Hospitality company Sonder has ambitions to become the next-generation Hilton or Marriott as part of its plan to radically redefine the industry. The San Francisco-headquartered firm has raised a total of $360 million in funding and has been putting the money to use growing in cities across the world. Speaking at Skift Short-Term Rental Summit, Sonder co-founder and CEO Francis Davidson said it was important to learn from the big hotel companies but then rework how to do things better and more efficiently.
