Jamie Wilmsen is a Partner and Co-Founder of WILsquare Capital.

His entrepreneurial management experience across a variety of industries and disciplines allows him to draw upon a unique set of experiences and understanding to work with business owners and management teams to drive organizational growth and accelerated profitability.

From 2008 to 2014, Jamie was the Chief Operating Officer and Chief Financial Officer of a technology infrastructure company owned by successful entrepreneurs. He was instrumental in positioning the business for sale and guided the company in the transition from entrepreneurial-owned to a professionally structured enterprise that ultimately sold to a larger, Private Equity-backed regional service provider.

Jamie also served as the Chief Financial Officer of a telecommunications network provider where he successfully restructured the accounting and finance team to be more closely aligned with the accelerating growth of the business. Jamie played an active role in securing a $272 million credit facility from a syndicate of both traditional banks and large institutional asset managers in support of future growth.

Jamie’s past experience includes Co-Founder and Managing Partner of an award-winning, experiential retail concept, successfully raising Series A capital then navigating the small company through the turmoil of the 2008/2009 recession and eventual sale in 2012. In addition, Jamie was President of a family-owned consumer products manufacturing company, receiving Walmart’s Vendor of the Year Award and Target’s Vendor Excellence Award on three occasions.

Jamie is a Certified Public Accountant (non-active) with an MBA from the Wharton School of the University of Pennsylvania.
