As I opened my laptop at the end of the month and started tallying up expenses and income, I had a pretty wild realization: one of my side income streams didn’t just do well—it finally surpassed my actual 9-to-5 income. What’s crazy is I don’t even spend that much time on it anymore. It’s been steadily growing for a while, and if you implement this business model the right way, it can genuinely be life-changing. In this video I explain why a coding job, even a good one, has a ceiling. Promotions take years, the overemployment era is basically over, layoffs are happening, and job security isn’t what it used to be. The real way to get ahead is decoupling your time from your income—building something once and getting paid over and over again. For me, the most profitable coding business to start in 2025 is building and selling niche APIs. Apps need data (weather, nutrition, translation, transportation, news—you name it), and instead of rebuilding features from scratch, devs and companies would rather pay a small recurring fee to use an API that already solves the problem. I break down how to start small, pick a niche that’s on the come-up, list on RapidAPI for built-in demand, and price/structure endpoints in a way that actually sells.
