I’m Pascal Gauthier and I’m pleased to be part of the Mosaic Ventures Team as a Venture Partner.

My day job is CEO of Challenger Deep, a bitcoin venture where we’re working on the next big digital revolution.

Before that I spent more than 15 years immersed in digital media and advertising technology. Early in my career, I led sales teams at price comparison service Kelkoo, both before and after its acquisition by Yahoo in 2004, ultimately becoming Commercial Director of Kelkoo sales for cars, travel and shopping.

I joined Criteo in 2008 where I spent 5 years, primarily as Chief Operating Officer and I was instrumental in the company’s rapid global expansion towards a $1 billion revenue business. Criteo is one of the most successful venture-backed companies in Europe and has a $2.5bn market cap on NASDAQ.

While serving as entrepreneur-in-residence at Index Ventures in 2014, I discovered the potential for bitcoin, and realised this transformational new technology could only prosper if all users had access to reliable security and useful information. That insight was the spark for Challenger Deep, which I founded with the goal to be bitcoin's ultimate data provider.

I also serve on the boards of two promising ad-tech companies and OpenX, and the secure bitcoin hardware wallet maker Ledger. I have also backed African remittance service BitPesa, as it combines bitcoin's potential as an asset, with the huge potential role for remittances in Africa.
