Describe your project Compare all services
What's Included

A service built around your brief

  • Custom list building against criteria that don't map to a standard dataset
  • Data cleansing — deduplication, standardization, and dead-record removal
  • Append and enrichment: add firmographic, contact, or technographic fields to records you already hold
  • One-off projects or ongoing scheduled refreshes, depending on your need
  • A named point of contact for the life of the engagement
  • Delivery in CSV, Excel, or a direct feed into your CRM or marketing platform
Who It's For

Built for non-standard requirements

Teams with an unusual ICP, a legacy database that needs cleaning up, or a one-time project that doesn't justify a standing subscription use this service to get a scoped, fixed-deliverable engagement.
