The problem

A D2C brand answered every order-status question by hand, lost abandoned carts silently, checked stock in a spreadsheet each morning and spent a full day building ad reports.

What we built

  • An AI support agent for web chat and email, with memory, a knowledge base and tools to look up orders, products and returns
  • Abandoned-cart recovery: AI-written emails at 1 hour and 24 hours, stopped the moment the order is placed
  • Order-status pushes, review requests after delivery and win-back for lapsed customers
  • Low-stock alerts with reorder triggers, catalogue sync and AI product descriptions
  • A daily founder brief, weekly feedback themes and knowledge-gap reports
  • A Meta Ads layer that surfaces winning creatives and pauses ads breaking ROAS / CPA rules

How it flows

From trigger to done, step by step.
