About

Healthcare is drowning in follow-up work. We exist to carry it.

Reminders, enrollments, screenings, callbacks — the outreach and coordination behind good care outgrows any team's headcount. Gravity Rail builds AI Agents that take that work on progressively: humans stay in control, and AI earns each stream of work the way a good hire would.

What we believe

Principles you can verify in the product.

These aren't values-poster words. Each one shows up as something you can inspect on this site and test in a demo.

⛨Agents that know their limitsAn AI that can't say “this needs a person” has no place in care. Escalation is designed first, not bolted on — sensitive moments route to a human with the full conversation attached.
§Compliance baked in, not vendor-controlledGovernance, testing, and security controls are built into the platform — transparent, inspectable, and yours to configure. Compliance shouldn't be an afterthought, or your vendor's secret.
◐Humans first, AI as it earns trustEvery Workflow can start fully human-run in Operator Mode. Streams of work move to Agents one at a time — and move back just as easily.
◉Meet you where you areSome teams live in the app; some want the API, CLI, or SDK. Same platform underneath — you choose the surface, and you can change your mind.
The Company

The company, honestly.

Healthcare buyers reference-check the company before the product. Here's ours, without the gloss: Gravity Rail is a seed-stage, US-based company that builds one thing — a platform for healthcare AI Agents.

  • Seed-stage, deliberately small — the people who build the platform are the people who show up on your calls and answer your security questionnaire. There are no layers between you and the team.
  • Healthcare-first, not healthcare-also — the platform exists for regulated care settings: patient and member engagement across voice, SMS, email, and web, with human escalation built into every Workflow.
  • Based in the United States — where our healthcare customers, and the compliance obligations that come with them, live.

Built for regulated environments. Healthcare is where Gravity Rail operates today — and the same controls that make agentic AI safe here, like role-based access, approved actions, reviewable history, and workspace isolation, are what any regulated industry needs.

The full security story — governance, identity and access, testing, HIPAA safeguards, and progressive adoption — lives on the Trust page. Security documentation and BAAs are available via security@gravityrail.com.
