Vacabee

Existing AI assistants provide information but fail to take action. Users receive lists of options but still have to navigate multiple websites, compare prices, and complete bookings manually. Vacabee set out to bridge the gap between AI search and actual transactions — creating a concierge that books, not just browses.

The technical challenge was immense: building a real-time speech-to-speech AI pipeline, integrating with global travel inventory providers like Amadeus and RateHawk, implementing secure payment processing including cryptocurrency via Coinbase, and delivering all of this through a mobile-first experience approved by both Apple and Google.

We architected and built the entire platform from the ground up — a three-layer system comprising API integrations (inventory, payments, airline partnerships), the AI "Brain" (preference memory, contextual awareness, backup plan logic), and the Action Layer (availability verification, option selection, secure payment, booking confirmation).

The voice-first interface was built on a custom speech-to-speech pipeline, enabling natural conversation where Mr. Bee understands context, remembers preferences like seat selections and budget parameters, and proactively suggests alternatives. The mobile apps for iOS and Android feature both voice and chat input, personalized onboarding with travel style profiling, and real-time booking management with check-in and boarding pass delivery.

Vacabee secured dual App Store approval (Apple & Google Play), gaining access to over 5 billion devices worldwide. The platform launched with an invitation-only MVP2, attracting early adopters, industry advisors, and brand ambassadors including Ana Maria Marković and travel influencers with combined audiences in the millions.

The company earned the Evergreen Award for Best AI Start-Up in Miami and secured media coverage in Business Insider, Benzinga, The AI Journal, and GlobeNewswire. Vacabee obtained Seller of Travel licenses and direct inventory partnerships, positioning the platform to bypass traditional OTAs entirely. The first 1,000 waitlist users receive lifetime savings on the subscription-based service.
