Anthony C Johnson

I help Houston home service companies find the revenue already sitting in their customer data, then go after it.

Work with CTSG My background
What I’m building

CTSG: customer data and campaigns for home service companies.

I connect a company’s field software and QuickBooks into one database they own. Each month I find the revenue sitting in it, run the campaigns that go after it, and report what came back against a holdout group.

  1. Unsold estimates

    Quotes that went quiet, scored so the strongest get followed up first.

  2. Dormant customers

    Past their normal service interval and not calling. Win-backs go to the ones most likely to book.

  3. Maintenance plans

    Good repeat customers who are not on one yet.

  4. Measured, not guessed

    A random slice of every list gets nothing. The difference is what the campaign caused.
