Mr. John-Williams previously served as Head of Finance and Strategy at Valmis Robotics, Inc., a startup company based in Bethesda, Maryland, where he led investment decisions, forecasting, and strategic planning to support growth opportunities. Prior to that, he was Vice President and CFO of Pandora Jewelry’s North American Business Unit, overseeing strategy, financial reporting, pricing, and M&A activities for the $1.4 billion revenue division.

“I am pleased to announce Mr. John-Williams as our new CFO. His leadership experience spans Fortune 500 companies, international publicly-traded corporations, and, most recently, startups,” said Ryan Pratt, Founder and CEO. “I am looking forward to working with Mike as the Company continues to execute on its strategic plan, grow sales, reach profitability and uplist to a national securities exchange.”

"I am excited to join Guerrilla RF at such a pivotal time for the Company," said Mr. John-Williams. "Guerrilla RF’s reputation for innovation and excellence in RF and microwave solutions, and its experienced leadership team, present an incredible opportunity for me to join a company with a strong foundation and support the Company’s future growth. I look forward to contributing to the Company’s continued success and working closely with the talented management team to deliver value for all stakeholders."

“I am sad to see John retire, but happy for him as he plans to spend more time in retirement with his wife, who also recently retired. John started with Guerrilla RF in 2016 as a fractional CFO, later becoming our first full-time CFO as sales and financial complexity increased when we took the Company public. John helped us grow revenue 20 times from $750,000 per annum to over $15 million during his tenure,” said Pratt. “Guerrilla RF has been very fortunate to benefit from John’s experience and guidance during an eventful period for the Company.”
