Buddy for ecommerce

Customer context should not stop at the checkout.

Customer context is scattered

Important activity lives across tools, inboxes, forms, orders, and chats instead of one useful customer record.

Repeat purchase is left to chance

A buyer completes an order, then the next message they receive may be a generic promotion weeks later.

Segments are too broad

Recent buyers, VIP customers, product-interest groups, and inactive customers should not all receive the same thing.
