Impact

1 in 3

leads is fake — the problem it removes

<100ms

TrustScore at submission time

5 min

from signup to scoring live leads

01

Challenge

Teams that pay for every lead lose up to a third of their budget to bots — an average 28% bot rate inflates cost-per-lead and burns sales time chasing contacts that never existed.

02

Strategy

Detect instead of punish: no CAPTCHAs or puzzles for legitimate users. Analyse behaviour invisibly — mouse movement, typing rhythm, timing — and make the system fail-open and GDPR-clean (no IPs, no PII).

03

Solution

One script tag (or a WordPress plugin) that generates a TrustScore in under 100ms at submission time: legitimate leads flow to the CRM, suspected bots get flagged. Free tier of 1,000 scores, usage-based pricing, no contracts.
