Research & Data

Why referrals outperform every other channel.

Benchmark data behind the nudgey model. All statistics are drawn from peer-reviewed research and industry surveys — sources cited below.

The referral gap

Most satisfied customers are willing to refer — they just aren't asked in a way that makes it easy to act.

Referred leads convert differently

A referred prospect arrives with built-in trust. That trust translates directly into conversion and retention.
