Who built Clamp, and why

Emmanuel Forge, Founder

I started my career as a civil engineer on a $600 million construction project. When I left to build my own remodeling business, I ran straight into a new problem: the business only worked if I did.

I was busy. Customers were happy. I was cashing big checks. And I was never getting ahead.

Overhead was a number I guessed at. My own time was not in the estimate, because it does not feel like a cost when it is your own hands. I was marking up job costs with a number I had heard somewhere, and wondering why a full calendar produced an empty account.

I had to start charging as if my life depended on it, because it does. That meant building the overhead honestly, classifying every cost exactly once, and letting the markup fall out of my own numbers instead of somebody else's rule of thumb. The guides on this site are that math, worked in public on a job whose every line item is published.

Somewhere in between, I have cycled, hiked, and kayaked 10,000 miles across America.

Why Clamp exists

Knowing the math is only half of it. The other half is the paperwork that carries a job from the first phone call to the final invoice, and for a one-person business that paperwork is where the money quietly leaks out. Change orders that never got written down. Photos scattered across a camera roll. An estimate that took three evenings because it started from a blank page.

Clamp is the app I wanted while I was running jobs: leads, design agreements, estimates, proposals, change orders, and invoices in one place, on the phone that is already in your pocket.

How this site is written

Every article here is worked from published data rather than assembled from industry averages. The 5x8 bathroom estimate is itemized down to 51 lines with its data files open, and the pricing guides do their arithmetic on that same job so anyone can check the work.

Where a number is a planning assumption, it says so. Where a figure could not be sourced, it was cut rather than softened. Ranges published here are Clamp planning defaults, not industry benchmarks, and the standing instruction to any contractor reading them is the one I had to learn myself: use your own numbers.

Articles are researched and drafted for Clamp and reviewed by me before publication. When a figure changes, the change is recorded on the article.
