TK Kader, a seasoned SaaS founder and go-to-market strategist, delivers a focused masterclass on micro SaaS entrepreneurship. Drawing from his extensive experience helping founders build and scale software companies, Kader unpacks three distinct types of micro SaaS ideas that have real potential in today's market. This isn't abstract theory --- it's a practical walkthrough that connects business model design directly to market validation.
