How I Started a SaaS Business from Nothing

TL;DR

Every SaaS business starts with nothing --- no product, no customers, no revenue. TK Kader takes you through his personal playbook for navigating that zero-to-one phase, sharing exactly how he built a SaaS company from the ground up. The video is structured as a chronological walkthrough: how he identified the problem worth solving, the lightweight validation experiments he ran before building anything, the decisions he made about the tech stack and MVP scope, and the scrappy customer acquisition tactics that landed the first 10 paying users. Kader is refreshingly honest about the false starts --- the features he wasted months building, the pricing experiments that flopped, and the moments he nearly quit. He also covers the operational side that technical founders often neglect: incorporation, contracts, payment processing, and support infrastructure. If you're sitting on a SaaS idea and don't know where to begin, this video replaces the vague "just start" advice with a concrete, step-by-step roadmap you can actually follow.
