TAMPA, Fla. — Chargebacks911, a global leader in chargeback prevention and dispute management, announced Tuesday the appointment of Donald Kossmann as its new Chief Technology Officer (CTO). Kossmann, a globally recognized technologist and AI pioneer, joins the company after an exceptional decade-long tenure at Microsoft, where he most recently served as Distinguished Engineer and Vice President of Business Copilot.
Kossmann’s arrival marks a pivotal moment for Chargebacks911, as the company continues its mission to transform the post-transaction payments ecosystem through cutting-edge artificial intelligence (AI). Possessing more than 30 years of experience in computer science, AI, data systems, and fraud protection, Kossmann brings a rare blend of academic distinction and enterprise innovation to the role.
At Microsoft, Kossmann led several groundbreaking initiatives, including serving as General Manager of Fraud Protection and Managing Director of Microsoft Research’s Redmond Lab. He played a key role in the development of SQL Hyperscale and Microsoft Copilot Studio —two flagship products that define Microsoft’s cloud and AI strategy today. Before joining Microsoft, Kossmann was a Professor at ETH Zurich, a Visiting Professor at Stanford University, and co-founder of Teralytics AG, a Big Data startup powering behavioural insights across industries like retail, finance, and transportation. Kossmann also holds a Doctor of Philosophy in Computer Science.
“Payments are a pillar of civilization, but trust in digital transactions remains a fundamental challenge,” said Kossmann. “Chargebacks911 is on a mission to reinvent the future of payments with AI at the core. I’m excited to roll up my sleeves and work hands-on, solving hard problems with a team that is passionate about creating secure, scalable systems for the digital economy.”
Kossmann’s appointment underscores Chargebacks911’s commitment to advancing technology that prevents fraud, reduces friction, and restores trust between merchants and consumers. As CTO, he will spearhead the development of next-generation solutions that integrate machine learning, and real-time data intelligence across the company’s global platform.
“Donald’s decision to join Chargebacks911 is a resounding validation of our vision and direction,” said Monica Eaton, Founder and CEO of Chargebacks911. “He’s not just one of the top minds in AI and data systems—he’s a builder, a thinker, and a leader who understands how to move fast and make a real-world impact. We’re thrilled to welcome him aboard.”
With Donald Kossmann at the helm of its technology strategy, Chargebacks911 is poised to redefine how the world approaches chargeback management, fraud prevention, and digital trust in commerce.
