Once a candidate accepts, recruiters lose visibility. The weeks before start date are a black box — candidates go quiet or take counter-offers, and the first signal is often a no-show. The clues are already in the inbox, buried in threads no one has time to reread. JoinIntelli reads that conversation (read-only, Gmail/Outlook), flags reply-cadence drift, tone shifts, and counter-offer language, pairs it with direct candidate check-ins, and turns it into one score. No surprises on start day.
