CompCurve vs PropStream: investor software or bulk data built to brief?
PropStream is a popular subscription tool for real estate investors and agents to search properties, pull lists and skip trace. Here is how it compares to buying data from a boutique.
Comparisons reflect publicly described product positioning as of September 2026. Vendors change offerings often; verify details with them before deciding.
| Dimension | PropStream | CompCurve |
|---|---|---|
| What it is | Self-serve web and mobile app with property and MLS search, list building, comps, skip tracing, AI scores and marketing | Data consultancy delivering bulk files, feeds and APIs built to your brief |
| Best for | Individual investors and small teams pulling lists inside a UI | Teams that need whole populations, custom joins, monthly refreshes or an API |
| Volume | Subscription with monthly export limits and per-record skip-trace fees | Any volume, priced per record or per license, with match rates reported before invoicing |
| Verification | Skip-trace results ranked by likelihood, with DNC and litigator flags; no published accuracy or match rate | Carrier line-type and activity verification, DNC and litigator scrubs, measured rates |
| Signals | 165+ filters: distress, mortgage and lien, probate, divorce, vacancy, MLS, demographics, AI propensity scores | Daily signal files: expireds, solds, new listings, vacancy, foreclosures, obituary-linked |
| Beyond property | Property-anchored, with consumer contacts, court and life-event records, and census demographics | People, auto, licenses and B2B professional data on the same keys |
| Ownership of output | Exports under platform terms | Files delivered to you under a data license |
Pick PropStream when you want to search and export lists yourself, tens of thousands a month, inside a familiar investor tool.
Pick CompCurve when you need tens of thousands to millions of records, daily signals, a verified-mobile file for a territory, or a population the tool cannot filter to.

Plenty of investors keep a PropStream seat and buy their bulk files and daily expireds from us. We are happy to be the second vendor.
Want both? That is common.
Many clients keep a platform subscription for lookups and use us for the bulk pulls, the append passes and the niches the platform will not stock.
