Dylan’s entrepreneurial journey started unconventionally—after a failed college startup, he spent two years accumulating $30,000 in credit card debt while teaching himself programming and machine learning. This dedication helped him discover the massive gap in accessible speech AI technology and eventually get into Y Combinator despite having no product or traction.
In this video, Dylan shares why founder instinct matters more than market validation, and what it takes to identify a massive market opportunity before others see it and build technology that developers actually love using.
