Builders already own years of pricing data. It's just trapped in invoices, sub texts, and old bids. Datum reads it and turns it into one number they can trust.

A cost source-of-truth for residential builders. No data entry, no master spreadsheet to maintain — Datum learns from the documents a builder already generates and keeps their real labor and material costs current.

STEP 01

Read

Point Datum at the invoices, supplier quotes, sub texts, payroll exports, and old estimates a builder already has. It extracts every line item — no templates, no manual entry.

STEP 02

Structure

Messy line items become a clean, deduplicated cost record — per item, per unit, per supplier — with provenance tracing every number back to its source document.

STEP 03

Predict & check

Track every cost over time, forecast where it's heading, and flag any live estimate that drifts from the builder's own history before it eats margin.

Why now

Models 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.

What it replaces

A senior estimator's memory, a stale master spreadsheet, and last year's numbers carried forward out of habit. Datum makes the builder's own history the source of truth.

Builders already sit on years of pricing — buried in invoices, supplier quotes, texts from subs, and old bid sheets. Datum reads what they have and turns it into structured line items. This is the part nobody else has built.

Reading documents…

Drop in a live estimate. Datum checks each line against the builder's own history and flags anything off. Lot 14 — Maple Ridge, 2,640 sf custom.
