Indeed, there are two options in building a product: build, then sell or grow together. I see Product Owners prefer to go with the first option because of different reasons. What will be your getting started advice for the ones that will like to try the 2nd scenario of creating a stakeholder community that contributes to the definition of the product features?
Some Product Owners have a strong vision about their product, and I feel that for them, the first strategy will be more suitable. But it is also dangerous as they might be wrong. What tools or processes do you recommend to use in this situation?
