We don't just build products. We run one.

AreaSum is the flooring estimating tool we built for Project Floors, turned into a product. We design it, build it, run it, and answer for it. That is why we build for clients like owners, not vendors.

Where it came from

The takeoff tool we built for Project Floors & Design solved a problem every flooring estimator has: measuring from a floor plan by hand. A tool that good was worth more as a product than as a one-off. So we made it one, and Project Floors still runs on it every day.

What it does

AreaSum helps flooring estimators do their numbers fast and get them right. Calculators for the common jobs, and a carpet cut optimiser that works out the most efficient way to cut a room from a roll.

It runs on the same stack we use for client work: Next.js, Supabase and Stripe, deployed on Vercel.

Why it matters if you hire us

Most agencies never have to live with what they ship. We do. AreaSum is backed by 3,800 automated tests, which is how a small team ships changes quickly without breaking the thing people rely on.

That is the standard every client build gets. If it is going to carry real work, it gets built properly.

Let's see what your systems could do.

Start with an Operations Audit: we spend time in the business, then hand back a plain report on what to fix first and what it is worth. If the numbers do not stack up, we will tell you.

Ready when you are.
