Why accept a 30% loss?
Every missing contact is a lost opportunity. Most tools stop far too early.
30% of contacts missing = 30% of revenue lost. The math is simple.
Beyond the waterfall.
Listar isn't just a sequential enrichment tool. It's a multi-layered intelligence engine.
30+ Data Sources
Premium data sources queried in an intelligent sequence for maximum coverage.
Proprietary Database
Our own enriched dataset fills the gaps no external provider covers.
Smart Arbitrage
Cross-referencing logic selects the most accurate data across every source.
Cross-Validation
Every result is verified against multiple sources before delivery.
The result
Maximum Achievable Enrichment
Not a simple database. Not a classic waterfall.
A fundamentally different architecture.
Databases
- Rely on a single internal dataset
- Coverage capped at ~40%
- No fallback when data is missing
Waterfall Tools
- Sequential calls with no intelligence
- No cross-validation between sources
- Accuracy often sacrificed for speed
Listar
- 30+ data sources + proprietary data merged
- Smart arbitrage for accuracy
- Cross-validation on every result
