**ACME Travel** is an enterprise AI travel agent. You describe a trip in plain language; it checks company policy and traveler preferences, ranks flights and hotels, and books on a corporate test card. Everything sits in MongoDB Atlas: orgs, policies, bookings, expenses, and a cached inventory so searches stay fast between sessions. The hackathon angle is durable context. Profiles and preference signals live in MongoDB and affect the next recommendation. After a trip, SMS or web feedback updates that profile and can open a policy suggestion for a manager to edit and apply. Five demo orgs each keep their own rules, approvals, and suggestion history, so the agent improves from stored memory instead of starting over every chat.
