Temporal is a Bellevue, Washington-based infrastructure software company whose open-source "durable execution" engine preserves application state, retries failed steps and keeps multi-step AI agents from crashing when external services fail.[1] Companies including OpenAI, NVIDIA, Netflix and JPMorgan Chase rely on its engine, according to GeekWire.[1] Temporal plans to use the money for platform R&D, developer and enterprise go-to-market teams and global cloud operations.[1]
Temporal says its annualized revenue run rate recently surpassed $250 million, growing over 200% year over year, and it doubled its workforce over the past year to 570 employees.[1]
Temporal is the open-source Durable Execution platform used to run AI agents; it raised a $550M Series E at $12.55B in Sept 2026, run rate above $250M.
Temporal is an open-source platform for building and running applications that keep working when parts of a system fail. Its core technology, Durable Execution, preserves application state so work can survive failures and finish reliably. Developers can use their preferred language and any models, tools or infrastructure, and the software is released under the MIT license.[1],[2]
Temporal sells a managed version of the software next to the free code. The company says developers can run open-source Temporal themselves or use Temporal Cloud, a fully managed service. Its September 2026 release says paying customers now exceed 4,300.[1]
Temporal's pitch for AI is that agent workflows have many steps and every step can fail.[1]
Temporal reports fast usage growth in its September 2026 release. Temporal Cloud processed more than 1.9 trillion actions in August, up more than 350% year over year, and open-source installs passed 43 million in August, up 134% since January 2026. These are company-reported figures, and the release does not define an install.[1]
Temporal grew out of workflow software that its two co-founders built at large companies. Maxim Fateev led development of Amazon's messaging infrastructure in 2004, which became the foundation for Amazon SQS, and the pair later launched the first public version of Amazon's Simple Workflow Service. Samar Abbas created the Azure Durable Task Framework at Microsoft. In 2015 they reunited at Uber to co-create Cadence, the workflow engine that preceded Temporal.[2],[3]
Temporal was founded in 2019 by Fateev and Abbas, after the success of Cadence at Uber prompted them to start a company around it. Its October 2020 release announced both the first production release of the software and an $18.75 million Series A. Users named in that release were Snap, Box, Coinbase and Checkr.[4],[3]
Temporal added a managed cloud product alongside the open-source project. The February 2023 Series B-Prime release said customers and revenues for Temporal Cloud had grown 20X in the year after the Series B, a company-reported figure with no base given. By March 2025 the company said Temporal Cloud had been adopted by over 2,500 customers.[5],[6]
Temporal's location is described differently across sources. The company's press releases carry Seattle datelines from 2020 through March 2025 and San Francisco datelines in 2026.[3],[6],[7],[1]

Lightspeed Venture Partners and Sapphire Ventures joined, with participation from insiders Sequoia Capital, Index, Tiger, GIC, Madrona and Amplify. In that release the company reported more than 380% year-over-year revenue growth, without giving a revenue base.[7],[1]
Temporal's Series C, announced on March 31, 2025, raised $146 million at a $1.72B post-money valuation and brought total funding to $350M. Tiger Global led, with participation from StepStone Group, Amplify Partners, Index Ventures, MongoDB Ventures, Sequoia Capital, Conversion Capital, Hanwha Next Generation Opportunity Fund and 137 Ventures.[6]

Index Venture Capital led a $100 million Series B on February 16, 2022, with a headline valuation above $1.5 billion. The $75 million Series B-Prime on February 28, 2023, added Greenoaks and took total funding past $200 million.[3],[4],[5]

Samar Abbas is co-founder and CEO of Temporal. The company's about page says he has 20 years of experience at AWS, Microsoft and Uber, worked on Amazon Simple Workflow Service from its inception, led development of the Durable Task Framework at Azure and co-created Cadence at Uber.[2]
Maxim Fateev is co-founder and CTO of Temporal. The about page says he spent eight and a half years at Amazon, where he led the architecture and development of AWS Simple Workflow Service and the storage backend for Simple Queue Service, and that he held engineering roles at Google and Microsoft.[2]
Temporal's founders have swapped titles over time. The October 2020 release named Fateev CEO and Abbas CTO, and the 2022 and 2023 releases quote Fateev as co-founder and CEO. By the March 2025 release Abbas was co-founder and CEO. The releases opened for this profile do not say when the change happened.[3],[4],[5],[6]
Temporal said in March 2025 that it had recently welcomed B2B software veteran Jim Cyb as President to lead go-to-market efforts. It also announced Sahir Azam, Chief Product Officer of MongoDB, as its first independent board member.[6]
Temporal named OpenAI, Snap, NVIDIA and Netflix as paying customers in its September 2026 release. The same release says Temporal supports critical applications at Anysphere (Cursor), Lovable, NVIDIA, Scale AI, Salesforce, Shopify, Netflix, Booking.com, Block and DoorDash. These are company statements.[1]
Temporal's 2022 Series B release said Netflix chose it as the foundation for its next-generation CI/CD system, which the release said would be used by almost every Netflix developer. That is the company's description. The release also listed Doordash, Snap, Box, Stripe, Hashicorp and Coinbase as users.[4]
Temporal lists integrations with OpenAI, Pydantic and Vercel. The February 2026 release names these partnerships and framework integrations as ways teams move from experimentation to production.[7]
Temporal became the front-of-shirt partner of Premier League club Crystal Palace in a multi-year agreement beginning with the 2026/27 season, announced on May 21, 2026. Temporal branding will appear across the men's and Academy teams, and the partnership will support community initiatives through the Palace for Life Foundation. The release gives no financial terms.[9]
