AI property data, skip tracing and direct mail for real estate investors
One search bar handles address lookups, owner lookups and plain-language list requests across 150M+ properties, 240M+ people and 50M+ company records.
Describe the campaign you want in natural language or upload a CSV, and the AI translates it into a precise property search with 800+ refinements such as equity, vacancy and ownership length.
Append verified phone numbers, emails and 100+ extra data fields to any property or contact list, then export to CSV or deliver it via API.
Tag distressed properties on the go, track routes for teams, capture photos and pull owner details instantly while still in the field.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
