Gus Mejía, the construction project manager who makes Stamppa.
Gus Mejía Construction project manager

Hi, I’m Gus.

I’m a construction project manager, and I make Stamppa for the people who spend their week opening, checking and issuing drawing sets: architects, engineers, designers, document controllers and builders.

Why it is called Stamppa

Stamppa started with a problem of my own: stamping large drawing sets, hundreds of sheets at a time, and keeping a record of what was received, what was approved and when. That is where the name comes from.

While I was building it, I saw I could make my own PDF viewer, cut to the way we work with drawings: fast, stable, with layers, scales and revisions. Then came the whiteboard, and then the mind map, which now live together in one tool.

Today the viewer is the heart of Stamppa. Stamping is one of its tools.

This is how Stamppa introduces itself when you open it:

Hi. I’m a PDF viewer, and a fast one. Everything else here is a tool you can ignore until you need it.

How it got here

Stamppa grew inside Plano Base, on real projects, a few weeks at a time:

  1. A batch stamper for our own drawing control: “Received”, “Approved”, “For Construction” on hundreds of sheets at once, with the date and sheet number filled in, and a transmittal record.
  2. The PDF viewer becomes the heart of the app: tabs, markups, measuring to scale.
  3. The whiteboard and mind maps arrive. On Windows, Stamppa joins the right-click menu.
  4. One app for Windows and macOS, built from the same code.
  5. Printing and plotting rebuilt, autosave and crash recovery, live compare on the sheet, sheet sets, dark mode and the Spanish interface.
  6. A new whiteboard (Clean and Sketch looks, draw.io files, napkin mode), editing the style of the drawing’s own text, and menus organized by workflow.
  7. Faster on big sets, PDF/A for archiving, signing with your computer’s certificates, review round trips, set check and estimates from your takeoff.
  8. Stamppa 27, the first public release: three ways to edit text, Shift for straight lines in every tool, and Linear and Aligned dimensions.

What changes from here goes in the changelog.

The problems it is for

  • A heavy set that freezes the viewer. A CAD sheet full of layers and hatches, and every pan or zoom stalls. You should be reading the drawing, not waiting for it.
  • Revisions keep coming. Rev C replaces Rev B, and you need to see what changed, keep your markups and measurements, and know exactly what went out.
  • A set arrives and every sheet needs a stamp. Received, reviewed, approved, for construction, with the date and the sheet number, on a hundred sheets, one at a time. That is an afternoon gone.
  • Paying for years and keeping nothing. Most drawing tools are rented: however many years you paid, stop and you are back to a viewer. And most people pay for far more than the markup, measuring and printing they actually do.
  • Drawings that shouldn’t leave the office. Client drawings belong on your computer, not on someone else’s server.
  • Windows in the office, a Mac at home. Teams are mixed. The tool should be the same on both.

What I decided

Stamppa works on your computer, with no cloud; it connects only to confirm your license. The viewer comes first: open a heavy set quickly, read it, measure it, review it, compare it, print it. The tools (batch stamping, the whiteboard, the PDF toolbox) are there for the jobs around the drawings, so you don’t need a second program for the rest of the day. And after a year of paying, the version you have is yours to keep.
