How they work

Constellation Software is a Canadian listed company that buys and operates software businesses serving specific industries. Its nine operating groups handle acquisitions and support more than 1,100 businesses worldwide. Acquired companies retain local leadership and are held for the long term.

Constellation directs acquisition enquiries to its operating groups or central contact team. Each group handles new acquisitions. Its model is to retain acquired businesses indefinitely, preserve their culture and local leadership, and support growth through shared resources and disciplined capital allocation.
