Temporal Technologies Raises $550M Series E at $12.55B Valuation Led by Lightspeed to Scale Durable Execution

Temporal Technologies raised $550 million in a Series E at a $12.55 billion valuation to expand adoption of its Durable Execution technology, which lets long-running applications resume after failures; the round was led by Lightspeed with co-leads Wellington Management, Goldman Sachs Alternatives’ Growth Equity and Tiger Global. CEO Samar Abbas — formerly CTO and a longtime distributed-systems engineer who swapped roles with co-founder Maxim Fateev in April 2024 — said the funding addresses growing demand for reliable infrastructure for complex software and AI.
