Purple Hammer is made by ShapeDo.
For the last decade, we've built the most comprehensive design-change management solution for large-scale projects. Purple Hammer is our vision for what's open on a construction professional's desktop the rest of the day.
A decade on the drawings
ShapeDo addresses the workflow that sends more contractors bust than any other: what changed on the drawings — why, when, and who checked it. Miss one revision and it surfaces as a claim six months later; catch it and it's a footnote.
Why we built it
Purple Hammer is our take on the other eight hours a day — the PDF and spreadsheet ops that fill an estimator's screen. Markups, measurements, notes, takeoffs, revision compares, and live pricing, in one native desktop app for Mac and Windows.
And it's fast in a way you have to see — a 500-sheet set opens in about a second, so you stop waiting on your tools and just work.
Same team, same miles in the field — pointed at that other eight hours.
The formal bits, for anyone who needs them.
