Each week we round up travel startups that have recently received or announced funding. The total raised the last week of March was more than $14 million.

Earlier this week we noted that Travelaer, a technology startup building booking engines and conversational interfaces for airlines, has raised $4.73 million (4.3 million euros) in an investment round led by Entrepreneur Venture. Pléiade Venture and others also participated.

>>Founded in 2014, HundredRooms is a vacation rental metasearch platform based in Palma de Mallorca. It has closed a $4.27 million (4 million euro) round of financing, led by Seaya Ventures, with participation from Mediaset and previous investors. The company’s total equity financing is $11.76 million (11 million euros), to date.

The 60-employee company plans to use the funding to focus on apartments managed by private individuals and to expand to consolidate the international expansion into Germany, France, UK, Italy, and Mexico. The company will spend on TV advertisement to boost brand awareness.

The platform integrates listings from numerous websites, such Airbnb, Homeaway, Booking, HouseTrip, HomeAway, and 9 flats. It says it lists nearly 7 million home rentals.

Beatriz González, founding partner of Seaya Ventures, said: “The vacation rental space is the fastest growing category in the travel sector (35% year-over-year). We believe metasearch will lead this category in the future, as it has done in flights or hotels. Hundredrooms is the best-positioned company to become the leader, given its outstanding team and a very sophisticated technology that can match properties identifying substantial price differences.”
