Thumzup Media Corporation ("Thumzup" or the "Company") (NASDAQ: TZUP), a digital asset accumulator and advertising industry disruptor, today announced the appointment of Chris Ensey, CEO of Aligned, former CEO and COO of Riot Blockchain, and former Chief Technical Advisor of Gryphon Digital Mining (now American Bitcoin Mining Corp.), to its Board of Directors ("Board"), effective October 14, 2025. Ensey's appointment comes at a pivotal moment as Thumzup prepares for its planned merger with Dogehash Technologies, Inc. ("DogeHash") and accelerates its evolution into a diversified digital innovation enterprise.

A seasoned technology executive with more than two decades of experience in cybersecurity, infrastructure, and data center development, Ensey is uniquely positioned to guide the Company's next phase of growth. He currently serves as Chief Executive Officer of Aligned, a data and technology firm focused on GPU (graphics processing unit) cloud services for AI and high performance computing applications. Ensey also co-founded Gulp Data, a vanguard in data valuation and financing.

Ensey's career spans high-stakes roles across both public and private sectors. As COO and later interim CEO of Riot Blockchain, Ensey led strategic expansion and operational scaling during one of the most dynamic phases of the crypto market's development. His expertise has been tapped by companies like Marathon Holdings and Gryphon Digital Mining (now American Bitcoin Mining). He has played a significant role in the building of several of the earliest institutional mining organizations in North America. At BlueVoyant, SafeNet, IBM, SAIC, and Dunbar Security Solutions, he advanced large-scale cybersecurity and infrastructure programs that continue to influence industry standards today.

"Chris brings an exceptional track record in technology and risk mitigation, experience that aligns perfectly with Thumzup's evolving vision," said Robert Steele, CEO of Thumzup. "As we continue advancing towards effectuating the DogeHash merger and expanding our presence in the digital asset ecosystem, his expertise will be invaluable in guiding Thumzup's next chapter of growth and innovation.

"Joining Thumzup at this pivotal point in its growth presents an incredible opportunity to help shape the future of both digital marketing and crypto assets," said Ensey. "I look forward to helping advance its mission of uniting technology, creativity, and financial innovation."

Ensey's appointment demonstrates Thumzup's ongoing commitment to cultivating a Board with world-class experience across finance, technology, and digital assets. His perspective on security, scalability, and decentralized architectures will enhance Thumzup's ability to execute on its post-merger blueprint, positioning the Company for market leadership and sustained value creation.
