Monsido was a multinational software company specializing in web governance solutions.
In January 2024, Monsido was acquired by Acquia. By October 2024, the Monsido brand was officially retired and rebranded as a Acquia Optimize. It now forms a part of Acquia’s Digital Experience Platform (DXP).

How does this impact Monsido customers?
Post-acquisition, Monsido’s customers have been split between two organizations:
- Monsido’s U.S. local government customers are retained by CivicPlus, who continue to serve them as a reseller of the Monsido platform.
- The remainder of Monsido’s customers are now under Acquia’s management, under the new brand of Acquia Optimize.
The packages and commercial terms for Acquia have changed from Monsido, as have their geographic locations.
