How to evaluate the idea of adding a marketplace to the product?

Assessing the idea of adding a marketplace to a product involves several key steps:

1. Market and user needs analysis — is there demand for a marketplace in your niche? What problems will it solve for users?
2. Business model evaluation — how will the marketplace generate revenue? Commissions, subscriptions, advertising?
3. Technical feasibility — how difficult is it to integrate a marketplace into the current product? What resources are needed?
4. Competitive analysis — are there similar marketplaces? How will yours be better?
5. Risks and limitations — legal issues, seller support, quality of goods/services.
6. Potential impact on current users — will the marketplace worsen the main user experience?

To make a decision, it’s useful to conduct an MVP, gather feedback, and evaluate key metrics (activity, conversion, revenue).
