How we work

A replacement, not a patch on top of the old ERP.

Atrium is live and we're refining it with a founding firm before the open launch. Direct contact with the team building the product — no intermediaries.

I

Replacement of your current software

Not an add-on or a layer on top of CISI, Gesfincas, TAAF or Fynkus. It's the system that replaces what you already use, with assisted migration included.

II

LPH-compliant

Roles, visibility and audit trail designed under Spain's Ley 49/1960 (Horizontal Property Law). When a product rule conflicts with the law, the law wins.

III

No lock-in, exportable data

Monthly or annual with 15% off. No long-term contract. At any moment you can export all your data in open formats.

IV

Direct support and assisted migration

Initial online onboarding included (2 hours) and assisted migration from your current software. Email support, reply within 24 business hours.

Product status

Live since May 2026, refining with a founding firm.

We're honest about where the product stands: Atrium works and is being polished with a real firm before the open market launch. These are the guarantees we offer today.
