High-end rental startup comes out of stealth to take on Airbnb

It's not a hotel room. It's not an Airbnb. It's a … Sonder?

A hospitality startup that you've probably never heard of has announced $85 million in new funding, bringing its total capital raised to $135 million. Sonder has been quietly operating a vacation rental network for the past four years, and it's officially coming out of stealth with the funding announcement. Greenoaks Capital led the latest round, with participation from Greylock, Spark Capital, Structure Capital and Harbourvest.
