Welcome to a special end-of-the-year series on Making Risk Flow as we count down the weeks to the end of 2025. The series is a collection of our top episodes from this year based on views, downloads, and overall engagement. Each Tuesday, we will re-release one standout episode as we build up to releasing our top fan favourite on the last Tuesday.

In this episode, host Juan de Castro sits down with Marcus Ryu, former CEO and current strategic adviser at Guidewire Software. Marcus shares his journey from management consulting to co-founding one of the leading software providers for the property and casualty insurance industry. He offers candid insights into the trials and triumphs of entrepreneurship, including pivotal moments such as navigating a competitive lawsuit and transitioning to the public markets.

A central aspect of Marcus's story is Guidewire’s contrarian belief in the power of vertical solutions. By developing mission-critical software tailored to the specific needs of the P&C insurance sector, Guidewire revolutionized how insurers manage claims, policies, and billing. Now a partner at Battery Ventures, Marcus discusses how his experiences at Guidewire inform his approach to investing in the next generation of startups. From the importance of customer-centricity to leveraging technology to solve real-world problems, this conversation is packed with actionable insights for founders and industry professionals alike.
