Kevin Tupy, Founder & Partner 

Kevin is a successful entrepreneur in Sioux Falls, SD. He started his career with Citi, where his career spanned seven years working various management positions supporting its Private Label Credit Card division. In 2001, he left the corporate world of business banking and founded Z Wireless, a Verizon Premium Retailer, with one mall-based kiosk in Sioux Falls, SD. Over the next 10 years, Kevin grew Z Wireless to over 100 locations throughout the Midwest. In 2011, Atlantic Street Capital partnered with him to grow the business to a national footprint. By 2016, the business had achieved the status of the largest Verizon Premium Retailer in the country with over 1,200 locations nationwide. Today, the business has rebranded as Victra and is now part of the Lone Star Capital family. He continues his dedication to the company he founded by maintaining a significant share of equity in the business and remaining involved in strategic initiatives.

In 2016, Kevin founded Cresten Capital Holdings, a private equity firm focused on real estate, operating companies, and alternative assets. Kevin is actively involved in each of his portfolio companies and works side-by-side with the teams to enhance revenue growth, increase operating leverage, improve cash flow margins and elevate customer loyalty. Today, Cresten Capital Holdings has invested over $100 million in its assets and continues to grow by partnering with local entrepreneurs and business people who share the same dedication and values that our firm was founded upon: A maniacal focus on driving value through market differentiation while maintaining an unsurpassed customer experience and company culture.
