Amit Agarwal figured out something beautiful: people don’t need new tools, they need better ways to use the tools they already have. He built Gmail plugins that make inbox life just a little easier—and turned that into a $20 million-a-year business.
Why It Works
- Solves a clear pain point: people live in their inboxes.
- Built on top of an existing platform (Gmail = built-in user base).
- Tiny utility, massive reach.
- Simple pricing and frictionless installs.
Real-World Proof
- Boomerang for Gmail helps users schedule emails and raised over $1M in revenue early on.
- Grammarly started as a simple writing plugin and grew to a $13B company.
- Superhuman added speed and design polish to Gmail, now charging $30/month to obsessed fans.
Small tweaks to big platforms often win big.
