Salestube Enters the UK Market: Another Step in Group One’s International Expansion
19 May 2025Salestube is opening a new office in London – the European hub of advertising and technological innovation. The expansion into the UK market is part of a joint venture with Mediaplus UK, an agency owned by Group One’s long-time partner, the Serviceplan Group.
A New Chapter of Growth in a Strategic Market
As part of its international growth strategy implemented over the past two years, Salestube continues its global expansion. Following its entry into the US and APAC markets in 2024 and the launch of its German branch earlier this year, the company is now entering the United Kingdom. This move is intended to accelerate business scaling to the next level. The UK advertising market is currently valued at around £45 billion, while the Polish market is worth close to £2.5 billion (PLN 13 billion). UK e-commerce stands at £160 billion annually, compared to Poland’s £25 billion (PLN 130 billion). Additionally, the UK market is characterized by a high level of maturity, including digital maturity.
Salestube will leverage the local infrastructure, expertise, and client base of Mediaplus UK (formerly Total Media, acquired by Mediaplus Group in 2024 and rebranded in March 2025). The new Salestube branch will focus on delivering advanced MarTech solutions to British brands, particularly in the areas of Google Marketing Platform (GMP) and Google Cloud Platform (GCP).
“Entering the UK market in partnership with Mediaplus UK is a natural step toward building our global presence. We’re combining our marketing experience and technological expertise – confirmed by numerous Google certifications – with Mediaplus UK’s local know-how and strong client relationships. This enables us to deliver unique added value in one of the world’s most competitive media markets,” says Marek Żołędziowski, CEO of Group One.
The launch of Salestube UK comes at a time when 36% of UK marketers plan to increase their budgets for the next financial year*. Digital marketing budgets are growing particularly rapidly*, aligning perfectly with Salestube’s offering centered around data, automation, and Google technologies.
Technology and Partnership as the Foundations of Salestube’s Growth
From the beginning, Salestube has been developed using only Group One’s own funds, with no external capital involved. The company has not relied on venture capital or private equity, which has enabled a flexible approach to management, decision-making, development, and investment in in-house capabilities. Today, Salestube is one of the top three most certified Google partners worldwide, with full product certification in the Google Marketing Platform. It also has the largest team of certified GMP trainers globally. At the same time, the company continues to invest in developing its proprietary technology tools.
“Salestube’s growth as a technology reseller now exceeds +26% year-over-year. The company aims to generate 75% of its revenue from this model. This is achievable due to the group’s close cooperation with major Big Tech players, steadily expanding its service offering with technologies from partners like Google, Meta, Microsoft, and TikTok. Simultaneously, Salestube is investing in proprietary tools enriched with AI components. These include sMMMart AI – built on the new Meridian engine – and YouTube Booster, which automates YouTube campaign optimization,” comments Joanna Czekaj, CEO of Salestube.
These strategic investments are revolutionizing how brands communicate with customers throughout the entire purchase journey. Salestube seamlessly connects data, creativity, and technology to drive brands’ sales performance.
In January, Salestube obtained the Google Cloud Platform specialization in Marketing Analytics, an official confirmation by an external auditing firm that its projects and tools meet stringent requirements for managing complex tech initiatives. The company also strengthened its international standing with GMP certification in the United States, proving its expertise in implementing and operating the advanced marketing tool Display & Video 360 – used by over 60% of American companies – and its deep understanding of the local market. Additionally, it holds Google Germany certification for GMP tools – Analytics 360 and Search Ads 360 – demonstrating its strong knowledge of both Google products and the neighboring tech and marketing markets.
Salestube already serves over 250 clients across 35 markets, including global brands such as Avon, BMW, and Haleon (GSK). Its strong position in the CEE region and dynamic growth across the US, APAC, and Europe confirms Salestube’s capabilities in scaling modern technology and marketing solutions internationally.
