Viadeo is a Web 2.0 professional social network with over 50 million members worldwide in 2013, and a membership base that was growing by more than one million per month in 2009. Members include business owners, entrepreneurs and managers from a diverse range of enterprises. The site is available in English, French, German, Italian, Portuguese, Spanish and Russian.
Company information 
From November 2006 to August 2007, Viadeo raised €5 million twice in funding from investors AGF Private Equity and Ventech. Later that year, Viadeo announced the acquisition of Tianji.com, a Chinese business social network.
Six months after purchasing Tianji, in July 2008 Viadeo acquired its Spanish competitor ICTnet. Launched in 1995, ICTnet had 300,000 members and is popular in South America.
In early 2009, Viadeo acquired the Indian professional social networks services, ApnaCircle. ApnaCircle, with 300,000 members at the time of the acquisition, was founded by Yogesh Bansal and later joined by Sabeer Bhatia, co-founder of Hotmail, as board member.
On 13 October 2009, Viadeo announced the acquisition of the Canadian contact management website, unyk.com. At the time, unyk had 16 million members around the world, and made Viadeo second only to LinkedIn in terms of total membership.
The company is headquartered in Paris, and employs a global staff of 400, with offices in London, Madrid, Barcelona, Milan, Beijing, New Delhi, Mexico City and Montreal. The company recently opened an office in San Francisco. In 2009, Viadeo had estimated annual turnover of $40 million  and is profitable since last quarter of 2009.
Viadeo service 
Viadeo is a business-oriented online social networking platform. Viadeo lets members maintain a list of business partners, allowing them to stay in touch, use or help each other to find a job, or create business opportunities. In January 2013, Viadeo announced the acquisition of the French startup Pealk, to offer innovative solutions targeting SMBs .
Development strategy 
Viadeo depends on 3 revenue streams: premium membership, advertising, and services to recruiters. Viadeo's strategy is based on a glocal approach, assuming that most professionals do business locally. With 4.5 million members, China is the most represented country. Since February 2010, Tianji is available in English allowing non-Chinese professionals to communicate and network in China. One report in 2009 gave Viadeo 1.8 million members in France, where it had a strong competitive effect on the alumni networks of the Grandes Écoles, France's top tier schools. The same study found a certain amount of linguistic barriers between the networks, with Viadeo being "too Franco-French" while Linkedin was too Anglo-Saxon. Viadeo is mainly focusing on Europe and emerging countries such as BRIC countries.
