IMM Convening 2027

Building on the success of the inaugural IMM Convening in Montreal earlier this year, the Impact Principles, GIIN IRIS+ and Impact Frontiers are co-organizing the second annual IMM Convening, to be held on March 17–18, 2027 in Madrid, hosted by our Signatory COFIDES.


This two-day gathering will bring together advanced IMM practitioners from around the world. Rather than following a traditional conference format, the program is centered around participant-led sessions, peer exchange and shared learning.


  • Pre-register: Please register your interest on the IMM Convening website by Monday, November 30. Pre-registration doesn’t guarantee a place, but it does improve your chances of securing one. We’ll share more on the program and registration as planning continues and sponsorship arrangements are finalized.

  • Sponsorship: We’re also seeking sponsors to help make the 2027 Convening possible. If your organization would like to support this gathering of the global IMM community, please explore sponsorship opportunities here.

For a sense of the topics discussed at this year’s event, please find the notes from the 2026 Convening here.


We look forward to connecting with many Signatories and partners in Madrid!
