Aigner joins from fellow supplier Playtech Sports, where he was regional director emerging markets.
The move sees BetGames.TV CEO Andreas Köberl continue building his own team at the company, having himself been hired in October.
Köberl said: “Welcoming Thomas on board is a real coup for us. His experience and industry insight will no doubt prove invaluable for all of us at BetGames.TV – and I’m very excited to get started together.
“His hands-on mentality, authenticity and reliability are just the kind of values we encourage here, so he’ll fit right in as we continue our expansion globally.”
Aigner added: “I'm extremely eager to get started in this new challenge and help accelerate the great growth and success story of Betgames.TV, particularly in emerging markets.
“It's a great pleasure for me to be part of this team, with a host of award-winning products, more of which are coming in the near future. I have no doubt they will strengthen our position, keep us unique and most importantly at the forefront of new developments.”
