Interaktiv has kindly renewed its Foundation sponsorship for 2018!

Sponsorships are the Foundation's only source of income, which we spend protecting Plone, promoting Plone through event marketing, and supporting its continued development through sprints (see the complete list of Foundation activities and how to become a sponsor).
