Temporal Raises $300M Series D at $5B Valuation for Durable Workflow Execution Platform

Temporal Technologies announced on February 17, 2026 that it has raised $300 million in a Series D funding round led by Andreessen Horowitz, at a post-money valuation of $5 billion. Lightspeed Venture Partners and Sapphire Ventures co-led the round, with participation from existing investors including Sequoia Capital, Index Ventures, Tiger Global, GIC, Madrona, and Amplify Partners. The Bellevue, Washington-based company has now raised over $450 million in total.

What Temporal Does

Temporal provides an open-source durable execution platform — a programming model and runtime that allows developers to write long-running, stateful workflows in ordinary code without manually handling retries, timeouts, process crashes, or infrastructure failures. The core idea is that a Temporal workflow function continues executing correctly even if the underlying process, server, or network fails mid-execution, because the runtime persists execution state and replays it on recovery.

Organizations including OpenAI, Netflix, Snap, Datadog, Yum! Brands, and ADP use Temporal to orchestrate everything from CI/CD pipelines to financial transaction flows and, increasingly, multi-step AI agent workflows where reliable state management across potentially slow LLM calls is essential.

Growth Metrics

Temporal reported the following metrics alongside the funding announcement:

• 380% year-over-year revenue growth
• 350% increase in weekly active usage
• 500% increase in installations, now exceeding 20 million installs per month
• 9.1 trillion lifetime action executions on the Temporal Cloud product

The company will use the new capital to expand its cloud service globally, deepen integrations with AI development frameworks, and grow its enterprise sales and support organization. Temporal\'s open-source core (licensed under MIT) remains freely available, with Temporal Cloud providing the managed service.
