Piranha Bytes is a German developer founded on October 12, 1997 and located in Essen (Ruhrgebiet), Germany. Formerly it is the name of a now defunct company, the registered trademark and label "Piranha Bytes" was transferred during a management buyout. The company's legal name is now Pluto 13 GmbH. They are best known for their Gothic and Risen series.
On May 22, 2007, Piranha Bytes announced the separation from her former publisher JoWooD Entertainment. Due to a contract between the two companies, JoWooD retained some rights to the Gothic name and to current and future games released under this trademark. After JoWooD Entertainment went bankrupt in 2011, Piranha Bytes started a new distribution agreement with the company that acquired JoWooD - Nordic Games GmbH.
Until these events, the titles in the Gothic series were the only games Piranha Bytes had produced. No longer able to use the series they started a new one called Risen.

Piranha Bytes are developers of computer games located in the Ruhrgebiet, Germany’s industrial heartland. They have developed the much acclaimed GOTHIC® (publisher: Shoebox and JoWooD) and Risen® (publisher: Deep Silver) computer roleplaying series.
Pluto 13 GmbH was founded in 2002 by employees and management of Piranha Bytes Software GmbH. Piranha Bytes Software GmbH was itself founded in 1997 and later (1999) turned into a 100% subsidiary of Phenomedia AG, a company listed on Germany’s Neuer Markt stock exchange. In 2001 the first GOTHIC game was released to the public. In May 2002 Phenomedia AG went into insolvency proceedings due to irregularities for which several former group managers (not Piranha Bytes’ management!) have been tried for in a German criminal court of law.
It was therefore decided to make a clean cut and negotiate an MBO with the administrator, which was concluded in September 2002. Pluto 13 GmbH was founded and major assets, trademarks and most staff were transferred to the new company. One of the four original founders remains with the team in a leading position.
Pluto 13 GmbH is a privately owned limited liability corporation under German law, all shares are held by staff and management. Current (2013) permanent staff is around 20 people - all but of one doing active development (designers, programmers, scripters, artists...).
