TripActions Co-founder Ilan Twig in conversation with Stephen Cummins: "Expenses are a pain in the butt. What you optimise for when you travel for work is completely different than what you optimise for when you travel for leisure. We thought if there is a way that we could then make people think about how they make their decisions when it comes to corporate travel more similar to how they do it when they book their leisure travel, there is an interesting opportunity for saving money for the company."
