CompCurve is a B2B real estate and consumer data provider founded in 2017 by Eli Gratz, a licensed Illinois broker and active investor who built the company around a simple frustration: the data professionals need to prospect, underwrite, and market with is scattered, stale, and overpriced.

Since day one, we have collected property and consumer data directly from primary sources: county assessor and recorder files, MLS records, state licensing boards, public datasets, and proprietary channels. Every record is standardized, deduplicated, and verified before delivery, so what reaches you is accurate, decision-ready intelligence rather than raw exhaust.

The catalogue today spans nationwide property owner records covering 150M+ US properties with ownership, valuation, mortgage, and parcel detail; a 2.4M-record licensed real estate agent database refreshed monthly across all 50 states and Canada; consumer identity and behavior data powering skip tracing plus phone, email, and address append; and market signals including storm and hail events, building permits, and life event triggers that surface motivated sellers before they list. Data hygiene rounds it out: scrubbing, deduplication, and direct mail suppression lists that cut waste before a single stamp is printed.

Need something that is not on the shelf? Custom bulk datasets and APIs are the core of the business, from VIN and vehicle ownership data to homeowner intelligence audiences built to your exact spec. Delivery is flexible: bulk flat files, cloud transfer, or a fast REST API with RESO-aligned schemas. Pricing scales with you, from a fraction of a cent per API call to full-file enterprise licensing.

CompCurve works exclusively with businesses: brokerages, realtors, mortgage lenders, insurance carriers, investors, analysts, proptech builders, and marketing agencies. If it lives in public records or licensed consumer data, we can source it, clean it, and ship it in whatever shape your stack needs.
