Reading guide
Robin argues that addition is easy. Taiwanese consumers value getting more for the same price, so founders and product builders often keep adding features—a tendency he personally considers dangerous. He cites TA-Q-BIN, Tamagoya, and Yoshinoya as examples of doing one thing exceptionally well. Entrepreneurship requires subtraction: remove the unnecessary and focus attention on the most important problem. Startups’ advantages are flexibility, focus, and speed; giant platforms can be left to giant companies. Many startups stack AI, IoT, blockchain, cloud, big data, 5G, and NFTs until they can no longer explain their business in one sentence.
Key points
- Addition is easy; subtraction makes focus possible.
- Do one thing exceptionally well, as in the TA-Q-BIN, Tamagoya, and Yoshinoya examples.
- Startups’ advantages are flexibility, focus, and speed.
- Stacking fashionable technology terms makes it hard to explain what you do.
