Telepath Pro

Most B2B sales teams are flying blind. 69% of reps missed quota last year, and nearly half of all rep time is spent on deals that were never going to close. The problem isn't effort -it's targeting. Telepath Pro solves this by analysing your closed-won CRM data to reveal your real Ideal Customer Profile, then scoring every open deal against that pattern in real time. The T-Score measures firmographic fit (how closely a deal matches your winning profile), the W-Score measures behavioural alignment (is the deal moving like your past wins at this stage?), and the combined Confidence score tells you where to focus. Features include ICP Drift Intelligence, Rep Intelligence coaching, Deal Intelligence deep dives, Win Pattern analysis, and similar-deal matching. Connects to your CRM in 30 seconds. First insights in 3 minutes.
