Reuters reported on Feb. 17, 2026 that Temporal - an open-source "durable execution" engine plus a hosted cloud - raised $300M at a $5B valuation. The round was led by Andreessen Horowitz (a16z), with Lightspeed, Sapphire, and existing backer Sequoia joining. The company counts OpenAI, Snap, Netflix, and JPMorgan as customers.

Context check: The $5B price tag doubles the valuation from an Oct. 1, 2025 secondary round led by GIC (Singapore's sovereign wealth fund) that valued Temporal at $2.5B. See the GIC press release.
Why this matters: AI agents do more than chat. They run multi-step jobs that touch flaky APIs, face timeouts, and can fail partway through. Temporal's durable execution model preserves the workflow state so code can resume exactly where it stopped - no lost progress, no duplicate charges, no bespoke retry spaghetti.
Think of a payment flow or a travel-booking agent that fails mid-process. Temporal restarts from the last good step instead of making you rebuild complex recovery code.

What the principals say:
- "When software moves from generating answers to executing work, the tolerance of failure becomes tiny," CEO and co-founder Samar Abbas said, framing reliability as the core problem. StreetInsider
- Andreessen Horowitz lead partner Sarah Wang called Temporal "the execution layer" for gen-AI infrastructure - translation: the glue that keeps long-running agent tasks alive. StreetInsider
What Temporal actually sells:
- An open-source engine (free) plus Temporal Cloud, a hosted multi-tenant service that runs the engine for many customers.
- Usage-based pricing: they operate the reliability layer for you and bill by what you run.
Founders' cheat sheet:
- Reliability is a gating factor, not a "nice to have," for agentic apps that touch money, operations, or humans.
- Skip the rebuild: durable execution can save weeks of senior site-reliability engineering (SRE) time you'd spend writing ad-hoc recovery code.
- Product vs. infra: if your workflows run for minutes to months - payments, order orchestration, multi-step agents - an execution layer de-risks launches.
- Signal check: big-ticket infrastructure still gets funded; this isn't just front-end AI hype. StreetInsider
Nerd notes, no buzzwords:
- "Durable execution" means checkpointing every step and deterministically replaying after crashes.
- "Multi-tenant managed service" means a hosted platform serving many customers with isolation and service-level agreements (SLAs).
- SRE stands for site-reliability engineering - teams that keep services running reliably.
