Mads Andreassen spent the majority of his investment career at Sector Asset Management’s healthcare-focused Gamma arm, which managed one of Norway’s longest-running hedge funds, the market-neutral Sector Healthcare Fund. He dedicated 14 years to Sector, starting as an analyst for the first three years until 2007, and then serving as an investment manager for the following 11 years. The fund was closed in 2024 after nearly 19 years of operation, several years after Andreassen co-founded Seior Capital Partners to manage a separate low-net long/short equity fund specializing in the healthcare sector. Additionally, he spent three years as an investment manager at Fondsfinans Kapitalforvaltning, joining after leaving Sector Asset Management in 2018, before co-founding Seior Capital.

Sissener AS, founded by Jan Petter Sissener in Oslo, manages the long/short equity hedge fund Sissener Canopus, in addition to investing in Nordic high-yield bonds. Utilizing a discretionary long/short equity strategy focused on bottom-up stock picking, Sissener Canopus has achieved an annualized return of 10.3 percent since its inception in May 2012.
