Temporal is in discussions to secure $500 million at a valuation of $12 billion, which is double its valuation from February.

      Temporal Technologies is reportedly in discussions to secure approximately $500 million, according to Bloomberg on Tuesday. This funding round could value the software startup at $12 billion or higher prior to the new investment, as noted by sources familiar with the negotiations.

      The funding round has not yet been finalized, and the amount and conditions may vary, per Bloomberg. Temporal has not responded to the news agency's inquiries for comment.

      The anticipated valuation would more than double the $5 billion valuation the company achieved in February, when it raised $300 million in a round led by Andreessen Horowitz. If the new funding round is completed at the reported minimum, it would be the second instance this year that the company’s valuation has doubled.

      What Temporal Offers

      Temporal provides an open-source orchestration platform designed to operate beneath applications and ensure that multi-step processes do not fail midway. Established in 2019, the company offers its core platform under an open-source license and markets a managed version called Temporal Cloud.

      The concept predates the current surge in AI. Developers can write workflows using a standard programming language, while Temporal’s infrastructure captures each step. In the event of a service failure or connection loss, the workflow can continue from the last saved point instead of starting anew.

      The problem it addresses is a longstanding issue in software. For instance, a program might reserve a flight, update a database, and then notify a customer via email. Each of these actions needs to succeed, even if a server times out or a process fails mid-execution. Temporal claims its system manages this recovery, relieving developers from the need to set up their own timers, queues, and retry mechanisms.

      This service has gained significance as organizations implement AI agents, which execute extensive task sequences and may encounter silent failures en route. According to Temporal, its platform allows clients to keep agents operational over extended periods and helps trace workflow breakdowns while managing computing expenses. Notably, the company does not create or train AI models.

      Who Uses Temporal

      Temporal's largest client is OpenAI, as per the sources Bloomberg consulted. The news agency also reported that the startup collaborates with the AI coding company Replit and mentioned health-tech firm Abridge among its customers. Additionally, Temporal has identified Nordstrom, Block, ADP, and The Washington Post as clients.

      The company was co-founded by Samar Abbas and Maxim Fateev, who previously worked together on Amazon’s Simple Workflow Service and later at Uber, where they developed Cadence, an open-source workflow engine that became the technical precursor to Temporal. They launched Temporal in 2019 to offer a commercial solution based on their prior experiences.

      Both founders have extensive backgrounds addressing this category of issues prior to AI's popularity. Abbas led efforts on Microsoft’s Durable Task Framework, while Fateev contributed to key components of Amazon’s workflow and queue services. Their proposition is that maintaining reliable software through failures is a universal requirement, not specific to a particular model. Temporal doesn’t compete with its AI lab clients; rather, it provides an underlayer akin to what companies pay for databases or monitoring solutions.

      A Rapid Series of Funding Rounds

      The proposed financing would come after a swift series of fundraising efforts. Temporal announced a $146 million Series C round at a $1.72 billion valuation in March 2025, led by Tiger Global. The $300 million Series D round in February valued the company at $5 billion and was also led by Andreessen Horowitz, with contributions from Lightspeed Venture Partners and Sapphire Ventures. A finalized $500 million round would push Temporal’s total disclosed funding beyond $1 billion.

      Accompanying these funding rounds, Temporal has reported impressive growth metrics, claiming a year-on-year revenue increase exceeding 380 percent. As of February, its annual recurring revenue surpassed $100 million, and it previously noted more than 2,500 cloud customers. By this year, it indicated that monthly installations of its software had exceeded 20 million. These figures combine commercial revenue with free open-source usage, and Temporal has not publicly associated a current annual revenue figure with the proposed $12 billion valuation.

      A Competitive Landscape

      Temporal isn't the only company vying for market share. Cloudflare launched its Workflows product to general availability in April 2025, followed by Vercel, which introduced its own durable workflows in April 2026. Both integrate this feature into broader developer platforms. The startup Restate debuted a managed cloud service focusing on workflows and agents in September 2025.

      This fundraising effort occurs during a particularly active period for investments in AI infrastructure and applications. Legal-AI firm Harvey is raising funds at a valuation of $15.5 billion, while property-management startup EliseAI is discussing a $300 million fundraising at a valuation of $3.7 billion. Investors have been channeling funds into the foundational technologies supporting AI models, including data-center operations and tools that ensure AI agents remain operational.

      On Tuesday, the Amsterdam-based cloud provider Nebius announced it is raising $
