One weekly brief on what changed in AI, written for the people who run marketing.

The stories that survived the week, what they mean for your work, and what to do before your next planning meeting.

I’m Guillaume. I write the brief and build the system behind it, with the work and the bill in public. I keep membership small so I can give each person proper attention.

If you think you should be here

Invitations come from members, and from me. If nobody has sent you one, say what you run and what you’re deciding this quarter — that’s the whole application.
