Sakana Aquarium

Sakana Aquarium is an ontology-based platform for building, running and operating enterprise AI agents, announced by Tokyo's Sakana AI on October 23, 2026, aimed at enterprise decision-making and execution.

Core components

• Ontology: models enterprise data, entities and relationships so agents understand business context
• Governance: permissions, auditing, compliance controls
• Managed Agents: agents hosted and run by the platform
• Workflows: defined in YAML, with human approval steps

Background
