Key Points
- Papakonstantinou has served at Altenar for over eight years, progressing from being an account manager to Account Management Director, and was appointed to the position of Director of Sportsbook Product on 25 August 2026.
- This comes as a result of a period of intense activity at Altenar, which includes an SBC Americas Sportsbook Supplier of the Year award in June 2026, a Greentube deal that went live at Admiral Casino in the UK in August 2026, and an AGLC license obtained in July 2026.
- Altenar has opted to promote from within the company and not hire from outside, appointing somebody who knows much about operators in the company’s product development.
Product directors in sportsbooks are usually engineers or product managers. Giannis Papakonstantinou is not one of them. Giannis started his career at Altenar as an account manager, worked for many years directly with operators from various markets, and acquired all the skills in the field of sportsbook by observing the needs and shortcomings of operators. On 25 August 2026, Altenar announced that Giannis had been promoted to the position of Director of Sportsbook Product. The name is new; the experience behind it is eight years old.
From Customer Conversations to Product Leadership
Papakonstantinou joined Altenar as an account manager and progressed to Account Management Director before stepping into this role. That career path kept him close to operators, not to engineering roadmaps or product specs. His understanding of the sportsbook was built through the feedback, friction, and requests that come directly from the clients the platform is supposed to serve.
Antonis Karakousis, Director of Operations at Altenar, was precise about why that background matters: “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 phrase “what it needs to do next” is where the announcement stops being routine. Altenar is not just filling a leadership gap; it is placing someone who spent years hearing operator problems at the centre of its product decision-making. That is a deliberate signal about where the roadmap will be shaped from.
What He Walks Into?
This news is breaking at a very busy time for Altenar. The company had won the Sportsbook Supplier of the Year award at the SBC Americas Awards that took place in Fort Lauderdale in June 2026, thanks to the company’s efforts in North and Latin America. It also released news in June about its deal with Greentube for its sportsbook technology in Spain and the UK. By the end of August 2026, a live operator was already using the partnership between Altenar and Greentube, AdmiralCasino.co.uk using Altenar’s sportsbook technology offering pre-match and live bets, risk management tools, and an adaptable front-end platform.
However, North America has made it even more difficult for the company to make decisions. As a matter of fact, in July 2026, the Alberta Gaming, Liquor and Cannabis Commission (AGLC) approved the use of Altenar’s sportsbook technology in Alberta. The company will be ready when the regulated online gaming market in Alberta opens up. After Ontario, Alberta is the second Canadian jurisdiction to open up for regulated iGaming, with operators having to deal with a market where users should be attracted away from grey market sites. Such an environment is quite challenging for a sportsbook technology provider like Altenar.
The Reason the Internal Hire Matters
Altenar could have brought in an external hire. Senior product executives move between B2B sportsbook suppliers regularly, and the sector has no shortage of candidates with product management credentials. The decision to promote from within, and specifically from account management, says something about how Altenar intends to approach the next stage of its product development.
It is clear from Papakonstantinou’s own statement about the challenges that he will face in the new role, which include “the changing nature of the landscape in which we operate in sportsbook technology and our need for more agility and differentiation”, that he sees himself ready for the challenges, and has great ambitions for the future of the company’s products.
The word “differentiate” carries weight here. Most B2B sportsbook platforms offer comparable core functionality. Where suppliers actually separate from each other is in configurability, local market tuning, and how quickly they respond to what operators need in specific jurisdictions. A product lead who spent eight years gathering that feedback directly from operators starts from a very different position than one who approaches the platform from a purely technical angle.
The Expansion Context Behind the Appointment
Altenar now operates across more than 30 countries and holds regulatory approvals across multiple jurisdictions, including Malta, Romania, Great Britain, Canada, Sweden, Denmark, Greece, South Africa, and Peru. Managing a platform across that regulatory spread means the product has to flex constantly. Compliance requirements differ. Player behaviour differs. Competitive conditions in a newly regulated market like Alberta are nothing like those in a mature market like the UK.
This is precisely why the appointment of someone who navigated those differences through operator relationships, rather than through internal product documentation, is notable. The UK launch with Admiral Casino, the Alberta regulatory clearance, the Greentube partnership, all of these demand a product lead who can prioritise what actually matters in each market rather than defaulting to what the platform already does well.
As far as Papakonstantinou’s priorities in his new post are concerned, they include platform stability, flexibility, and relevance in the market. These three points correspond to the main concerns voiced by operators in relation to sportsbook software providers, which include poor performance during peak times, high cost of customisation, and delays in localisation relative to regulatory changes. It remains to be seen whether progress will be made in these matters under his new post, but one thing that is clear is that Altenar has decided to appoint an experienced person to its product at the right time.
Expert Analysis
We think this appointment is more instructive than most leadership changes in the B2B sportsbook sector, and here is why. The instinct at many suppliers, when building out product leadership, is to hire someone who has built or managed products elsewhere. That brings external experience, but it also brings assumptions about what operators want that may not match the reality of Altenar’s specific client base and market footprint. Papakonstantinou brings the opposite; eight years of hearing what Altenar’s operators actually asked for, where the product disappointed them, and what would have made the difference. That is hard knowledge to replicate from outside. The timing of this promotion, sitting directly alongside the Alberta approval, the UK sportsbook launch, and the SBC Americas win, suggests Altenar is not making a quiet internal reshuffle. It is placing its most operator-informed person at the front of a product cycle that now needs to perform across several new and demanding markets simultaneously. The next 12 to 18 months will show whether that bet on insider knowledge pays off.
