Temporal company profile: valuation, funding & revenue

This Temporal company profile covers the company's valuation, revenue, funding rounds, investors and history. Temporal works in developer tools, with a focus on durable execution and workflow orchestration. It was founded in 2019 and is headquartered in Seattle, Washington, United States. Its latest valuation on record is US$12.55 billion (post-money, reported) (September 2026). Every figure links to a public source, and anything the company hasn't disclosed is marked as such.

Overview

Temporal makes software that guarantees code runs to completion, even when servers crash, networks fail or tasks take hours, days or months. Developers write their business logic, such as processing a payment, provisioning cloud infrastructure, running a loan application or orchestrating an AI agent's multi-step task, as ordinary code, and Temporal automatically records progress, retries failed steps and resumes exactly where it left off after any failure. This approach, called durable execution, removes a huge amount of complex error-handling code that engineers would otherwise write themselves. Temporal's open-source platform is used by thousands of companies, and its managed service, Temporal Cloud, has grown rapidly as AI agents create new demand for reliable long-running workflows.

Samar Abbas, the CEO, and Maxim Fateev founded Temporal in 2019. Together they created Cadence, an open-source workflow engine, at Uber, and before that Fateev led development of Amazon's Simple Workflow Service and Abbas worked on Microsoft's Azure Durable Task Framework. Temporal began as a fork of Cadence. The company is based in the Seattle area.

What durable execution solves

Distributed systems fail constantly in small ways: a service times out, a server restarts during a deployment, an external API returns an error. When a business process spans many steps and services, engineers must handle every possible failure, track state in databases and build retry logic, queues and timers. This code is hard to write, test and maintain, and bugs can lead to double charges, lost orders or stuck processes. Temporal handles these concerns in its platform, so developers can write workflows as if failures didn't exist, with the confidence that every step will complete or be compensated correctly.

Products

• Temporal open source: the server and SDKs for Go, Java, TypeScript, Python, .NET, PHP and Ruby, free to self-host.
• Temporal Cloud: a fully managed service with high availability, security and global regions.
• AI agent support: patterns and integrations for running AI agents and long-running AI pipelines reliably, including human approval steps.
• Nexus: features for connecting workflows across teams and services.

Funding

Temporal raised early funding from Amplify Partners, Sequoia Capital and Index Ventures. In March 2025 it raised a US$146 million Series C at about US$1.72 billion, led by Tiger Global. In February 2026 it raised a US$300 million Series D at a US$5 billion valuation, led by Andreessen Horowitz, with Lightspeed Venture Partners and Sapphire Ventures joining existing investors including Sequoia, Index and Tiger Global. Later in 2026, Bloomberg reported that Temporal was in talks to raise about US$500 million at a pre-money valuation of at least US$12 billion. We haven't seen that round confirmed, so we use the February 2026 figure.

Business model

Temporal earns revenue mainly from Temporal Cloud, priced by usage measured in actions (workflow steps and events), storage and support levels. Many companies start with the free open-source version and move to the cloud service to avoid operating it themselves. The company doesn't publish revenue, so we show it as not disclosed.

Competition

Temporal competes with workflow and orchestration tools such as AWS Step Functions, Azure Durable Functions, Netflix's Conductor (Orkes), Inngest, Restate and Apache Airflow (for data pipelines), and with in-house systems built on queues and databases. Its advantages are its battle-tested design, multi-language SDKs, strong open-source community and adoption by demanding companies in finance, technology and AI.

Temporal at a glance

Temporal is a Seattle-area developer infrastructure company founded in 2019 by Samar Abbas and Maxim Fateev, creators of Uber's Cadence. Its durable execution platform makes long-running code reliable and is increasingly used for AI agents. It raised US$146 million at about US$1.72 billion in March 2025 and US$300 million at US$5 billion in February 2026, led by Andreessen Horowitz, then a reported US$550 million Series E at US$12.55 billion in September 2026.

Timeline

• 2015–2017: founders create Cadence at Uber.
• 2019: found Temporal and fork Cadence.
• 2020–2022: raise Series A and B; launch Temporal Cloud.
• March 2025: raises US$146 million at about US$1.72 billion.
• February 2026: raises US$300 million at US$5 billion.
• September 2026: reported US$550 million Series E at US$12.55 billion, co-led by Lightspeed and Wellington.

Why AI agents need durable execution

AI agents perform tasks that involve many steps: calling models, using tools, waiting for external systems, asking humans for approval and handling errors. A single agent task can run for minutes or days and may fail at any point because of model timeouts, rate limits or API errors. Without durable execution, a failure can mean restarting the whole task, losing work or repeating actions such as sending an email twice. Temporal lets developers build agents whose progress survives failures, which is why AI companies have become an important source of growth and why investors have raised its valuation quickly.

Who uses Temporal

Temporal is used by technology companies, banks, insurers, retailers and AI companies for payment processing, order fulfilment, infrastructure automation, data pipelines, customer onboarding and AI agent orchestration. Its users are mainly backend and platform engineers.

Risks

• Cloud provider competition: AWS, Azure and Google offer their own workflow services.
• Open-source cannibalisation: companies may self-host rather than pay for the cloud service.
• Valuation expectations: a rapidly rising valuation assumes sustained AI-driven growth.

Questions for engineering teams

• Which workflows in your systems fail in ways that cause costly errors?
• Should you self-host or use the managed cloud?
• Which languages and frameworks do your teams use?

Latest developments (October 2026)

Temporal's valuation more than doubled in 2026. After a US$300 million Series D at US$5 billion earlier in the year, it raised a US$550 million Series E at a US$12.55 billion post-money valuation in September 2026, co-led by Lightspeed and Wellington Management, according to AlphaMaven. The company said annualised revenue had passed US$250 million, more than tripling in a year, as AI agent builders adopt its durable execution software. See our developer tools guide.

Takeaways

Engineering teams can make long-running processes and AI agents reliable with less code. Founders can see how open-source infrastructure built at a big tech company becomes a startup. Investors should separate the confirmed US$5 billion round from reported higher talks.
