Built by people who filled in the daily log on paper.

Why we built it

Dana spent eleven years as a project engineer and PM. Ruben ran jobs as a superintendent. Between them they had used five construction platforms, and watched most of them die in the field because the people on site never opened the app.

So they started with the field. A daily log that works with no signal, that copies yesterday's crew, and that a super can finish in the truck. Then RFIs and drawings, because that is what the daily log kept pointing at.

Job costing came later, built with two project accountants who wanted the PM and the books to stop disagreeing. Bids came last. Every module still has to pass the same test: would the super use it?

• RULE 01

  Field first

  If a superintendent cannot do it with one thumb on a cold morning, the feature is not finished.

• RULE 02

  Every login free but yours

  Unlimited users on every plan. A tool the subs cannot open is a tool nobody uses.

• RULE 03

  Your data leaves when you do

  Export everything, any time, in plain files. Nobody should stay with software because leaving is hard.

• RULE 04

  Say what it does not do

  Every product page lists its limits. We would rather lose a deal on the demo than in month three.
