The Underwriting Problem

Traditional underwriting is slow, error-prone, and produces analysis you can't trust.

8+ Hours Per Deal

Research shows analysts spend up to 8 hours per deal on data collection alone, before real analysis even begins.

94% Have Errors

Academic studies show 94% of business spreadsheets contain at least one error. In CRE, those errors have cost billions.

Black Box AI

Generic AI tools generate plausible-sounding numbers. But can you verify where they came from?

The Groundstone Difference

We don't generate numbers. We extract them precisely and cite our sources.

What We Do

  • Extract data precisely from source documents (like Excel reads cells)
  • Cite every number to its source page, cell, or paragraph
  • Cross-validate metrics across multiple documents
  • Flag inconsistencies and missing information

What We Don't Do

  • ✕Generate plausible-sounding numbers from training data
  • ✕Make up metrics when documents are missing
  • ✕Hide the source of our analysis
  • ✕Pretend gaps don't exist

Frequently Asked Questions

How does Groundstone AI underwriting work?

Groundstone extracts data precisely from your deal documents (rent rolls, proformas, operating statements), then runs a 5-pillar analysis covering financial, property, market, sponsor, and executive summary. Every number is cited back to its source.

How is this different from ChatGPT or other AI tools?

Generic AI tools generate plausible-sounding numbers from training data. Groundstone extracts actual values from your documents and cites every number to its source page, cell, or paragraph. We never fabricate data.

What document types can Groundstone analyze?

Groundstone processes PDFs, Excel spreadsheets, and Word documents including rent rolls, proformas, operating statements, offering memoranda, appraisals, and environmental reports.

How long does an analysis take?

A full 5-pillar analysis typically completes in 10-15 minutes, compared to 8+ hours of manual analyst work for data collection alone.
