Kaelio

The open-source context layer for data agents

Y CombinatorSpring 2025ActiveB2BArtificial Intelligence

What they do

Problem

Data agents are unreliable because organizations lack a single governed, structured, deterministic source of context for metrics and data definitions across the stack.

Solution

Kaelio builds ktx, an open-source context layer that connects warehouses, BI tools, and docs to automatically create a governed context layer that any agent can query.

Who it's for

Data teams and developers at organizations using warehouses and BI tools who want reliable data agents and consistent metric definitions.
