Demetri Themelis: The $75 Check That Skyrocketed Knock

Shiv Gettu sits down with Demetri Themelis, co-founder of Knock, who shares his journey from finance to entrepreneurship. Growing up in a Greek-American household where money struggles were frequent, Demetri developed an early drive for financial security.

After working as an equity sales trader at UBS during the financial crisis, he and his co-founder Tom took a leap of faith into tech. Through raw conversations about the three-year journey to their first $75 check, building product-market fit, and managing the emotional highs and lows of entrepreneurship, Demetri reveals how Knock evolved from a simple scheduling platform to a comprehensive CRM solution.
