The G2 Summer 2026 report is out, and the iMIS^® has earned Leader badges in the Professional Association Management, Nonprofit CRM, Fundraising, and Donor Management categories.

This is the 34^th consecutive season, and the 9^th year, since Spring 2018, that iMIS has defended its Leader title in the Association Management Software category on the Enterprise Report Grid®.
