Golem
golem.cloud provides a durable agent runtime that automatically persists state, executes tool calls exactly once, and enforces policies through WASM-based sandboxing. The platform enables developers to build AI agents that can suspend for days at zero compute cost, resuming with full memory and call stack intact. Its transactional execution model ensures code runs exactly once through any interruption, preventing duplicate side effects like double-charges.

Problem
AI agents in production face reliability challenges including state loss during interruptions, duplicate tool executions, and security vulnerabilities from prompt injection. Developers must build complex infrastructure for persistence, exactly-once execution, and policy enforcement, which is error-prone and time-consuming.
Solution
golem.cloud provides a durable agent runtime that automatically persists state and effects without serialization or annotations, allowing agents to suspend for days or weeks at zero compute and memory cost. The platform executes code transactionally, ensuring tool calls complete exactly once even through crashes or restarts, while each agent runs in its own WASM sandbox with isolated filesystem, database, and environment variables. Policy enforcement is built-in through explicit grants for tools, network, and file access, with runtime-enforced quotas and journaling of all grants. Developers can write agents that pause for human-in-the-loop approvals via webhooks, resuming seamlessly when approval is granted.
Target Audience
Primary customers are software developers and engineering teams building production-grade AI agents and autonomous systems that require reliable state management, exactly-once execution, and strict policy enforcement.
