Guillaume Rambourg, the former Gartmore star fund manager, has made the first of what is expected to be 20 hires for a new Paris-based hedge fund firm, Financial News can reveal.

The first appointment is Karim Moussalem, a managing director and head of cash trading at Goldman Sachs, who is leaving the US investment bank after almost a decade to join Rambourg in a senior investment role, according to several people familiar with the situation.
