Brad Van Schouwen
CFO of EQO
Van Schouwen has always been intertwined with the startup community. The ever changing and challenging world of startups has always interested Van Schouwen who loves the diversity of experiences that are inherent in the startup community. After 15 years of helping other organizations find the right footing in the world of business and finance, Schouwen decided it was time for him to make his journey. So when Schwarz Taylor, an old friend of his, began to get involved with EQO, Van Schouwen saw the opportunity to fill a need the company soon had. As EQO’s financial expert, Van Schouwen works hard to direct the company’s ability to fund their long term investment; an investment that attracted Van Schouwen to EQO. The bigger and broader goal that EQO has makes it stand out from other entrepreneurs he has worked with in the past and he wouldn’t change any part of his time working with the team.
