In this episode of C-Suite Secrets, Heather Parsons is joined by Sean Vassilaros, a seasoned entrepreneur and SaaS founder, for a deep conversation on trust, character, and what truly drives long-term business success.
Sean shares his entrepreneurial journey, from building and selling a highly regulated SaaS platform for remote clinical trials to advising university students and launching an HR technology company focused on one critical hiring question: can this person be trusted? Drawing from decades of experience hiring hundreds of employees, Sean explains why traditional interviews, references, and personality assessments fail to measure the most important predictor of success, character.
The discussion explores how trust impacts hiring, leadership, mergers and acquisitions, and company culture. Heather and Sean examine the rising challenges leaders face in a world shaped by AI, automation, and surface-level credentials, emphasizing the growing importance of critical thinking, integrity, and consistency between who someone is at work and who they are outside of it.
Sean breaks down how relationship-based data, observable behaviors, and peer insights can provide a more accurate picture of a candidate’s character than resumes or interviews alone. Together, they discuss red flags leaders should watch for, the financial cost of bad hires, and why hiring for values is no longer optional for founders who want to scale sustainably.
The episode closes with a candid reflection on leadership, accountability, and the long-term value of telling the truth, even when it is uncomfortable. This conversation offers founders and executives a thoughtful framework for building stronger teams, faster decisions, and more resilient organizations.
