Why we built Datum. I’ve spent my career helping home builders grow with technology. The same thing kept happening: builders sit on years of real cost data they can’t actually use, so they price from memory — and it quietly costs them margin on every job. Datum turns that data into one record you can trust. — Paul Wurth, Founder
Point Datum at the files you already have. It pulls every line item — no templates, no typing.
Messy lines become one clean cost record — per item, per unit, per supplier. Every number traces to its source.
See where every cost is heading, and catch drift from your history before it eats margin.
AI can finally read messy, non-standard construction paperwork reliably. Costs have whipsawed since 2021 and skilled labor is scarce — gut-feel pricing quietly bleeds margin on every job.
A senior person’s memory, a stale spreadsheet, last year’s numbers carried forward. Datum makes your own history the source of truth.
Demo data — click through the four screens.
Builders sit on years of cost data, buried in invoices, quotes, sub texts, and old bids. Datum reads it all into structured line items. Nobody else has built this.
Reading documents…
Pull up a job’s costs. Datum checks each line against your own history and flags anything off. Lot 14 — Maple Ridge, 2,640 sf custom.
Most builders work from memory and a spreadsheet that's months out of date.
| A spreadsheet & memory | Datum | |
|---|---|---|
| Where your costs live | Scattered across files, emails, and someone's head | One record, from files you already have |
| How current they are | Last year's numbers, updated when someone remembers | Updated from every new invoice, quote, and payroll |
| Traceability | A number with no source | Every number traced to its source |
| Catches a drifting cost | No | Flags any line that's drifted from history |
| Upkeep | Constant manual data entry | No data entry, no sheet to maintain |
