Illustrative example
The problem

Job data breaks down between the field and finance.

  1. Field capture

    Changes, progress and quantities aren't reliably recorded on site.

  2. Siloed data

    What does get recorded is split across apps, inboxes and files.

  3. Field-to-office gap

    Finance chases PMs and turns field updates into numbers in Excel.

  4. Late margin slips

    Overruns and unbilled changes show up late.

  5. Forecast uncertainty

    Cost-to-complete varies by PM and arrives late, so forecasts take extra work.

Other tools patch the old stack. Cantro is built new.

AI-native from day one, so it doesn't need patches to work.

Where we start

A WIP that stays current.

01

Updated as the job moves

Built from the reports and systems you already use.

02

One shared version

The field, PMs and finance work from the same numbers.

03

A consistent model

Every job is set up the same way, so the numbers hold up month after month, and with your bank and surety.

04

Works with your spreadsheets

Take the data into Excel whenever your team needs it.

The WIP is where we start. Our goal is one system for the job that field and office teams share.

What GCs get

Better for every team on the job.

Field

More projects, less paperwork

Simpler information capture, so PMs and superintendents can run more jobs.

Office

Less manual work

Numbers stay current without the month-end chase.

Margin

Margin protected

Slips caught early, changes recovered. At a ~4% margin, every 0.1% of revenue kept is 2.5% more profit.

Growth

Room to grow

Forecasts your bank and surety can rely on support more bonding capacity.

Why "Cantro"

A cantilever reaches further from the same support.

That's where our name comes from.
Cantro takes the manual, repetitive work off your team, so they have room for the next project.

Founding team

Ying Ge

Founder, Cantro

I've spent 14 years helping businesses understand their numbers and grow, first as a banker, then building accounting software.

At J.P. Morgan, I spent my days in companies' financial statements: learning how each business worked, sizing up its risks, and helping it get the financing it needed to grow.

At Intuit, I helped the company grow by building and buying. That included acquiring TSheets, the timesheet app many field crews use, and expanding into e-commerce. I then moved to QuickBooks to work on the hardest part of accounting software: the core logic that keeps the books right. I launched multi-entity accounting for Intuit Enterprise Suite and built AI accounting agents. Along the way, construction companies told me how much time they lost to data spread across disconnected systems.

Cantro came from asking GC owners, CFOs, project managers and superintendents directly where things break down today. Now we're building the construction software of the future, with them.
