Build a business that stands when the storms come.

You started your business for freedom. Somewhere along the way, it became a job you can't step away from.

Tanner Mullen has been there. At 22, he walked away from a banking career to save his family, and started a painting company with a Honda Accord and a prayer. Today that company runs without him, and the software he built serves more than 2,500 home service companies.

This book is everything he learned along the way: how to hire, sell, lead, and run the numbers, built on faith, integrity, and people before profit.

One brick at a time, you'll build a stronghold for your family, your team, and your customers.

31 days, one brick at a time.

Each brick is one chapter. Tap any day to see what it covers and the action you'll take.

How the 31 days work

  1. Read one chapter each morning

    Before you check your phone. Each one takes about ten minutes.

  2. Take that day's action

    Every chapter ends with one thing you can finish the same day, like posting a hiring ad or automating your lead response.

  3. Lay another brick tomorrow

    No skipping and no catching up later. In 31 days, the small wins add up to a different business.

Every chapter comes with a sketch

Sketch of four stair steps from implementation up to visionary
Day 4: The Four Levels of Value
Sketch of a lead arriving at 1 a.m. and getting a text, email, and call within three seconds
Day 13: The Three-Second Rule
Sketch of an owner turning down easy money to master one thing
Day 21: The Power of Saying No
