I managed the vendor selection for the PrePay solution and selected Aethos that Steve worked for. I also looked after the technical implementation and launch of the related services. I met him both during contract negotiations, and later, when he oversaw the delivery. He was very well-rounded technology wise and knew the GSM technology very well as well as the related Value Added Services. Even though we were all under tremendous pressure, I learned to trust Steve and the whole Aethos team. He was direct and franc, when needed but in a pleasent way. Very oriented to solve problems without any extra politics. Even during the most hectic times we respected each other for the genuine efforts to get things done, pragmatically. Besides, Steve was always fun to work with."
