Uber was considered a startup:

"Uber: The history of the ride-hailing app, from start to IPO" https://www.businessinsider.com/ubers-history

"[Uber] quickly became the world's most valuable startup, "disrupted" personal transportation and food delivery, and became an emblem of the arrival of the gig economy" https://www.investopedia.com/articles/personal-finance/11101...

"Kalanick tried to recruit him to join the startup, but at the time Uber looked like a luxury town-car service, not a worldwide transportation juggernaut." - https://techcrunch.com/2017/02/07/the-inside-story-of-the-ri...

Ditto Airbnb:

"Reservation-booking app Resy just got a massive investment from Airbnb, one of the most valuable startups in the world" https://www.businessinsider.com/resy-airbnb-investment-2017-...

Airbnb is one "of the top Travel, Leisure and Tourism startups funded by Y Combinator" https://www.ycombinator.com/companies/industry/travel-leisur...
