Sharpest disagreement ▶ 23:10 Pushing back against the myth that VC is only for software

The guest passionately dismisses modern venture assumptions, declaring that the valley is called Silicon Valley, not lines of code Valley, and calls out investors for forgetting its hardware roots.

 Hardest push from Sean ▶ 17:35 Host challenges guest's strict 3x margin threshold

The host pushes back against the guest's rigid 3x threshold by bringing up an actual startup achieving a 40 percent reduction to test the boundaries of the framework.

 Biggest teaching moment ▶ 15:10 Masterclass on brownfield capex inertia

The guest explains why clean-tech parity pitches fail with brownfield facility operators because adopting parity forces the write-off of hundreds of millions in productive capex.

 Sean holds their own ▶ 22:50 Host contrasts deep tech diligence with standard software metrics

The host demonstrates sharp knowledge of standard venture diligence practices, identifying how software investors rely heavily on surface commercial metrics like ARR and churn.
