Software studio · EU

We build tools that companies actually use every day.

Brutuscore Group is the home of Merzio, Callio and Datara — independent SaaS tools for e-commerce, scheduling and product data. Built in the EU, with a focus on speed, GDPR and data ownership.

How we work

Real tools for real businesses

We don't sell services. We build products we use ourselves, and we open them up to the world.

Built in the EU

Hosted in the European Union, fully GDPR-compliant, and zero dark patterns in our privacy controls.

You own your data

Our tools collect first-party data straight into your infrastructure. No middlemen, no export caps.

No developer required

Every tool is designed so marketers, operators and founders can set it up themselves — no waiting on engineering.

One price, every feature

No enterprise tiers. You pay for scale, not to unlock the basics.

Our products

Three tools. One team.

Each product solves a concrete problem we've seen across hundreds of European companies.
