About

Construction doesn't have a software problem.

It has a connected workflow problem. We started ClaimStack because the industry had accepted disconnected commercial systems for decades, and paid for it in delay, duplication and margin.

Why we exist

Humans were the integration layer. So we replaced the wiring.

We spent years watching commercial information move by hand, from a variation on site, to an email, to a register, to a forecast, to a claim, to an ERP. Every hop lost time and truth.

And watching talented people burn hours a week inputting data that already exists, doing things that don't need their experience or brains.

Software existed for each step. None of it talked. The project team held the whole picture in their heads, and the business found out the whole picture months later.

ClaimStack captures a commercial event the moment it happens and keeps every downstream workflow connected. The system remembers. People make decisions.

What we believe.

Capture once

Commercial truth is recorded at the source, one time. Zero duplication.

Report on reality

Not history. The number you see is the number as it stands today.

Proactive over reactive

Risk should surface while you can still act on it.

Automate

Automate the low-value tasks, freeing teams to deliver better outcomes.

Mitchell Baker, Founder of ClaimStack
“We didn't want just another tool. We wanted a system that was connected and greatly reduced the cognitive load on already stretched project teams. Construction is hard enough without fighting the tools that are meant to make your life easier. That came from over 12 years living that exact experience.”
