The Science of Scaling a Service Business — book cover

From the author of Beyond Breaking Even

The Science of Scaling a Service Business.

The Service Business Owner's Playbook for Real Growth.

You made it past the hardest part. Now comes the part that catches almost everyone by surprise. You add the truck — and you get poorer before you get richer. That's not a mistake. That's how growth works. Real growth isn't a ramp. It's a staircase — every step drops into a valley before it climbs.

By Justin Hubbard — Founder of Grizzly Junk Pros. 16,000+ customers, 6,000+ jobs/year.

You survived the hardest stretch — the one where the business was just a job you couldn't step away from. You fixed the margins, built the systems, got the team running without you hovering over every job. And now a new kind of problem is showing up: the one where doing everything right and still watching cash get tighter as you grow.

The Science of Scaling a Service Business is the map for that next stretch. Not a hype book about hitting seven figures. A staircase, with every valley marked — so you can see the dip coming before it scares you into stopping, or worse, into growing blind.

Real growth isn't a ramp. It's a staircase.

Who it's for

Owner-operators building on purpose.

The owner-operator in the trades — junk removal, HVAC, plumbing, landscaping, cleaning, painting, power-washing — who already has a real, profitable business and wants to build a bigger one on purpose. Not a get-big-fast book. A map of the staircase, with every valley marked.

This isn't a book of testimonials yet — it hasn't launched. What it is: the follow-up to Beyond Breaking Even, written for the operator who took that playbook, built a real business, and is now staring down the decision that either grows the business or breaks it.

Where Beyond Breaking Even covers the fundamentals — pricing, positioning, marketing, operations — The Science of Scaling picks up exactly where that book leaves off: the moment you decide to add the truck, the hire, the second crew. The instruments and systems that keep people, cash, and quality from breaking as you climb, stage by stage, toward a business that runs like a machine.

About the author

Justin Hubbard.

Justin Hubbard

Justin Hubbard built Grizzly Junk Pros from zero to over $2M in annual revenue while living in Stamford, Connecticut. He no longer operates the business day-to-day. Today Grizzly runs from two HQs — Stamford and West Haven — executed by a team of pros following systems Justin spent years building and refining.

He currently lives in Tampa, Florida, where he writes, teaches, and runs Adimize, helping other service business owners do the same.

The Science of Scaling picks up where Beyond Breaking Even left off — the growth Justin lived through after the business stopped just breaking even, and everything that broke on the way up.
