I get the sentiment for YC, but “not one” is pretty impossible. Airbnb reported a profit in 2017 and 2018. https://www.bloomberg.com/news/articles/2019-01-15/airbnb-sa...

It did lose money in 2019, but because of preIPO marketing and advertising. Marketplaces have great network effects and profit margins, seems like a very viable self sustaining standalone company. https://www.fastcompany.com/90418766/report-not-even-airbnb-...
