FAQ

Questions, answered.

Klare Antworten auf die Fragen, die wir am häufigsten hören.

Who do you build for?

Companies with complex processes that need reliable, custom software — from startups scaling fast to established SMEs digitising operations. We work with clients across Europe and beyond.

Do you build custom software or products?

Both. We operate our own SaaS products (Mensura, Acturio, Innoflat, LinkTik) and build tailored software engineered precisely to your requirements.

Where is our data hosted?

On our own infrastructure in Europe. Everything is GDPR-compliant by default, with data residency you can rely on.

What technologies do you use?

Modern, proven stacks: Laravel, React, Next.js, TypeScript, Docker, PostgreSQL, and cloud infrastructure (AWS, Google Cloud) with API-first architectures.

Do you support projects after launch?

Yes. We handle maintenance, further development, and technical operation to keep your software stable and secure in daily use.
