The Story
Rob built SuperX - an AI-powered tool that helps creators and founders grow on X (Twitter) by analyzing viral content patterns, suggesting optimal posting times, and generating content ideas based on what's working in their niche. The tool uses vector embeddings to find viral concepts and helps users systematize their content strategy.
Rob's journey to SuperX was paved with failure. He spent 2.5 years building 5 different products that made exactly $0. He was running out of money and hope. Then something unexpected happened.
Out of desperation, Rob wrote a vulnerable post on X about all his failures - the products that flopped, the money lost, the time wasted. That single honest post went viral with 150K views. Someone in the comments suggested he start a dev agency, and that comment turned into his first $3K client.
This experience taught Rob the power of building in public and authentic content. He started vlogging his journey, and one video about filming in public at Amsterdam airport hit 1 million views. He realized there was a system behind viral content - and that's when he started building SuperX to help others crack the code. The app now generates $13K/month.
