About us
Built from real COD experience — born to close more sales
Our journey started inside the Exoleads network in Argentina, when its founder reached out for support in building and scaling the project. With years of experience in the nutra and e-commerce industry, we helped shape the early foundation of Exoleads and later took charge of setting up and managing its call center operations.
As performance grew, our team of trained operators began closing more sales every day, proving the effectiveness of our structure and methods.
From that experience, we decided to create our own independent project — Linea K — a specialized COD call center designed to deliver the same level of quality and performance to other networks and advertisers.
Founded by two media buyers with deep expertise in nutra and COD, Linea K blends data, empathy, and precision to help your business scale faster and smarter.
