Airbnb has raised around $2.95 billion across multiple large financings, including a $1.5B Series E tranche in Dec 2015, a $1B Series E round in April 2020 led by Silver Lake and partners, plus conventional debt and strategic liquidity measures during market stress in 2020. Founded in 2008, Airbnb scaled an online marketplace for short-term rentals and experiences. Funding helped the company expand global supply, improve trust and safety systems, build Experiences, and strengthen balance-sheet resilience through the COVID downturn and into broader hospitality innovation.
