Carfax: from 10,000 records faxed in 1986 to 35B+ records across 151,000+ sources — sold to S&P Global Mobility 2022

Claim: CARFAX was founded in Columbia, Missouri in 1984 by Ewin Barnett III and Robert Daniel Clark. Its first dealer-market vehicle history report (1986) was built on a database of exactly 10,000 records distributed via fax. Today: 35+ billion records from 151,000+ sources including motor-vehicle departments for all 50 US states and 10 Canadian provinces. Sold to S&P Global Mobility in 2022.

Confidence: Verified.

The canonical "operational byproduct becomes the product" story. CARFAX's dealer (B2B) business eventually surpassed its consumer (B2C) business — the database that started as a sales-aid for one industry became the asset.

The 1984 → 2022 arc is 38 years. Most service businesses won't live long enough to mature a database to product status — but the structural decisions that make it possible (canonical entity IDs, normalized schema, time-series accumulation, proper provenance) are the same architectural decisions that improve operational value at every stage along the way. The dataset moat is a side effect of doing the operational work properly.
