What Kaelio does
Kaelio is the company behind ktx, the open-source context layer that makes data agents reliable. Data agents today fail because they lack structured context and determinism. Metrics are defined in five places, governed in none. Teams spend months on semantic layer projects that never finish. ktx fixes that. Connect your warehouse, BI tools, and docs. ktx builds the context layer automatically. Your team governs it. Any agent can query it. One context layer across your entire data stack.

Kaelio
The open-source context layer for data agents
We are building ktx, an open-source context layer that connects data warehouses, BI tools, and documentation to create a single source of truth for metrics. ktx automates building this context layer so data agents using it have reliable, structured inputs, resolving the problem where definitions are scattered and governance is missing.
We do not have a fixed physical location. After YC, the company will remain distributed.
Our founding team is remote and works across locations which lets us recruit talent globally and stay flexible. We believe the best outcomes come from focusing on product and users, not geography.
