Airbnb's mantra that everyone should somehow "travel like a local" has seen it snap up Spanish activities provider Trip4Real.
Terms of the deal have not been disclosed.
Co-founder and CEO, Gloria Molins, who is currently on maternity leave, confirmed the acquisition via email and says further details about the deal will be shared in the coming months.
Trip4Real (TLabs here) first appeared on the scene in mid-2013 with a platform to connect travellers with locals who are willing to provide their own, personal tour or activity in a destination.
Products range from tours of a local market to a cycling expedition around a city.
The founders initially invested $40,000 in the business, with an additional $75,000 funding received from the Spanish government.
A further $1.35 million came in via Caixa Capital Risc and Kibo Ventures in June 2014 and then another €1.4 million from Emprendetur and Enisa in the summer of 2015.
Trip4Real already had a deal with Airbnb to push its local-run activities to guests of the accommodation giant's hosts.
An Airbnb official says:
"We are delighted to welcome Trip4Real to the Airbnb family. Gloria Molins and her team share our vision of a different kind of travel experience that is local and authentic.
"Their experience and expertise is a great complement to our ongoing efforts to transform the way that people travel."
