Holy cow, they're good storytellers and it is packed with useful detail.
As far as I can tell, they're only YC funded. They have steadily growing revenue (given the assumption that more people are booking lodging through their site)

We scaled a rate that took us all by surprise. Obviously, some things are less important than others and we had to prioritize. We're getting around to updating the peripheral pages soon.
