Reports to: Lead Product Manager
We build the post-booking servicing layer — fare rules, schedule changes, IRROPS, refunds, waivers, traveler comms — that today still runs on thousand-agent call centers at the world's largest airlines, OTAs, and TMCs. We're backed by Nauta Capital, Amadeus Ventures, and Draper (raised $5M and soon raising a Series A), with ~20 enterprise customers including Direct Travel, TravelPerk, Kiwi.Acai is co-founded by Riccardo Vittoria, who previously built and sold 30SecondsToFly to American Express Global Business Travel, and Pavel Pratyush (ex-ManoMano, eBay).
We're a small, integral team across New York, Barcelona, and Pune. We're hiring a Senior Product Manager to own AI Travel Agent end-to-end — Acai's core product that reasons over a PNR, applies airline and agency policy, and executes changes directly in the GDS (Amadeus, Sabre, Travelport). This is the right role for a senior PM who has worked inside travel technology, understands how airline distribution actually works,



and wants to apply that expertise to a product that's genuinely replacing how the industry operates. You'll report to the Lead Product Manager and work alongside engineering and customer success leadership.
Lead discovery, scoping, prioritization, and delivery across the full post-booking servicing stack — exchanges, refunds, cancellations, IRROPS, and traveler comms — with pre-booking on the near horizon.
