How would you determine the need for a platform?

To determine the need for a platform, I'd first clarify if we're evaluating an existing product or a new idea. For an existing platform, I'd assess product-market fit by analyzing key metrics like user retention (e.g., D1, D7, D30), engagement levels, and user feedback. Declining or stagnant retention, low engagement, and negative feedback would signal a lack of need or a need for significant pivots. For a new platform idea, I'd focus on identifying unmet user needs or pain points through market research, customer interviews, and competitive analysis. Validating these needs with potential users before development is crucial.
