How StageProof works

StageProof is a performance analytics platform for home stagers. We connect staging work to public transaction outcomes so stagers can build a verified performance profile backed by real market data.

Where the data comes from

StageProof combines two sources of information to build each stager’s profile:

From the stager: property addresses, stage dates, offer dates, and staging costs. These are provided when a stager adds a property to their portfolio.

From public records: sale prices, listing prices, close dates, days on market, property characteristics, and listing agent details. These are matched automatically using the ATTOM and RentCast data APIs. Agent network metrics are derived entirely from listing agent records on each property’s public transaction, not from stager input.

A property is marked as “verified” when it has been successfully matched to a public transaction record with complete sale data. Properties that cannot be matched remain in the stager’s portfolio but do not contribute to verified performance metrics.

What the metrics measure

Every metric on a StageProof profile is computed from verified transaction data. Over-ask percentage compares the sale price to the original listing price. Days to offer measures the time between staging completion and first offer. Value created is the dollar amount a property sold above its listing price.

Metrics that require a minimum sample size are suppressed until enough data is available. This prevents misleading statistics from small portfolios.

How market comparisons work

We compare a stager’s properties to all comparable transactions in the same area and price range. This provides context for how staged properties performed relative to the broader market. Comparisons are based on zip code and property characteristics.

As more stagers join the platform, StageProof will also surface aggregated insights across the broader listing market, helping agents understand staging impact at a market level, not just an individual stager level.

Data sources

StageProof uses three external data providers:

• ATTOM -- Public transaction records including sale prices, listing prices, listing agent details, and property characteristics.
• RentCast -- Market data and property valuations for additional context and enrichment.
• Google Geocoding -- Address normalization and geographic coordinates for mapping.

What StageProof does not claim

Correlation, not causation. StageProof measures what happened after a property was staged. We do not claim that staging caused any specific outcome. Market conditions, pricing strategy, property condition, and many other factors influence sale results.
