With Gobble I'll happily pay a weekly subscription and make dinner all the time. With Solve, most people only travel a few times a year.
Maybe this reinforces that Solve is more for (frequent) biz travelers, where it would be stickier.
I have a few friends who are management consultants who fly literally every week, their companies might pay $200 for them to save a few hours. It's probably easier to charge a fortune 500 a few hundred bucks per employee than it is individuals. Worth noting that it's US-only travel though.
It's kinda like when people started expensing Ubers from the airport rather than taxis.
