The Challenges of Launching One App for as Many as Possible

At the beginning, you had to get train companies on board. Were they ever worried that if you can buy upgrades last minute in an auction, that fewer people would commit to buying them ahead of time? Overwhelmingly, we're shifting people towards a mentality of factually I'd rather travel in first class than standard. The revenue upside for train companies is incredible. Like the upgrades is now a significant portion of their P&L. Their profit and loss. And we're changing passenger behaviour to think, actually, do you know what, if I see a good deal in the first class ticket I'll buy it, I won't go in standard class. I still travel me.
