Temporal Technologies

Provides durable execution infrastructure that ensures AI agent workflows are resilient to failures, with automatic retries, state persistence, and human-in-the-loop orchestration for production-grade agents. OpenAI Agents SDK now pairs with Temporal; launched Durable AI Agents Bundle; Ruby SDK GA in 2025; key infrastructure for production-grade agentic workflows; strong enterprise adoption.

Durable execution solves the core reliability gap that makes AI agents flaky in production — used by NVIDIA, ZoomInfo, and Gorgias to run agents at enterprise scale.

Founder backgrounds

Maxim Fateev

Co-Founder & Chief Technology Officer

Previously a principal engineer at AWS, where he was the tech lead for the Simple Workflow Service (SWF) and contributed to the SQS replicated message store. Before AWS, he held engineering roles at Microsoft and Google. At Uber, he co-created **Cadence**, a workflow orchestration engine that became Temporal's direct predecessor. He holds a Master's in Computer Science from the Federal University of Rio de Janeiro and a degree in Physics from Lomonosov Moscow State University. He co-founded Temporal in 2019 alongside Samar Abbas, forking Cadence to build an open-source durable execution platform — a concept he has now iterated on across three different companies over more than a decade.

Samar Abbas

Co-Founder & Chief Executive Officer

Co-founded Temporal in 2019 with Maxim Fateev, the culmination of a decade-long partnership spanning AWS, Microsoft, and Uber where they iterated on the same core orchestration concept. At Uber, Abbas helped architect Cadence, the open-source microservices orchestration engine that directly preceded Temporal. Earlier, at Microsoft, he built the Azure Durable Task Framework. He previously held senior engineering roles at Amazon and Microsoft before serving as CTO at Temporal and later stepping into the CEO role. The company, now valued at $5B, provides durable execution infrastructure that has become foundational for production-grade AI agent workflows.

AI bull / bear

Bull case

Temporal is cementing itself as the reliability backbone for the agent economy. The OpenAI Agents SDK integration is a watershed moment — it positions Temporal as the default durable execution layer for the most important agent framework in the market, creating a distribution flywheel that competitors cannot easily replicate. Every developer building production agents on OpenAI's stack now encounters Temporal as the answer to the "my agent keeps failing mid-workflow" problem. Enterprise validation is already here. NVIDIA, ZoomInfo, and Gorgias run mission-critical agent workloads on Temporal, proving the platform scales beyond demos. The $300M Series D at a $5B valuation — led by a16z — provides a war chest to out-invest rivals on engineering and go-to-market while signaling conviction from the firm closest to the AI infrastructure thesis. The Durable AI Agents Bundle packages Temporal's core value proposition (retries, state persistence, human-in-the-loop) into a product purpose-built for the agent era. With Ruby SDK reaching GA and authentication features shipping, Temporal is checking the boxes that unlock the last holdouts in regulated enterprises. Durable execution is not a nice-to-have for agents; it is table stakes. Temporal owns the category.

Bear case

Temporal's $5 billion valuation prices in domination of a category that may not remain independent. Durable execution is real infrastructure, but the question is whether it stays a standalone layer or gets absorbed into the platforms developers already use. AWS Step Functions, Google Cloud Workflows, and Azure Durable Functions all compete on overlapping capabilities — and they come bundled with cloud spend. If any of the hyperscalers builds a credible agent-specific durable execution service, Temporal's addressable market shrinks overnight. The OpenAI partnership cuts both ways. If OpenAI decides durable execution belongs inside its platform rather than alongside it, Temporal becomes a stopgap, not a standard. OpenAI has shown willingness to absorb adjacent infrastructure when it strengthens developer lock-in. Complexity remains a headwind. Temporal's programming model demands developers learn concepts like activities, workflows, and deterministic execution — a steep curve that limits bottoms-up adoption outside sophisticated engineering orgs. Meanwhile, lighter-weight competitors like Inngest ship "durable functions" with far less conceptual overhead. The $752 million in total funding also raises the bar for exit: at $5 billion, acquirers are scarce and the IPO window is unforgiving for infrastructure companies without software-company margins.

Products

Temporal Cloud
A fully managed durable execution platform that offloads the operational burden of running the Temporal Service. Temporal Cloud handles scaling, maintenance, upgrades, and database management so engineering teams can focus on building reliable application logic. It encrypts all data in transit, keeps customer code and sensitive data isolated, and is trusted by top financial institutions for mission-critical payment flows. Temporal Cloud integrates with the open-source Temporal SDKs for a seamless hybrid development experience.
Temporal Open Source (Self-Hosted)
The core open-source durable execution engine that provides crash-proof workflow orchestration. It guarantees that application code resumes exactly where it left off after any failure — whether seconds, days, or years later — by automatically persisting execution state and event history. Developers write business logic as workflows and activities using idiomatic SDKs, while the Temporal Server handles retries, task queues, signals, timers, and state recovery. It is used by Netflix, Stripe, Snap, and Datadog to run critical production processes.
Temporal SDKs
Officially supported software development kits for TypeScript, Go, Java, Python, .NET, and Rust (plus community SDKs for other languages) that let developers write durable, fault-tolerant workflows in their language of choice. Each SDK provides a natural, idiomatic programming model with testing suites, and the ability to rebuild workflow state from history for replay-based recovery. They enable developers to express complex orchestration logic — retries, human-in-the-loop pauses, multi-step rollbacks — as plain code without needing a separate DSL or state machine.
Temporal AI Agent Framework
An emerging product surface purpose-built for orchestrating AI agent workflows with durable execution. It ensures agent pipelines — including LLM calls, tool invocations, and human-in-the-loop approval steps — are resilient to infrastructure failures, with automatic retries and full state persistence. This allows developers to build production-grade multi-agent systems that can survive partial failures, maintain conversation context across interruptions, and recover from API timeouts without losing progress.
