Choose the customer before the product
Decide who is buying and why before deciding how many SKUs to launch.
Choose one clear use case
A product is easier to explain when the customer immediately understands when and how to use it.
Test willingness to pay
A technically good product can still fail if the pack size, price or positioning does not make sense.
Expand after evidence
Use the first product to learn about pricing, packaging, repeat purchase and feedback before adding variants.
