Brandt Hagen was forced to cease club operation in the Basketball Bundesliga (BBL) immediately in December 2003.

Phoenix Hagen wants to promote young basketball talents to ensure high-performance sport for the long term.

The young talents team Phoenix Hagen Juniors plays in the north-west division of the first league for Germany's up-and-coming players (NBBL).

The club filed for insolvency in October 2016 due to financial difficulties and had its Bundesliga license revoked with immediate effect the following month.

On Tuesday 02/05/09 the responsible board of the BBL decided to send a delegation to the proposed location in Hagen to inspect the site before making a final decision on the licence.

[9] Phoenix Hagen is eligible to maintain the licence, if progress requirements for the setup of the basketball arena will be fulfilled.

[11] Phoenix Hagen will have to present the arena converted and ready for match operation by 31 July 2009, which forms the final hurdle towards the 2009–10 BBL licence.

For the 2023-24 season, Hagen was especially well equipped for its frontcourt positions as they already had players Tim Uhlemann and Marvin Omuvwie, but were reinforced by Lennart Boner (came from Giants Düsseldorf) and Nazihar Bohannon (formerly Clemson Tigers), whereas Chris Harris continued to be the Head coach.

[12] The team reached the Final Four where they ceded to eventual league champion Karlsruhe Lions 1-3 victories.
