MOZAIC Core
Built by people who ran the agency themselves
MOZAIC Core started inside a real estate agency, not a spreadsheet of feature ideas.
Our Story
MOZAIC Core was co-founded in May 2026 by Mike Koszo and István Pásku. PASKU.CO, István's own real estate agency on the Costa del Sol, is the platform's first and still-active reference client — every module shipped has run on a real agency's real leads before it reached anyone else.
What We Believe
One place, not ten tools
Leads, cases, clients and documents belong in one system, not scattered across WhatsApp, email and spreadsheets.
EU-native, not EU-compliant as an afterthought
Hosted and built in the EU from day one, not retrofitted for a compliance checklist.
Built for the firm, not just the owner
Every agent gets their own professional presence and client portal — not just a back-office dashboard for the boss.
