# Cayu

> Long-horizon AI agents for enterprise operations. Agents complete jobs end-to-end across days and weeks. You only pay for outcomes.

Cayu Technologies, Inc. builds hybrid systems: deterministic software for known procedures, and agents for judgment, ambiguity, and exceptions.

## Topics

- Long-horizon agents: durable agents that wait, remember, and recover across days and weeks
- Production agent runtime: Cayu Runtime (open source), Cayu Cloud, Cayu Compound
- Agent vs copilot: different ownership models and ROI metrics
- AI cost economics: dollars per outcome, not dollars per million tokens
- Forward deployed engineers (FDE): scoping, building, and compounding agent deployments
- Enterprise finance and FP&A: when to use agents vs deterministic software
- Energy, supply chain, and logistics operational agents
