Fandom as a retention engine, not a marketing skin
Strategic Advisor
Brian Selzer
I've spent 25 years helping organizations navigate platform shifts — from mobile and gaming to AR, spatial computing, and AI.
Most technology problems aren't technology problems. They're participation problems. The systems that succeed are the ones people return to, trust, contribute to, and ultimately belong to.
That's the work.

Attention into belonging
In Practice
Mobile broke the rules of desktop. AR broke the rules of mobile. AI is breaking the rules of everything.
I've shipped products through every one of those shifts. The lesson isn't the technology. It's that the human systems — the participation layer — have to be redesigned alongside it, or they collapse under the weight of the new medium.
