One customer, a dozen disconnected identities
The same person logs in on mobile, clicks an email on desktop, calls support, and buys in-store and most systems treat them as four different people.
Device sprawl
Cookies, mobile IDs, and app sessions splinter a single person into anonymous fragments across every screen.
Channel silos
CRM, web, POS, and call-center systems each hold their own version of the customer with no shared key.
Stale stitching
Nightly batch matching means identities are always hours behind the customer's actual behaviour.
