Mobile technology company, Upstream, has strengthened its international management team with two key appointments. Kostas Kastanis assumes the role of Deputy CEO and Chrysa Karamanidi moves from her position as head of the company’s One-D platform to assume the role of Chief Innovation Officer.
As Deputy CEO, Kostas Kastanis will support in the execution of the company’s strategic direction to grow Upstream as the mobile operator partner that drives their digital growth maintaining direction over product and strategy. Kastanis joined Upstream in 2015 initially as Head of Strategy before taking on the leadership of its Zero-D platform. Prior to joining Upstream Kastanis worked with global consulting firm McKinsey & Company and also with Mastercard.
As Chief Innovation Officer, Chrysa Karamanidi will drive the performance of the company’s solutions and lead the evolution of the Upstream product roadmap in close co-operation with Kastanis. Karamanidi has held a number of roles within the company’s campaigns and digital marketing operations before becoming General Manager for LATAM markets. In 2018 she took over the leadership of the company’s One-D Digital Marketing solution and led the development and launch of new mobile operator products.
These two appointments further strengthen our leadership team and will help sharpen our strategic focus as we continue to expand our global business. During the past three years we have worked hard to transform our product portfolio and bring it to market. The early success of our new offerings has given us full confidence to move forward with our strategy.
