About GPStimate
Built for contractors who are done guessing.
GPStimate gives commercial roofing contractors fast, accurate estimates — without the spreadsheets, manual measuring, or legacy-software frustration. We replace guesswork with precision, and friction with speed.
Our story
From the roof to the cloud
GPStimate was founded by Kenn Furr, a "10x" roofing estimator with ten years of experience in commercial construction. After years of watching good contractors lose bids to inefficient processes and bad software, Kenn saw an opportunity to remove the friction from estimating entirely.
We aren't software developers building for an industry we don't understand — we build software the way contractors actually work. We understand the knowledge path of an estimate: gathering information, converting it into knowledge, and transferring that knowledge to others. Our goal is to make every one of those steps as easy and efficient as humanly possible.
Our philosophy
The power of human-in-the-loop
At GPStimate we're an AI-native company — but we believe technology alone isn't enough.
“AI doesn't replace human skills, it enhances them.”
We don't build AI because it's a buzzword; we only use AI that genuinely helps our users work faster. By pairing human-in-the-loop review with known measurements, we deliver AI takeoffs at 98% accuracy or better.
Why we exist
Automating the tedious, empowering the unique
Roofing estimates today are often stuck in the past, with hours lost to manual measurements that put bids — and margins — at risk. We focus on building AI features that minimize these tedious, repetitive tasks.
By automating the takeoff and data-gathering stages, we let estimators spend their time and energy on what's actually unique from project to project — the strategy, the relationships, and the complex problem-solving that AI can't replicate.
Our values
The principles behind every decision we make.
Build what actually works
We go deeper than surface problems. We study how construction really operates — where time is lost, where inconsistency creeps in, and where systems break — then we fix that.
Simplicity is hard — do it anyway
If it feels complicated, we haven't solved it. We do the hard work to make things simple, intuitive, and fast.
Earn trust through precision
Our users depend on accuracy. Every output, every model, every detail must be something they can stand behind.
Stay close to the work
We don't build from assumptions. We stay connected to the field, the workflows, and the people doing the job.
Truth over comfort
We face reality early — whether it's in the data, the product, or ourselves. Honest feedback beats polite delay.
