A Thessaloniki-linked software company is now powering supply chain operations for one of the world's five largest retail groups.
Dataviva, a company with US headquarters but strong development roots in Thessaloniki, has secured its largest client to date through an agreement with a major American retail corporation. The firm's software development and data science team is based in the northern Greek city, where founder and CEO Kostas Malamas also lives and works.
Speaking at a recent Open Coffee Thessaloniki event, Malamas described the agreement as a milestone project in global supply chain management, marking a new phase for the company following years of disruption in international retail, from the pandemic to the Russia-Ukraine war.
According to Malamas, Dataviva focused on what it does best during this period of instability: developing software for what he identified as the most complex supply chains, particularly those of large supermarket networks.
The company's platform is a low-code system for real-time planning and execution, integrating artificial intelligence to optimise product assortment, demand forecasting, supply chain operations and promotional strategies for retailers and manufacturers. Delivered as a Software-as-a-Service solution, it is designed for large organisations that must make frequent, complex decisions using large volumes of data.
Its next-generation software enables faster decision-making for complex processes while fully automating simpler ones, using AI and machine learning algorithms. The platform also centralises decision-making within organisations through a real-time planning interface, while managing large-scale automated optimisation and forecasting processes.
Dataviva was founded in 2020 as a spin-out of Veltio, a US-based retail planning consultancy established by Malamas in 2004. He later relocated to Thessaloniki to build the company's software engineering and data science team, which went on to form the core of Dataviva. The founding team had already developed advanced supply chain planning and optimisation solutions for leading global retailers for more than 15 years.
In 2025, Dataviva merged with Veltio, with the unified entity now operating under the Dataviva brand. Veltio has been rebranded as Dataviva Professional Services, effectively combining the company's platform with 2 decades of consulting expertise in demand forecasting, assortment planning, and supply chain optimisation.
