Viadeo is a French professional social network. It was founded in Paris in 2004 under the name Viaduc, and its members include business owners, entrepreneurs and managers; it is often compared with LinkedIn. It is delivered as a web service operated by the vendor and is not open source. The address viadeo.com now redirects to a Viadeo page on the Journal du Net website.
Viadeo was headquartered in Paris. In 2016, after a failed attempt at international expansion, the company was taken over by Le Figaro. The sign-up and login page now names CCM Benchmark Group as the recipient of users' data. Le Figaro is a French group, and no non-EU parent is indicated. Public sources do not describe where the platform's data is stored, so European organisations that use it for recruiting or networking should read its privacy notice for hosting and data-sharing details.
