Episode notes
Distribution Became Castos’s Early Moat
- Distribution and trust can matter more than product quality when launching a software business.
- Castos gained both by acquiring a respected plugin with roughly 20,000 active installs.
Plan For Every Growth Channel To Plateau
- Treat every acquisition channel as temporary because growth eventually plateaus after exhausting its audience and keywords.
- Use a successful channel to build the next one before the curve flattens.
Higher Intent Beat Higher Traffic
- Castos saw traffic fall by about half while trials increased after shifting from broad informational content to high-intent pages and tools.
- Free browser tools attract visitors actively solving problems, such as extracting audio from video.
