Danny McMillan returns after his longest break in almost
ten years, with Seller Sessions approaching its tenth
anniversary and roughly 1,300 episodes. This is the pilot of a new
monthly roundtable with Sim and Matt (Dorian returns next month),
moving away from the conversion show format towards raw
conversation.
You'll hear how Sim's team runs product development end to end
with AI: keyword-scored idea validation, brand director sign-off,
Claude-generated product concepts rendered through Codex, and a
launch pipeline already booked out to 2027. Matt shares how
Productpinion prioritises features from customer feedback, and why
prioritisation is the most undervalued skill in the AI era.
The back half tackles the big theme: cognitive
load. Danny breaks down verification fatigue, context
switching and AI maxing, and why the scarce resource is no longer
time but attention and decision quality.
Key Topics
- AI-driven product development - from
keyword scoring to Claude SVG concepts and Codex-generated product
renders
- Team structure at scale - how ideas route
through brand directors to sourcing across UK and Philippines
teams
- Hiring in the AI era - why refusing to
use AI is now a dealbreaker, and why gutting teams for AI is
commercial suicide
- Free local AI tools - Fluid Voice
(Whisper Flow alternative) and Meetily (Granola alternative)
- Cognitive load and verification fatigue -
the hidden tax of moving from doer to overseer

Key Takeaways
- AI has made product development fun
again - unique product concepts generated with Claude
and Codex, feeding a pipeline mapped to 2027.
- Augment, don't replace - if someone was
worth hiring, AI should multiply their output, not justify cutting
them.
- Prioritisation is the undervalued AI
skill - just because you can do everything doesn't
mean you should.
- Verification fatigue is real - build in
decision sprints and deliberate decompression, and reject Claude's
first plan on sight.
- The scarce resource is attention, not
time - your night schedule and recovery feed the next
day's output.
