iMIS
By Advanced Solutions International (ASI)
iMIS is a cloud-based Engagement Management System (EMS) developed by Advanced Solutions International (ASI). It is purpose-built for associations, nonprofits, unions, and other membership-based organizations. Unlike traditional Association Management Software (AMS), iMIS integrates CRM, CMS, fundraising, event management, and financial tools into a single platform, enabling organizations to streamline operations and enhance member engagement.
Advanced Solutions International (ASI) was founded in 1991, and iMIS has been its flagship product for over three decades. The platform has evolved from a basic membership management tool into a comprehensive EMS solution. Over the years, iMIS has consistently ranked as a leader in the association software space, earning top ratings from G2 and other review platforms. As of Winter 2025, iMIS has been recognized as the #1 Association Management Software for eight consecutive years, with high satisfaction and market presence scores across enterprise, mid-market, and small-business segments.
iMIS is a privately held product under ASI, and there is no public record of venture capital funding or valuation. ASI has grown organically through product innovation, strategic partnerships, and a strong global client base. Its financial model is based on annual subscriptions, implementation services, and partner-led consulting engagements.
