Virtual interlining API connecting airlines and low-cost carriers
Tripstack operates a B2B flights-as-a-service platform that ingests 30B price points daily and processes 240M searches to power virtual interlining across non-partner airline networks. The hiring mix is heavily weighted toward product (8 roles) and leadership (4 directors), with engineering and sales understaffed relative to product — a pattern that typically signals either product-market fit requiring faster iteration, or friction between what's being built and what the market needs. Active projects focus on search/cache optimization and partner onboarding, while pain points cluster around scaling partner revenue and contract complexity, suggesting the core technical infrastructure is stable but go-to-market and partner operations remain bottlenecks.

Tripstack is a Toronto-based B2B flights-as-a-service provider owned by Etraveli Group since 2019. The platform enables airlines, OTAs, and distribution partners to create flexible itineraries by connecting low-cost and full-service carriers through an API, bypassing traditional interlining constraints. The company operates offices in Canada, India, and Poland, and processes over 240 million daily searches across a database of 30 billion price points. Revenue is driven through partnerships with airlines and online travel agencies; the business model combines API access fees with ancillary services including payments, fraud prevention, and customer support.
