Adrien Nussenbaum met Philippe Corrot in 2004. Two years later, in 2006, they founded Splitgames, a consumer marketplace.
In November 2008 the French retailer Fnac bought Splitgames. The pair stayed on and led Fnac's marketplace for about three years. They saw from the inside what a large retailer needs when it lets outside sellers onto its shelves.
They then created Mirakl, which offers marketplace technology to any retailer as a service. The company opened in Boston in 2015 and became a unicorn in 2020. It was also named to the Next40.
Mirakl raised $30 million in 2012, $70 million in 2019, $300 million in 2020 and $555 million in 2021. Its valuation was above $3.5 billion in September 2021.
