Los Angeles-based on-demand massage company Soothe has received US$35m (€31m, £24m) in growth financing from its previous investor, The Riverside Company, bringing its total funding to US$47m (€42m, £33m).

Soothe has launched in 22 US cities since it started operations in 2013, and has plans to launch in 20 more by the end of 2016. The company said the new funding will allow it to bring its same-day, at-home massage service to every major US market.

“We’re thrilled by the demand we’re seeing among clients and massage therapists alike who are eager to experience on-demand massage as a routine form of wellness,” said Soothe founder and CEO Merlin Kauffman. “Our growth is in large part due to the incredible experience Soothe’s massage therapists provide, and it’s only just beginning for us.”

Kauffman created the company while he was at Harvard Business School, a period when he was frequently traveling and found it difficult to schedule a massage appointment outside standard business hours. The company is growing quickly, doubling the number of massage therapists on the platform since last year, and operates in Los Angeles, San Francisco, New York, Atlanta, Austin, Boston, Chicago, Dallas, Fort Worth, Ft. Lauderdale, Houston, Indianpolis, Miami, Minneapolis, Philadelphia, Phoenix, San Diego, San Jose, Scottsdale, Seattle, Vancouver and Washington DC.

“While many companies have failed on the promise of ‘Uber for X,’ Soothe is a proven leader in a valuable market, and we’re eager to support them again as they look to expand,” said Riverside Company managing partner Loren Schlachet.

In September, Soothe acquired its competitor Unwind Me, expanding the firm's presence in the San Francisco market.
