Episode notes
From Side Projects To Full-Time Hit
- Brian Mueller started with Carrot To Do in 2013 and kept making small apps until Carrot Weather dominated his time.
- The success forced him to focus full-time on Carrot Weather and abandon making many new apps.
Personality As Product Differentiator
- The Carrot suite used a snarky AI personality to stand out against fake-positive gamification.
- That contrarian voice became the brand's defining differentiator across apps.
Let Users Tailor Tone
- Offer users settings to control personality intensity so the app fits broader tastes.
- Provide a professional mode for users who want no character-driven content.
