You don't need to raise venture capital or build the next unicorn to create a profitable SaaS business. TK Kader makes the case for micro SaaS --- small, focused software products that serve niche markets with high willingness to pay and low competitive pressure. In this video, he walks through the characteristics that make a micro SaaS niche attractive: market size that's too small for big players to care about, customers with urgent, expensive problems, and distribution channels you can own without paid advertising. TK shares specific examples of profitable micro SaaS products from 2023, breaking down what made each one work --- from browser extensions that solve a single workflow pain to vertical SaaS tools serving industries like property management, legal, and healthcare. He also covers validation techniques that cost nothing, pricing strategies for niche products, and how to think about growth when your total addressable market is intentionally small. A must-watch for indie hackers, solo founders, and anyone considering the micro SaaS path.
