A product becomes a tangible the moment software lets it keep learning after it ships — adapting to need and earning revenue from services that didn’t exist at the moment of sale. Tangibles is the strategic playbook for that shift.
This book is important at this time because the tech community has over-rotated so heavily toward software that it no longer appreciates the points being made here.
// WHAT'S INSIDE
From the hard truths of hardware to the business models that compound — each arc carries first-person cases and a framework you can run as a free tool.
Long lead times, capital intensity, and irreversible manufacturing — and why connected augmentation became a survival response, not a luxury.
Digital interfaces, connectivity and firmware-over-the-air, sensing and edge intelligence — and the power budget that decides where compute can live.
Cut the cost of being wrong before tooling and inventory harden the mistake: the Decoupled MVP and a seven-stage Lean Hardware Funnel with kill gates.
Buyers must grasp what kind of thing a product is. The Positioning Audit and the Three Axes of Disruption decide adoption before launch.
The expanded attack surface, the global regulatory baseline, and the societal costs — repair hostility, remote lock-in, data as liability — that become law.
The seven-layer Tangible Stack, recurring revenue and NPV, and the AI watershed that compresses the build loop and extends what shipped products can do.
