The investment keeps on coming into the vacation rental search engines - this time it's Holidu with a $6 million (Euro 5 million) Series A.
The Germany-based startup, which launched in 2014, has secured the capital injection from a list of investors led by EQT Ventures.
Others participating include Venture Stars and Senovo.
The company had previously raised Euro 1 million in a seed round.
Holidu claims to have more than three million rentals worldwide on its system, putting up against the likes of heavily backed Tripping in the US with its five million.
Chief operating officer Simon Meier says the round will be used to invest in the site's mobile capabilities and introduce new usability features.
Fellow German brand HomeToGo (now 3.9 million properties) has attracted funding of its own, having secured $8 million from early-stage investment house DN Capital and Acton Capital Partners, as well as other unnamed angel investors.
Holidu currently has a head-count of 20 (up to 30 within the next 12 months) and is available in German, English, French, Spanish and Dutch languages.
Vacation rental content is streamed in from a sizeable number of providers, including Booking.com (it's former boss Kees Koolen is a partner at EQT), 9Flats, TripAdvisor's FlipKey, HRS and TUI.
