You work directly with me.

HOW IT WORKS

Our Process

On every project, you’ll work directly with Michael Kiernan, GeoMaus’s founder, from the first call through to delivery. No project coordinators, no handoffs, no relayed messages. When something changes onsite or a deadline shifts, you’re speaking to the person who can make the call that day.

1
The First Call - Straight to Michael
You'll spend 30 minutes on a call with me, not a salesperson. We'll talk through your building, your timeline, and what you actually need at the end. If your project isn't a fit for us, I'll tell you on that call and point you somewhere better.
2
Onsite - Built Around Your Operations
We plan every scan day around how your building runs. Out of hours for retail and hospitality, around shift changes for warehouses, security-cleared teams for sensitive sites. You'll know exactly who's onsite, when, and what they're doing.
3
Processing & Verification
Once we leave site, your data is processed by one team and quality-checked by another. By the time anything reaches you, two people have signed off on it. You don't have to be the quality control.
4
Delivery - Exactly How You Ordered It
You'll receive your drawings and models in whatever format your design team, facilities manager, or asset manager already works in. Revit, AutoCAD, PDF & Matterport. Plus a project handover call so nothing gets lost in translation.
