About Brad Stillman

Brad Stillman is Chief Technology Officer at Sunflower Bank, N.A. Location: Greater St. Louis, United States.

I am a senior executive who transforms organizations, merges teams, and creates impactful technology solutions. Throughout my career in fintech and payments, I have led large-scale projects ranging from AWS migrations to tech stack upgrades. My peers describe my leadership style as collaborative, people-first, and empathetic, a high-energy talent magnet that people want to work for. By fostering an environment where diverse ideas and experiences spark innovation, I have consistently delivered tangible results for global markets. One of my key strengths is unifying stakeholders across multiple functions and regions. I believe the most successful initiatives arise when everyone feels invested in the outcome, so I work tirelessly to build consensus and influence beyond my direct remit. I show the “how” and get people to rally around the “why,” whether modernizing legacy platforms or designing proprietary payment solutions. I maintain a laser focus on operational excellence and customer experience, saving organizations millions in annual expenses, reducing employee turnover, and sparking innovative ideas that reshape entire lines of business. Even under high-stress situations, I remain calm and drive swift resolutions that keep teams aligned and motivated. I have also dedicated significant effort to training and mentorship, writing hundreds of internal courses and guides to build up talent pipelines. By nurturing a culture of continuous improvement, I have seen teams increase productivity, minimize defects, and take greater ownership of their work. My ultimate goal is to keep elevating organizational performance while offering opportunities for professional growth at every level. As I look ahead to senior leadership roles such as Managing Director, CIO, or COO, I remain committed to championing innovation, inspiring diverse teams, and delivering enduring value to both clients and stakeholders.
