Sean Mullins

VP & CISO at Cass Information Systems

Before we meet, get clear on one question: what specific challenge am I facing that your product actually addresses, not features, but real challenges. I'm navigating regulatory expectations, board-level risk conversations, and a lean team all at the same time, and I'm looking for partners who understand that context before they walk in the door. Be clear about the problem you solve, be honest about where you're still growing, and that transparency alone will go a long way toward starting a real relationship.
