Why this phone enrichment comparison matters
Prospecting is a precision game. And for precision, you need valid, up-to-date, and well-targeted phone numbers.

Equal budget: Max €40–€80/month
Metrics measured: success rate, real cost per number, value for money
🔬 Methodology:
- 100 LinkedIn profiles tested (first name, last name, LinkedIn URL)
- Hard profiles (large corps & public admins)
- Same budget for each tool (~€50/month)
- Metrics compared: success rate, real cost per phone number, overall value
