Jan Petter Sissener was born in Geneva in 1955. Following his parents' divorce, he moved to Norway and adopted his mother's last name, Sissener. After attempting law school in Geneva, he studied at the Norwegian School of Management. Following his graduation there he started working for E. Vestnes as a money broker.

In 1986 Sissener started working in Carnegie International in London, and in 1989 he moved back to Norway where he set up Carnegie's Norwegian branch. After turning Carnegie into one of Norway's greatest brokerages, he broke off in 1993 and established his own brokerage, Sirius Securities. Sirius became an immediate success and was acquired by Orkla Finans after only five months. Sissener lead Orkla Finans for the next seven years.

In 2001 he was again hired by Alfred Berg, this time as their Head of Nordic Equities. Alfred Berg became a great success under Sissener.

Kaupthing was, according to Starmine, amongst the best Nordic brokerages in 2008.

In 2009, Sissener AS was established as an alternative to other investment firms. The company has 2 active funds, Sissener Energy (2010) and Sissener Sirius (2009).
