Built for the companies that build.

Aquifer builds apps for construction companies, accounting first, on one platform shared across every company on a project and connected to the systems they already use.

We spent years inside the systems construction runs on.

Aquifer was founded by a team that spent years building data infrastructure at scale. We came from Stitch (acquired by Talend, then Qlik), where we learned what it takes to move data reliably between systems.

We started in construction by connecting its systems: Procore, Sage, Viewpoint, ArcGIS and the rest. More than half a decade of building connectors into construction ERPs showed us what each one does with a day's work, which is mostly to wait for a person to key it in. The systems were designed in another era, and the work around them never left the paper age.

So we started building the apps we wished those companies had. Accounting leads: built this decade with AI as part of the product and built to run beside the ERP a company already has. It sits on one platform with Scheduling, Coordination, Canvas and Studio, shared across every company on a project. Why we built Aquifer Accounting tells its story.

Integrations and Exchange are products on their own: connections to 70+ systems, including the ones a company already runs, and the paperwork that moves between companies. Nothing has to be replaced to start.

The people behind Aquifer.

Aquifer was founded in 2021 by a small team out of Stitch, the data-pipeline company acquired by Talend (and later Qlik). Today we build for the companies that build.

Three things drive everything we build.

B.01

The work should happen once.

When the systems are connected, a record is entered once and lands everywhere it belongs. Nobody should spend the day keying a PDF into a screen or reconciling one spreadsheet to another.

B.02

Construction deserves software built this decade.

Most of the tech construction runs on was designed in another era, and the general tools that came after learned construction later, through add-ons. We build for the specifics: retainage, pay applications, lien waivers, the schedule, the field, and the companies that share a project.

B.03

Companies need to be connected, not just systems.

The hardest problems on a project aren't inside one company. They're between companies. Owners and contractors. Contractors and subs. Utilities and their contractors. We built Exchange because connecting companies matters as much as connecting systems.
