Made for small businesses that run on the phone

Most office software is built for one industry and rents you your own data. CoreDemarc gives every kind of phone-driven office the same core: calls, calendar, customers, documents and billing in one place.

Why a server you own?

Your customer and patient data stays on hardware you control, not in a stranger’s cloud. The AI runs locally too. And with the server in your office, your team keeps working on the office network even if the internet goes down.

    Questions owners ask

    Who owns my data?

    You do. It lives on a server in your office (or one we host for you), and you can take a full copy any time.

    What happens if the internet goes down?

    With CoreDemarc on a server in your office, your team keeps working on the office network. Calls follow your phone provider’s backup rules, so callers still reach voicemail or the AI.

    Do you sign a BAA?

    Yes. For clinics and other HIPAA-regulated practices, Mesa Geeks signs a Business Associate Agreement.

    What does it cost?

    CoreDemarc is set up around how your business works, so pricing is custom. Book a demo and we’ll put together a plan for you.

    Do I have to change phone companies?

    Usually not. CoreDemarc connects to the numbers you already have.
