Coliseum was founded in 2010 by Michael Rennschmied. It started as a quarterly publication, but quickly developed to a conference format – first established in the Middle East. Only four years later, Coliseum Summits expanded globally into US and Europe, later also into China and Latin America.

Since 2019, Coliseum developed to a membership-based organization, Coliseum – Global Sports Venue Alliance, and it is a 24/7-365 community. Though it is primarily about stadiums and arenas, but also the international experts are united within the alliance, dedicated towards building the best global community of sports and entertainment venue executives and professionals creating better and more profit able venues.

Coliseum facilitates a dialogue between stadiums, arenas, clubs, leagues and experts and enables them to learn from each other while establishing relationships. Coliseum’s digital 365Coliseum Business Center is a vast pool of resources for the stadium and arena industry worldwide. The most popular feature is the ‘Get in touch’-Service, giving members the opportunity to connect with many stadiums and arenas around the world.

Only in its first year, Coliseum – Global Sports Venue Alliance – grew to over 200 members and is in a position to offer 61,000 industry contacts worldwide, nearly 2,000 in-house editorials, 150 videos, and a construction database with over 500 current projects.
