Rebookify
Rebookify is a Riga-based travel-automation platform that turns the price volatility of hotel inventory into recovered margin for travel agencies, TMCs, and OTAs. The system ingests a customer's refundable bookings, continuously rescans the same and equivalent room types across dozens of supplier APIs, detects when a cheaper identical alternative is available before the cancellation deadline, and either alerts the agent or auto-rebooks to capture the delta — all without disturbing the guest's reservation experience. In practice this is a meaningful margin lever: hotel rates move constantly, and even a few percent of recaptured spread across a large corporate travel book flows straight to agency bottom line. The product combines price tracking, room-equivalence matching, and workflow automation tuned to the actual operational realities of travel desks, and is a representative example of the practical B2B AI automation wave coming out of the Baltic startup scene.
