Operational Partners for Construction · Contractors · Engineering · AEC

The project moves. The margin shouldn’t leak.

Whetstone embeds senior operators inside contractors, engineering and AEC firms to control change orders, protect cash flow, and keep projects on schedule and budget — so thin margins survive contact with the field. Business-side only: we never touch engineering sign-off or site safety.

⛰  Business-side only. We fix controls, cash and back office — never engineering sign-off or site safety.
Where we create value

Where construction margin leaks on the job.

Thin margins die by a thousand cuts — overruns, missed change orders, trapped cash. We find the operational leaks and close them.

01

Project Controls & Schedule

Keep projects on time and budget; kill overruns before they compound.

02

Change Orders & Billing

Capture every change and bill it — stop revenue leaking on the job.

03

Cash Flow & Retainage

Free trapped cash: retainage, WIP and slow pay-apps.

04

Procurement & Subcontractors

Tighten buyout, vendor spend and sub coordination.

05

Systems & Data

Make Procore, Sage and your stack give one reliable version of the job.

How we engage

Senior, discreet, field-aware.

We work alongside your PMs, finance and operations leaders — never inside engineering sign-off or site safety — diagnose fast, fix in the flow of the job, and hand back a business that runs clean.

01

Diagnose

Weeks, not months. We find where schedule, change orders and cash are leaking.

02

Fix in the flow

Change made inside the operation with your teams — minimal disruption to the job.

03

Hand back clean

Durable improvement your team owns, with the plumbing running quietly underneath.
