"He knows Ataccama's customers, its technology, and its culture better than anyone, and he has been the driving force behind its AI transformation.

Recently, he directed digital marketing, internal AI roadmaps, and the flagship Ataccama ONE Agentic platform. "What our customers are asking for has changed," said Martin Zahumensky, CEO at Ataccama. "Two years ago, they wanted to know whether their data was clean, documented, governed and mastered. Now they want to know whether that same data can safely fuel an AI agent. That is the harder problem, and it is also the bigger market opportunity. My focus is clear: keep shipping, stay close to the customers who bet on us, and make sure that when an AI agent acts, enterprises can trust the answer because Ataccama is behind it."
