Adrien Nussenbaum, cofounder and co-CEO of Mirakl, joins McKinsey executive editor Daniel Eisenberg on this episode. Mirakl, the leading SaaS platform provider in the rapidly growing enterprise marketplace sector, was started in France about a decade ago by Nussenbaum and cofounder and CEO Philippe Corrot, who had sold their previous start-up, a digital gaming marketplace, to French retailer Fnac. The company helps both B2C and B2B companies set up their own online marketplaces, where they can leverage third-party vendors to offer their customers a much wider range of relevant products or services. It now counts more than 300 of the world’s biggest and most well-known enterprises as customers, including Macy’s, Target, Carrefour, Toyota, Siemens, Airbus, and L’Oreal. With more than $100 million in annual recurring revenue and more than $4 billion in transactions conducted over its platforms last year, Mirakl has raised close to a $1 billion in funding over the last few years, putting the company’s valuation squarely in the unicorn category. As Nussenbaum explains, Mirakl views marketplaces and the emerging “marketplace economy” as a way for many brands to start to “regain control of distribution” at a time when a handful of platforms have come to dominate the ecommerce business over the past two decades.
