to Raise $500M at $12 Billion Valuation

Quick Facts

• Temporal Technologies is reportedly in talks to raise $500 million, which would value the company at more than $12 billion.
• The company’s revenue grew more than 380% in 2025, with annual recurring revenue passing $100 million as of February 2026.
• If closed, the round would push Temporal’s total announced funding past $1 billion and mark the second valuation doubling this year.

Temporal Technologies Inc. is in talks to raise approximately $500 million from investors, according to Bloomberg. The deal would value the application reliability startup at more than $12 billion, up from $5 billion in February 2026.

The round has not yet closed, and terms could change. Temporal did not respond to Bloomberg’s requests for comment.

The valuation jump reflects rapid growth. The company has seen its valuation grow more than fourfold in roughly 18 months, starting from a $1.72 billion valuation when it raised $146 million in the first quarter of 2025. A $105 million secondary deal in October 2025 pushed that figure to $2.5 billion. Then, in February 2026, Andreessen Horowitz led a $300 million Series D that doubled the valuation to $5 billion.

Revenue has kept pace. Temporal disclosed more than 380% revenue growth in 2025 and said annual recurring revenue crossed $100 million by February. The company reports more than 2,500 cloud customers and monthly software installations that have passed 20 million. Customers include OpenAI, Stripe, Netflix, Snap, Cloudflare, and Datadog, with more than 1,500 paying organizations running 130 billion monthly workflow actions.

Founded in 2019, Temporal builds open-source software and a managed cloud service centered on what it calls durable execution. Applications built on Temporal resume exactly where they stopped after a crash or failure, without engineers writing custom recovery logic. The company generates revenue through Temporal Cloud, a usage-based managed service, while the core software remains free.

CEO Samar Abbas and co-founder Maxim Fateev developed the underlying technology at Uber, where they built Cadence, the company’s open-source orchestration engine. Abbas also spent 11 years at Microsoft, where he created the Durable Task Framework for Azure, and later contributed to Amazon’s Simple Workflow Service.

Abbas has framed the company’s growth around the rise of AI agents. “Agentic AI doesn’t fail because the models aren’t good enough,” he said in February. “It fails because the systems around them can’t handle real-world execution.” He told GeekWire the company is “becoming the core piece of infrastructure which is powering the AI agentic wave.”

OpenAI’s VP of Application Infrastructure, Venkat Venkataramani, backed that view at the Replay 2026 conference. “Temporal’s durable orchestration framework is critical to handling our massive scale, complex agentic workflows, infrastructure control plane, and data pipelines,” he said.

Andreessen Horowitz has been direct about why it led the Series D. Partner Sarah Wang described reliability as a fundamental requirement for AI systems to function, calling Temporal the essential execution layer. The firm wrote in a blog post that as long-running agents drive enterprise value, “the execution layer beneath them becomes indispensable.”

The new capital, if raised, would go toward research, product development, and expanded sales and marketing. At Replay 2026, Abbas introduced two new products: Workflow Streams for real-time observability and Standalone Activities for durable job processing.

Temporal employed 552 people as of June 30, 2026. Raghu Raghuram, former VMware CEO and general partner at Andreessen Horowitz, joined the company as a board observer following the February round.

For software executives, the funding signals a broader shift. As AI systems move from generating text to running payroll, processing payments, or managing supply chains, infrastructure that guarantees fault tolerance and state management becomes a hard requirement. Temporal is one of the few companies positioned as that layer at scale.
