Most CMO communities are membership networks built around marketing peers, content and events. They are useful for staying current with the craft. Open Future Forum takes a different angle: a small room where marketing leaders sit with the rest of the C-suite, because AI is reshaping how the whole company grows, not only marketing.
Broad global membership: CMO Alliance and the CMO Council. Frequent facilitated peer sessions: CMO Huddles. GTM training and cross-functional peers: Pavilion. A small Silicon Valley room inside a cross-functional community: Open Future Forum.

Most CMO communities are marketing only. Open Future Forum seats marketing leaders with the CFOs, CISOs, CTOs and CEOs they depend on, so growth is discussed across the company, not in a silo.
The format favors small, off-the-record dinners and focused panels over large stages, with the same giver standard that runs through Open Future Forum.
The agenda is AI and growth, not general marketing craft. Sessions connect marketing to the AI strategy the rest of the C-suite is running.
It depends on what a CMO wants. For a broad global network, CMO Alliance or the CMO Council. For frequent B2B peer sessions, CMO Huddles. For GTM training, Pavilion. For a small Silicon Valley room inside a cross-functional community, Open Future Forum. See the full executive AI communities comparison for the wider field.

Those are marketing-focused membership networks. Open Future Forum is Silicon Valley, free to qualifying CMOs and cross-functional, so marketing leaders meet finance, security, technology and board peers in the same room. It is AI-native.
Yes. It is the marketing vertical of Open Future Forum, a Silicon Valley executive community founded in 2019 that runs panel events and invite-only dinners for C-suite leaders.
Open Future Forum's CMO dinners are invitation-only and free to qualifying CMOs. If you lead marketing in the AI era, or know a CMO who should be in the room, we would like to hear from you.
