Reading guide
Robin agrees with most of Hong Dashen’s views: startups must know their business, their customers, and how they make money. Early on, pass on people seeking freebies, merely comparing prices or asking questions, or lacking commitment. A loss-making sale can still make sense: printers, coffee machines, water filters, and game consoles sell the main product cheaply and earn money from consumables or services. Show your core differentiation, or become one vendor among many lined up for the buyer to choose the cheapest. His four points: clarify the model, define customers, make trade-offs, and avoid highly replaceable businesses.
Key points
- Make trade-offs about early customers to avoid unpaid work.
- A model can lose money on the main product and earn from consumables or services—illustrative examples.
- Core differentiation determines whether customers merely compare prices.
- Clarify the model, define customers, make trade-offs, and avoid weakly differentiated businesses.
