One team for the whole stack.
We design, build, and run custom platforms, the integrations and data beneath them, and the AI agents that work inside them. Security and approvals come with every part you choose.
Our founders have built and run 80+ production automations and production agentic AI and RAG systems at large enterprises.
Platforms.
Web apps, internal tools, and enterprise platforms, built from the ground up and scaled as you grow.
Software for the work no product covers: the tool your team needs, built around how it actually works, then kept running as the work changes.
Clef, our hotel concierge, is a product we designed, built, and run ourselves.
See Clef- Access only through credentials your team can revoke at any time
- Runs inside your own cloud, if you prefer
- Every step recorded by Control Plane
Integration.
ERPs, APIs, cloud services, and databases connected, so every team works from the same records.
Integrations between the systems you already run, and the data pipelines underneath them, so a change made in one place shows up everywhere it should and mismatches are flagged.
Integrations with the systems a hotel runs on, such as property management, housekeeping and point of sale, are in progress.
What we solve- We work only in the systems you connect
- Every connection is confirmed during mapping, before any build starts
- If a system can't connect, you hear it up front
Agents.
AI agents and automation built into your software, carrying routine work and passing hard calls to a person.
Agents that answer from your approved rules and documents, check what arrives, track what is due, and hand anything unusual to the right person with the full context attached.
Clef reads guest texts, routes what needs staff, and holds what needs staff for a named person.
Watch the Clef replay- Routine work runs inside the limits you set
- Anything above them waits for a named person
- Answers cite their source, so staff can check them
Governance.
Control Plane is the layer under every Elyon build that records each step, keeps credentials revocable, and holds anything past your limits until a named person approves it.
Control Plane, which runs under every build. It logs each step, and anything past the line you draw waits for the named person to say yes.
Control Plane is in every build we ship: every action recorded, every approval routed to a named person.
Security and control- Credentials your team can revoke at any time
- Every step recorded for review
- Subprocessor list on request
How a build fits.
Your systems feed one core. Agents carry the routine work, and every change waits at the gate for a person before it is written back.
