Altenar promotes Giannis Papakonstantinou to sportsbook product director

Altenar has strengthened its sportsbook product leadership team with the promotion of Giannis Papakonstantinou to director of sportsbook product. The appointment places an experienced company executive in a senior role focused on the continued strategy and development of Altenar’s sportsbook offering. The announcement was published by Altenar on August 25, 2026.

Papakonstantinou has been with Altenar for more than eight years and has developed extensive knowledge of the company’s sportsbook product during that time. His career progression has also given him direct exposure to the commercial requirements of operators working across different markets.

The new position brings those areas of experience together. As director of sportsbook product, Papakonstantinou will take responsibility for leading product strategy and development while working closely with Altenar’s internal teams and operator partners.

The stated objective is to further develop the sportsbook platform around areas including stability, flexibility and market relevance. For a technology provider serving operators across multiple jurisdictions, those priorities remain central to how sportsbook products are evaluated and adapted.

Giannis Papakonstantinou brings customer experience to product leadership

Before moving into his new position, Giannis Papakonstantinou joined Altenar as an account manager before later progressing to account management director. That career path gave him the opportunity to work directly with customers and build a detailed understanding of their operational needs.

The experience is particularly relevant to a product leadership role because operator requirements can vary significantly depending on market conditions, product expectations and the level of flexibility required from a sportsbook platform.

Rather than approaching product development solely from a technical perspective, Papakonstantinou’s background has involved regular interaction with customers. That gives him direct familiarity with the practical considerations operators face when implementing, managing and evolving sportsbook solutions.

Altenar said this combination of product knowledge and customer insight was an important factor behind the promotion. The company also highlighted the value of having leadership that understands both the existing capabilities of its platform and the areas where further development may be required.

Altenar outlines its product development priorities

In his new role, Papakonstantinou will lead Altenar’s sportsbook product strategy and development. This responsibility is expected to involve close collaboration with internal departments as well as operator partners.

The focus on stability reflects the importance of dependable sportsbook infrastructure for operators. Product availability, consistency and operational reliability can all influence how effectively a platform supports day-to-day betting activity.

Flexibility is another key consideration. Sportsbook operators may require different configurations, market adaptations and product features depending on their business model and the jurisdictions in which they operate. Altenar’s own platform materials describe its sportsbook as offering configurable functionality and flexibility for licensed operators.

Market relevance also remains important as sports betting technology develops. Operator expectations can change as customer preferences evolve and as new product capabilities become available. A product roadmap therefore needs to balance ongoing innovation with practical requirements.

This creates a broad remit for product leadership. Decisions must consider not only technical development but also how changes can support operator objectives and maintain a competitive user experience.

Antonis Karakousis highlights internal career development

Antonis Karakousis, director of operations at Altenar, said: “Giannis’ promotion is a great example of the opportunities available to people who grow with Altenar. Over these years, he has gained an exceptional understanding of our business, our operators and, most importantly, our sportsbook product.

“Having worked closely with customers throughout his career, he knows not only what our product can do today, but also what it needs to do next. That combination of product knowledge, commercial understanding and first-hand customer insight makes him ideally placed to lead the next stage of our sportsbook development.”

The comments frame the appointment as an example of internal progression rather than an externally recruited leadership change. Papakonstantinou’s move from account management into a dedicated product leadership position also demonstrates how experience gained through customer-facing responsibilities can inform broader technology and product decisions.

From an organisational perspective, such progression can help maintain continuity. A senior product leader who already understands the company’s platform and customer relationships can potentially contribute to a smoother transition between existing priorities and future development plans.

Giannis Papakonstantinou sets out the next phase

Giannis Papakonstantinou, director of sportsbook product at Altenar, said: “I’m excited to take on this role at a time when sportsbook technology is evolving rapidly and operators are looking for greater flexibility, smarter solutions and stronger opportunities to differentiate. We have a strong foundation to build on and I’m looking forward to helping shape the next stage of our product journey.”

His statement reflects the broader direction outlined in the appointment. For sportsbook suppliers, technology development is increasingly connected to the ability of operators to differentiate their offerings while adapting to market-specific requirements.

The role therefore extends beyond maintaining an existing platform. It involves identifying where product capabilities can evolve and how those developments can remain relevant to operators operating in different environments.

Altenar’s current sportsbook proposition includes configurable features, live betting functionality, Bet Builder capabilities and solutions designed for different deployment models. The company states that its sportsbook module is deployed across more than 30 regulated markets.

A partner-led approach to sportsbook development

Altenar said the appointment further reinforces its partner-led approach to product development. Under this approach, feedback and requirements from operators form part of the process used to shape the sportsbook roadmap.

That approach can be particularly valuable in a sector where the needs of operators are not uniform. Product functionality that is effective in one market may require adaptation elsewhere because of different regulations, commercial models or user expectations.

The company has previously positioned its sportsbook around configurable technology and market adaptability. Its public product information also emphasises support for licensed operators and the need to respond to changing regulatory conditions.

For Papakonstantinou, the promotion puts his accumulated customer and product experience at the centre of those efforts. His background means that the new role follows a progression from understanding individual operator needs to helping shape the wider product direction.

What the appointment means for Altenar

The appointment of Giannis Papakonstantinou represents a significant internal leadership move for Altenar’s sportsbook product function. It brings a long-serving executive into a position where customer experience, commercial knowledge and product strategy are directly connected.

The immediate emphasis is on continuing the development of the sportsbook platform while responding to the changing requirements of operators and players across different markets. Stability, flexibility and market relevance are positioned as key areas within that strategy.

The appointment also highlights the importance of product leadership within the wider sportsbook technology sector. As platforms become increasingly configurable and operators seek greater differentiation, companies need leadership that can connect technical development with real-world market requirements.

Conclusion

Altenar’s promotion of Giannis Papakonstantinou places an established member of its leadership structure at the centre of the company’s sportsbook product strategy. His more than eight years with Altenar and his progression through customer-facing roles provide a professional background closely aligned with the responsibilities of the new position.

The appointment is also notable because it combines continuity with a forward-looking product remit. Papakonstantinou already understands Altenar’s sportsbook, its operator relationships and the practical demands associated with different markets. His new responsibilities will now require him to translate that experience into product priorities and future development.

For Altenar, the move signals continued attention to sportsbook product evolution while maintaining a strong connection to operator requirements. For the wider industry, it illustrates how deep customer knowledge can become an important foundation for senior product leadership as sportsbook technology continues to change.
