KLB Invest OÜ

We build and operate digital products.

KLB Invest OÜ develops and operates software products through KLB Studio, creating focused SaaS tools designed to solve specific real-world problems.

One company. One studio. Focused products.

A simple structure, by design: the company provides the foundation, the studio does the work, and each product stands on its own.
