Selection
Why differentiated products beat commodity products
Commodity products face price wars. Win a small niche first — smaller size, lighter weight, lower cost, a better color or a specific use case
Factory · Supply
How much inventory should a factory ship for its first Amazon batch?
New stores typically get about 500 units of initial storage. Send 50-100 units per SKU, validate, then scale with data
Channels

Team · Operations
How many people should a new brand project team have?
A new brand project team is typically 4-6 people: lead, store manager, operators and support — roles first, headcount second
Profit · Data
