Altenar has strengthened its sportsbook leadership structure by promoting long-serving team member Giannis Papakonstantinou to the role of director of Sportsbook Product.
Papakonstantinou brings more than eight years of experience at Altenar, giving him deep institutional knowledge of the company’s sportsbook platform and its operator-facing requirements.
He originally joined the company as an account manager before progressing through the ranks to become account management director, building significant commercial and product expertise along the way.
Throughout his career at Altenar, Papakonstantinou worked closely with customers across multiple markets, gaining direct insight into their operational needs and expectations from the platform.
That hands-on customer exposure has positioned him with a rare combination of commercial understanding and technical product knowledge that few internal candidates could match.
In his new position, he will take responsibility for Altenar’s sportsbook product strategy and development, collaborating with both internal teams and operator partners.
Antonis Karakousis, director of Operations at Altenar, praised the appointment, saying it demonstrated the career potential available within the organisation for those who invest in their growth there.
Karakousis 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.”
He added: “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.”
Papakonstantinou himself commented on the pace of change currently reshaping the sportsbook technology landscape and outlined his ambitions for the platform going forward.
He 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.”
He continued: “We have a strong foundation to build on, and I’m looking forward to helping shape the next stage of our product journey.”
The appointment underlines Altenar’s broader commitment to a partner-led approach to product development, ensuring its roadmap remains aligned with the shifting needs of operators and players.
It also reflects the company’s ongoing focus on blending long-term industry expertise with continuous innovation across its sportsbook offering.
