Founders LM Luca Martial Founder/CEO AA Andrey Avtomonov Founder/CTO About Kaelio 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.
