Episode notes
Interview First, Monetize Early
- Do user interviews as a non-negotiable first step to deeply understand problems and previous solutions tried.
- Validate willingness to pay with paid waiting lists, presales, or MVP subscriptions before full build.
PhotoRoom's Focused Launch
- Daphne recalled PhotoRoom launching with one standout feature—background removal—and charging ~$8–$9 monthly early on.
- The focused beachhead let them expand later without trying to out-feature Photoshop initially.
Ship One Great Feature Fast
- Do aim to deliver a narrow, excellent first version rather than a broad, feature-heavy MVP.
- Keep presale timelines short (around three months) and manage expectations with transparency.
