About

Golem Cloud

Golem makes durable agents the default. State survives crashes. Tools execute exactly once. Policies are runtime guarantees, not application code.

Our story

Golem began in March 2023, when John A. De Goes — mathematician, open-source advocate, and creator of ZIO — joined forces with longtime OSS contributors Daniel Vigovszky and Afsal Thaj. The first prototype was hacked together in Inverness, Scotland, proving that durable execution of WebAssembly components was possible — extending ZIO Flow's resilient-workflow ideas beyond the JVM.

The open-source Golem runtime followed shortly after, with development happening publicly on GitHub. Golem Cloud, Inc. was incorporated in 2024, and the managed Cloud service launched into Developer Preview the same year.

Today, the Golem runtime is open-source under BUSL-1.1. The Cloud service remains in Developer Preview; paid general availability with formal SLAs and data-retention guarantees is planned for Q3 2026.
