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.
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.
Three tools. One team.
Each product solves a concrete problem we've seen across hundreds of European companies.
A no-code e-commerce platform with built-in AI and first-party analytics.
A GDPR alternative to Calendly and Cal.com — EU-hosted, brandable, with a built-in pipeline for teams.
Manage and distribute your product data to dozens of marketing and sales channels from one place.
