Kevin O’Leary, the venture investor and “Shark Tank” personality, criticizes the idea of work-life balance for founders during a company’s early phase. Speaking on Harvard Business School’s “The Founder Mindset” podcast, he argues that there is effectively “no balance” in the first 36 months after launching a business. O’Leary frames his view as focused on the realities of building a company, suggesting founders should prioritize work far more heavily than standard work-hour norms. In comments reported by Fortune and Yahoo News, he characterizes the appropriate commitment level as working “25 hours a day, 8 days a week,” using the statement to emphasize his point rather than to present a literal schedule. The remarks align with O’Leary’s broader reputation for strong, performance-oriented guidance to entrepreneurs. The sources report his stance and the context of the podcast discussion, without indicating that he endorses any changes to law or regulation related to working hours.
