Airbnb

Airbnb is a global travel marketplace that lets hosts rent out homes, rooms, and experiences to guests in more than 220 countries and regions. Born in 2008 from three air mattresses on a San Francisco apartment floor, it turned spare space into a category-defining business, went public in 2020 at roughly a $100 billion valuation, and in 2025 expanded beyond stays into Services and a redesigned Experiences product - positioning itself as an everything app for travel.
