Russian online hotel booking agency Ostrovok has added to its investment coffers with a further $15 million in capital.
The latest injection was led by Vaizra Capital Russia and sees the co-founder of Chinese metasearch engine Qunar and an early investor in Ostrovok, Fritz Demopoulos, join the Moscow-based company's board of directors.
The Vaizra fund is supported by Vyacheslav Mirilashvili and Lev Leviev, co-founders of Vkontakte, Russia’s largest social network.
The $12 million comes 15 months after a massive $25 million financing in early-2013 led by General Catalyst Partners.
Big name backers Frontier Ventures, Accel Partners and Russian technology investor Yuri Milner also participated at the time, as well as former Expedia boss Erik Blachford who was also involved in Ostrovok's undisclosed funding round announced in January 2012.
Ostrovok CEO Serge Faguet says the company will look to expand its existing network of properties on the site as well as boost its product development pipeline.
The company claims to have 250,000 properties currently available on the system, taken from a combination of 20 international distributors and 8,000 direct hotel partnerships (recent additions include Marriott, Accor, Rezidor and Fairmont).
Mobile activity comes via both iPhone and Android services, as well as a recently launched iPad app, a suite which the company says have been installed by over 220,000 users.
