Vacabee — the AI concierge that doesn't just search. It books.

Mr. Bee plans trips in natural conversation and books them on the spot: flights, hotels, dining — by voice or chat. CPI Technologies built the platform end to end, from the AI core and booking infrastructure to the native iOS and Android apps.

The challenge

AI assistants deliver lists — the booking happens elsewhere.

Most AI assistants answer travel questions with lists of options. Comparing, configuring, and booking is still on the user — on other websites, in other apps. Vacabee set out to close exactly that gap: a concierge that doesn't just recommend a trip but completes the transaction.

In technical terms, that meant a real-time speech-to-speech pipeline, integrations with global travel inventory like Amadeus and RateHawk, payment processing including cryptocurrency via Coinbase — all inside a mobile app that clears Apple's and Google's review processes.

Our approach

One platform, three layers.

CPI architected Vacabee from the ground up: an integration layer for inventory and payments, an AI core for language understanding and preferences, and an action layer that verifies availability and completes bookings.

From conversation to confirmed booking

The voice-first interface runs on a custom speech-to-speech pipeline. Mr. Bee understands context, remembers details like seat preferences and budget, suggests fitting boutique hotels, and presents booking cards with real-time pricing — confirmed in the same conversation, no forms involved.

Personalization from onboarding onwards

A multi-step onboarding captures travel style, flight and food preferences, and hotel standards. The result is a preference profile the AI core draws on with every request — recommendations get sharper with each booking. The app takes voice and chat input interchangeably.

Scope of delivery

What CPI built

Every building block came from one team — from the AI core to the apps in both stores.

Voice-first concierge (Mr. Bee)

Speech-to-speech AI with contextual understanding — talk or type, book mid-conversation.

Native iOS & Android apps

Both apps approved by Apple and Google, plus the web platform.

Travel inventory integrations

Amadeus and RateHawk supply flights and hotels with real-time pricing.

Payments: fiat & crypto

Payment processing via PayPal and Coinbase — cryptocurrency included.

Preference engine

Contextual memory across conversations: seats, budget, travel style.

Booking dashboard

Upcoming trips, check-in, and boarding passes in one place — restaurant reservations included.

The results

Live in both stores, award-winning in Miami.

Vacabee secured approval from both Apple and Google Play, putting it within reach of over 5 billion devices worldwide. The platform launched with trips to New York, Miami, and Los Angeles.

The company won the Evergreen Award for Best AI Start-Up in Miami 2025 and picked up coverage from Business Insider, Benzinga, and The AI Journal, among others.

Where it stands today

From concierge to travel infrastructure.

Vacabee now positions itself as travel infrastructure for the AI age: Mr. Bee (mrbee.ai) bundles flights, hotels, transfers, eSIM, visa support, and invoicing into a single conversation — Amadeus-connected, with an operations team behind the AI.

The same booking engine runs as a white-label product for clinics, hotel groups, and companies — the first packaged vertical for medical tourism is live at Quantum Biohack — and is open to developers through a REST API.
