This resonates more with me:
"Airbnb makes its money in real estate. But everything inside of how Airbnb runs has much more in common with Facebook or Google or Microsoft or Oracle than with any real estate company. What makes Airbnb function is its software engine, which matches customers to properties, sets prices, flags potential problems. It’s a tech company—a company where, if the developers all quit tomorrow, you’d have to shut the company down. To us, that’s a good thing."
