How we compare to SubgradeIQ.
SubgradeIQ is the only other product targeting HDD subsurface estimation. They resell USDA SSURGO data capped at ~48 inches. HDD bores go to 25 ft. The geology in the 4–25 ft window only exists in real well logs, and BoreCast is the only product classifying them.
| Feature | DrillerDB BoreCast | SubgradeIQ |
|---|---|---|
| Depth window | 0–25 ft | 0–48 in (4 ft) |
| Primary data source | Real driller-reported well logs (~1M records, 22 states) | USDA SSURGO surface soil polygons |
| Coverage strategy | State well datasets + WGNHS bedrock + Shangguan global fallback | SSURGO only (where SSURGO maps the location) |
| Bedrock depth | Yes — fused from wells + WGNHS + ML model, with cross-validation | Inferred from soil restriction layer (often null) |
| Honest unknown gaps | First-class — depth bands, intervals, and confidence labels | Not surfaced in the UI |
| Provenance + audit trail | Per-interval support count, distance, and source well IDs | Source polygon ID only |
| Validation methodology | Reproducible held-out leave-one-out harness, +36 pp over baseline | Not published |
| Corridor analysis (line draw) | Yes — sample-by-sample profile + KMZ + branded PDF | Point queries only |
| PDF + KMZ export | Yes — every export carries provenance + classifier version | PDF only |
Comparison reflects publicly available SubgradeIQ marketing as of April 2026. If they ship feature parity we'll update this table — accuracy matters more than spin.
