The demo is a weekend; the last 1% is years.
AI makes the demo nearly free, so the production system becomes relatively more valuable.
The classic power
A complex, embedded way of operating that competitors cannot copy even when they can see it. Helmer's example is the Toyota production system.
In the AI age
Anyone can build a ChatGPT-wrapper demo in a hackathon. The power is getting to 99% reliability on mission-critical work—KYC, loan origination, compliance—through years of unglamorous edge-case engineering that most teams, including the big labs, do not want to do.
Ask yourself
- Where does my product need to be boring and perfect? What separates my demo from a production system?
- What edge cases would take a competitor two or more years to discover and fix?
- Am I willing to do the unglamorous work of getting from 80% to 99%?
