CB Insights Venture Capital Funnel (2023)Key Lessons Learned
1. Building on hostile supplier relationships is fragile
Kiwi.com's value proposition directly conflicted with airline interests. Airlines don't want their flights combined with competitors' routes because it complicates operations and liability.
2. Customer liability in novel service models
When virtual interlining connections failed, customers were stranded with no airline responsibility. The guarantee costs ate into margins and created PR disasters.
3. Screen scraping isn't a sustainable moat
Building a business on scraping data from companies who don't want you to have it is a ticking legal and technical time bomb.
