About
The man behind Concentra
My name is Gergely Szabó (Greg). I founded Concentra, s.r.o. as a one-specialist consultancy focused on contact center technology. Since then I've worked with telecoms operators, banks, insurance companies and public-sector clients across Europe and the United States.
I believe in telling clients the truth: if I can't do something, I'll say so. When I say I can, I will. No filler teams, no project managers between you and the work.
AI Enthusiast
I follow the AI space closely and incorporate AI tools into my daily work, including using Claude as a development and reasoning partner. I'm genuinely excited about what AI-assisted tooling means for contact center development and automation, and I bring that perspective into the work I do for clients.
