Hessian

Hessian is a Y Combinator (Spring 2026) startup building a forward-deployed AI agent platform for automating business operations. Its engineers embed on-site to map real workflows, then build and operate custom AI agents on the Hessian platform to run those processes end-to-end — spanning sales proposals, financial reconciliation, data management, and internal-system synchronization. The platform surfaces workflows, task and agent orchestration, workers, queue groups, prompts, assets, artifacts, secrets, webhooks, and audit logging, with integrations for tools such as GitHub, Slack, Postgres, AWS, Docker, Kubernetes, OpenAI, and Claude. Hessian does not yet publish a public API, developer documentation, SDKs, or an OpenAPI definition; this profile captures its verifiable public identity and web properties while the developer surface is awaiting release.

Hessian is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Automation, and Workflow Automation.
