Our vision

Data-powered growth, fit for an AI future. 

We are operating in a fast-changing landscape. The requirements of the market have fundamentally shifted. 

Decisions once based on instinct today must be grounded in data. CFOs are more closely involved in every investment and AI is rewriting what's possible and who gets to compete. 

NEXT15 is built for this moment. Our focus on data, technology and activation puts us exactly where the opportunity is. 

Built for what’s next 

Our advantage, by design 

There's no shortage of groups claiming to combine data, technology and creativity. Here's what actually makes us different. 

We own our data 

Most agencies buy data or license it. We build it. Savanta's BrandVue tracks 4,000 brands across 14 sectors, drawing on 9 million+ participant responses annually. SMG holds over £1 billion of retail media spend analysis. This proprietary data gives our clients competitive intelligence others can't access and insights that drive measurable commercial outcomes. 

We apply AI, we don't just talk about it 

AI isn't a buzzword for us, it's in production. Our platforms use it to deliver real efficiency gains: 

  • SMG's Smart Planning tool removes more than 50% of campaign planning time 
  • Pretzl's JourneyLab maps complex B2B buyer journeys using AI-driven modelling 
  • Savanta's virtual personas simulate audience behaviours at speed, reducing research cycles from weeks to days 
  • M Booth's GenIQ delivered a 5,000% increase in LLM brand mentions for one client within 90 days 

We lead in high-growth categories 

We are not generalists. We hold strong positions in Retail Media, Data & Research, Digital Transformation, Marketing and Communications, and Creative Services. Categories where demand is accelerating and AI adoption creates competitive advantage. 

SMG helped pioneer retail media in the UK and now manages over £0.5bn in campaigns annually, operating five of the UK's largest retail media networks. We help retailers build high-margin advertising businesses and help brands reach shoppers at the point of purchase, with the data to prove it worked. 

Savanta's proprietary data asset tracks 4,000 brands, draws on 9 million+ annual respondents, and incorporates AI-powered synthetic personas to accelerate insight cycles. We turn complex research challenges into clear commercial decisions. 

Transform helps public sector organisations and large enterprises design, build, and operate digital services that actually work. Our programmes have delivered for the Department for Education, HMRC, the Ministry of Justice, and more.

We help ambitious brands build reputation, relevance, and market position through data-driven communications, B2B marketing, and integrated campaigns. Our businesses include activate, Pretzl, M Booth, M Booth Health, MHP Group, and Marker.

Award-winning digital customer experience agency Brandwidth builds the digital foundations for CX transformation, creating connected, high-performing systems that deliver results. Growth studio ELVIS connects brands to new audiences through Serious Entertainment™.

We are unified, not uniform 

Our businesses share a platform, data infrastructure, and technology, but each retains its specialist identity and culture. Clients get focused expertise without losing access to the broader capabilities of the group. 

We measure outcomes, not outputs 

We measure success the way our clients do: revenue growth, market share gains, cost savings, and ROI. If we can't measure it, we don't claim credit for it. 

We attract people who build, not manage 

Our people are our biggest strength. We foster entrepreneurialism, bold thinking, and smart risk-taking. We're agile, we challenge the status quo, and we attract talent that wants to be at the frontier of what data and technology can do.

A collective of specialist agencies. Each one focused. Each one data-led. Each one positioned in a market that’s growing.
