OccupationCEO of Viadeo

Dan Serfaty [1] (born February 5, 1966 in Strasbourg, France) is a French entrepreneur and businessman.

He is best known as the co-founder and CEO of the professional social network Viadeo.


After graduating from HEC Paris (Hautes études commerciales, Paris, France) in 1987, Dan Serfaty spent 2 years abroad before starting his entrepreneurial life. In 1989, he acquired a company in the tourism sector, which he turned profitable before selling it in 1991.

At the same time, he co-founded a company specializing in the distribution of imported clothing products from Asia, which he sold 10 years later.[2]

In 2000, he founded Aggregator,[3] a club dedicated to entrepreneurs, helping them share their experiences, ideas, and contacts with other club members. Uniquely, most of Aggregator's members were the CEOs of small companies, financed by venture capital, bringing them liquidity and private equity returns.

The Aggregator experience was the context where Dan developed the idea for a business-oriented social network, while working originally on some software that would allow club members to access each other's contacts.[4]

In 2004, with Thierry Lunati, he co-founded Viaduc–the original name of Viadeo–investing part of the first 5 million euros raised for Aggregator. In 2006, Viaduc became Viadeo,[5] as the company was aiming toward worldwide development, including launching its English and Italian versions. With over 60 million users worldwide, Viadeo is the second largest professional social network.[6]
