Temporal reports rapid growth across its platform: annualized revenue run rate above $250 million with over 200% year-over-year growth, more than 4,300 paying customers, and over 1.9 trillion billable actions processed in August.

Open-source adoption remains strong, with more than 43 million installs as of August, up about 134% since January, and over 368,000 actions in August year over year growth highlighting broad developer engagement.

Co-founder and CEO Samar Abbas and Lightspeed partner Anoushka Vaswani emphasize durable, open, and pluggable infrastructure as essential for modern AI systems.

Temporal hosted its fifth Replay conference at Moscone Center in 2026, while expanding sponsorships and signaling plans for deeper enterprise investment, global expansion, another Replay event, and continued platform development.

The company positions its Durable Execution technology as the backbone for reliable, scalable AI applications and agent-based workloads in production.

Founders Abbas and Fateev bring experience from Amazon, Microsoft, and Uber (Cadence), leading Temporal to become a standalone open-source platform after leaving Uber in 2019.

This Series E follows a February 2026 Series D of $300 million at a $5 billion post-money, with participation from major investors; a notable board observer joined during that round.

Temporal plans to broaden developer and enterprise go-to-market efforts and scale infrastructure, supported by a diverse group of returning and new institutional investors.

Major customers include OpenAI, Snap, NVIDIA, Netflix, and JPMorgan Chase, underscoring broad enterprise adoption across AI and software applications.

OpenAI reports a 60-fold usage increase in under a year and highlights Durable Execution as critical for reliable AI systems.

Leadership updates include OpenAI Agents SDK general availability and a Vercel AI SDK integration for durable TypeScript development, alongside promotions and a new VP of Product Marketing.

Funding will fuel global expansion, core platform development, and reliability and security enhancements, with Temporal’s headcount nearing 570 as the team continues to grow.
