What You'll Learn
- The "Two-Week MVP" rule: why shipping fast beats polishing
- Exit timing: how he sold two products right before platform earthquakes
- Product portfolio strategy: no funding, no employees, just compounding small wins
The Story
Tony Dinh, a Vietnamese software engineer with 7 years of full-stack experience, quit his $9K/month job in Singapore in September 2021. No funding. No co-founder. No LinkedIn presence.
Two years later, he was making $130K-160K MRR with ~90% profit margins across 4 products.
The "Itch-Scratching" Product Philosophy
Tony doesn't do market research. He builds tools that solve his own problems — literally:
"If I feel pain using something today, I build a fix this weekend."
His first product took 6 months of development. It never shipped — he realized nobody wanted it.
His most successful product, Black Magic (Twitter analytics), took one weekend to build the MVP. It grew to thousands of paying users before he sold it — two weeks before Twitter announced its draconian API pricing that would have killed the business.
The Two-Week Rule
After the 6-month failure, Tony enforced a strict rule: every MVP must ship within 2 weeks. If it takes longer, the scope is too big. Cut features until it fits.
This constraint forces clarity. You can't build features "just in case" when you have 14 days.
The Exit Timing Instinct
Tony sold two products at suspiciously perfect times:
- Black Magic: sold two weeks before Twitter's API pricing change
- Xnapper: sold right before macOS added built-in screenshot enhancements
He didn't have inside information. He had platform risk radar — when a platform starts signaling that a feature category is "strategic," the indie developer window is closing.
