Salestube Achieves Google Meridian Certification
31 July 2025Salestube has become one of the first companies in the CEE region to receive Google Meridian certification. This recognition confirms the company’s top-level expertise in Marketing Mix Modeling (MMM). As the only partner in the region certified by both Google Cloud and Google Meridian, Salestube offers a unique combination of technology, data, and advanced analytics.
The Technological Advantage of Open Software
As an independent technology partner, Salestube has spent years developing its expertise at the intersection of data, advanced analytics, and computing infrastructure, fully leveraging the potential of cloud solutions.
Meridian is Google’s latest advanced econometric model, built on an open-source philosophy. The transparency and flexibility of open software allow Salestube to tailor and evolve tools to fit each client’s specific needs – without locking them into rigid, vendor-dependent frameworks.
“This certification isn’t a participation trophy – it’s proof that we build models that fundamentally change how marketing decisions are made. Thanks to Meridian, our clients are achieving up to 25% savings in media budgets and doubling their ROI,” says Krzysztof Rosiński, Managing Partner and CTO at Salestube.
A New Level of Data-Driven Marketing
The combination of the Meridian model with the computing power and scalability of Google Cloud Platform marks a true breakthrough in marketing technology. Supported by real-time data analytics tools like BigQuery and the Vertex AI platform for building and deploying machine learning models, this solution delivers proven, fast, and accurate results. For businesses seeking tools that not only deliver precise analytics but also scale effectively and run continuously, this is a game changer – offering capabilities the market hasn’t seen before.
“This certification is a testament to the hard work and deep expertise of our Data Science team, with hundreds of successful projects and strong knowledge of the available technologies. The fact that we offer Meridian as our default solution is no accident – it’s backed by our confidence and experience. It’s a modern, highly effective tool that brings measurable business value and enables data-driven decision-making, not gut feeling” – says Małgorzata Miłkowska, Data Science Manager at Salestube.
sMMMart AI – From Data to Real-Time Decisions
Salestube not only successfully implements Meridian for its clients but also builds proprietary tools based on the model, enhanced through Google Cloud infrastructure. The latest solution is sMMMart AI, which combines Google-certified methodology with BigQuery and Vertex AI. It provides clients with automated MMM modeling, integrating data from all media channels and generating real-time budget recommendations – no more waiting weeks for analysis.
„Meridian and sMMMart AI enable marketers to make concrete, data-driven business decisions. These tools support the shift of marketing from a cost center to an investment with clear, measurable returns,” – adds Jacek Józwiak, Growth & Strategic Partnerships Director at Salestube.
Two Implementation Models, One Goal: Real Business Growth
Salestube offers two approaches to implementing Meridian: full model development from the ground up by a dedicated team of experts, or a consultative collaboration model in which clients’ internal teams gain access to knowledge, tools, and support to transform their marketing approach. Regardless of the chosen model, the goal remains the same – to make marketing more predictable, scalable, and profitable.
