Episode notes
Solo-Built Extension Reaches Big Scale
- Saeed built SuperPower ChatGPT as a solo software engineer and launched it about 1.5 years ago.
- The extension reached roughly $20K–$30K MRR and ~270,000 downloads with ~150,000 weekly active users.
Build For Existing Platforms
- Build on existing large platforms like Gmail, Twitter, or YouTube to access users without heavy discovery cost.
- Or target niche marketplaces (Zoom, Salesforce) where fewer builders mean easier competition and higher conversion.
Marketplace Focus Eases Competition
- Competing on the open web is harder than in limited platform marketplaces where you face fewer direct competitors.
- Browser extensions are faster to validate since they run in users' browsers with minimal infrastructure.
