G2 Fall Report 2025: iMIS Leads Association & Nonprofit Management

The G2 Fall 2025 report is out, and the iMIS Engagement Management System (EMS) has earned Leader badges in the Association Management Software (AMS), Nonprofit CRM, and Fundraising categories.

This is the 31st consecutive season, since Spring 2018, that iMIS has defended its Leader title in the Association Management Software category on the Enterprise Report Grid®. The G2 software review site rates products and vendors based on feedback and ratings gathered from B2B software users like you, along with data aggregated from online sources and social networks.

Purposely built to help associations achieve great things, iMIS does so much more than an AMS. iMIS is the industry’s only Engagement Management System (EMS) platform. With increasing market presence and high customer satisfaction, nothing makes us prouder than our happy customers who brought us to be #1.

• 4 Leader badges in the Association Management category in the Association Management Grid® Report (Momentum Leader and🏆 the #1 Leader!), Mid-Market Association Management Grid® Report, and Small-Business Association Management Grid® Report.
