Hermes Intelligence Welcomes New Chief Technology Officer and Chief Product Officer

In a significant move to enhance its strategic leadership, Hermes Intelligence, a trailblazing AI-native strategic intelligence firm, has appointed Karol Oleszek as its new Chief Technology Officer (CTO) and Sebastian Kaczmarczyk as Chief Product Officer (CPO). These key appointments come as a part of the company's broader leadership expansion that began earlier in March 2026 with the appointment of Daniel Sako as CEO.

Karol Oleszek brings to Hermes a wealth of experience accumulated over years at prestigious firms such as Goldman Sachs and Point72. His expertise lies in the development of data infrastructures and systems that support some of the most advanced investment operations globally. Sebastian Kaczmarczyk joins with a robust background in strategic product initiatives, having worked at Bain & Company and JP Morgan, focusing on bridging the realms of data, technology, and executive decision-making.

A New Vision in Intelligence

With these appointments, Hermes Intelligence is positioning itself to not only enhance its leadership but also to widen the scope of its innovative product offerings. The company is renowned for its flagship platform, Vextrum, which is designed to provide structured and continuous intelligence seamlessly without necessitating the usual search efforts clients typically experience. This ontology-based living knowledge system pivots the traditional norms surrounding data acquisition and usage, aligning with the concept of “Sight, not Search” that the company espouses.

Daniel Sako, the new CEO, expressed confidence in the strategic direction of the company, stating, “When creating something that fundamentally alters how intelligence operates, we need leaders with proven experience at the highest levels. Karol and Sebastian’s decision to join us reflects their commitment to a transformative approach in our industry.”

Oleszek emphasized the forward-thinking vision of Hermes, affirming, “The technology we’re developing is tangible, and the demand in the market is imperative. Seizing the opportunity to shape a new category in strategic intelligence is a rare privilege.” Meanwhile, Kaczmarczyk pointed out the urgency and relevance of their technological solutions, remarking, “In today's fast-paced environment, creating actionable insights without delay is essential.”

Acknowledged Expertise and Recognition

Hermes Intelligence has been recognized for its innovative contributions to the field, receiving the WatersTechnology Award in 2025 for Best Alternative Data Provider. As it continues to refine and expand its capabilities, the company caters to a diverse clientele spanning financial services, industrial sectors, and government organizations.

Headquartered in Tallinn, Estonia, Hermes Intelligence operates across several key European cities including London, Brussels, and Warsaw, enhancing its presence and accessibility to clients globally. The strategic placements of professionals from top-tier firms signify a serious commitment by Hermes to elevate the standards in the intelligence landscape.

Looking Forward

As Hermes Intelligence embarks on this new chapter, the integration of leaders with prestigious backgrounds like Oleszek and Kaczmarczyk is sure to foster innovative thinking and drive the company’s mission to revolutionize how intelligence is utilized across various sectors. With a focus on delivering intelligence that proactively meets the needs of users, rather than simply responding to requests, Hermes is poised to make significant strides in the AI and intelligence fields.
