In 2025, the marketing, advertising, and AdTech sector in Spain reached a clear turning point: the definitive transition to a model in which technology, data and artificial intelligence are the main drivers of value in M&A transactions (the buying and selling of technology companies).
Following a period of valuation adjustments, the market has regained strong momentum, driven by two key factors:
- The transformation of agencies into scalable technology platforms
- Pressure from investors and large corporations to acquire capabilities in data, automation, and AI
In this context, business operations are no longer driven solely by growth, but by strategic positioning within the digital ecosystem.
Growth in Advertising M&A by 2025
M&A activity in the advertising sector in Spain has evolved into a more sophisticated model. Companies are no longer simply buying up business volume, but rather critical assets needed to compete in a technology-driven environment:
- Skills in Artificial Intelligence applied to marketing
- In-house MarTech and AdTech platforms
- Access to international markets
- More efficient and scalable business models
This change has raised the bar in the acquisition processes of technology companies, where due diligence is no longer solely financial, but also technological, operational and strategic.
For shareholders valuing a sale of their technology business, this presents a clear opportunity: companies that incorporate proprietary technology or data differentiation are commanding significantly higher valuations.
Major M&A deals in the advertising sector in Spain (2025)
Atresmedia and Clear Channel: moving towards a fully omnichannel approach
One of the most significant deals of the year has been the acquisition of Clear Channel España by Atresmedia.
Strategic key points:
- Integration of out-of-home advertising (OOH/DOOH) with TV and digital
- Strengthening our omnichannel presence
- The integration of programmatic technology into the physical environment
Esta operación refleja una tendencia clara: la convergencia entre traditional media and advertising technology, a factor that is playing an increasingly decisive role in M&A processes. We discussed the details of this deal in our analysis published in September 2025.
t2ó ONE and Fly Me to the Moon: creativity + data as a competitive advantage
The acquisition of Fly Me to the Moon by t2ó ONE, in which Baker Tilly acted as exclusive financial adviser to the seller, exemplifies the prevailing growth model: the integration of complementary capabilities.
Strategic rationale:
- Combining data-driven performance marketing with high-impact creativity
- Developing a ‘full-stack’ solution for the advertiser
- Standing out in an algorithm-driven world
Transactions of this kind are becoming increasingly common in the sale and acquisition of agencies and technology companies, where value lies in the combination of creative talent and analytical skills.
Seaya acquires Adsmurai: the rise of Private Equity in MarTech
La inversión de Seaya's investment in Adsmurai confirms the growing interest among private equity firms in technology companies operating in the advertising sector. Key factors:
- Scalable technology platform for campaign management
- Strong focus on automation and AI
- International reach
For investors, the appeal is clear: business models offering recurring revenue, scalability and a strong technological component – three essential elements in any process of acquiring a technology company.
LLYC: international consolidation and strategic focus
LLYC has continued to pursue its strategy of inorganic growth, combining international acquisitions with selective divestments. Strategic focus:
- Growth in key markets such as the US
- Specialisation in high-margin sectors
- Building a global platform
Such moves reflect a significant trend in M&A: not just growing, but optimising the asset portfolio to maximise value.
Merger of independent agencies: gaining scale to compete
The consolidation of independent agencies is a response to structural market pressures, driven by the need to grow in order to compete with large groups, gain access to higher-volume clients and have the capacity to invest in technology.
In many cases, these transactions are a preliminary step towards broader processes involving the sale of technology companies or the entry of investors.
AdTech and MarTech: the real driving force behind M&A
The advertising sector is now inextricably linked to the technology sector. In fact, many of the most significant projects stem from the intersection of IT consultancy and marketing. Clear examples include:
- Technology consultancies acquiring agencies to control the entire sales funnel
- AdTech platforms consolidating content and distribution capabilities
- Vertical integration of technology, data and creativity
This has completely redefined the buyer profile: it is no longer just media groups, but also investment funds and technology companies.
Venture Capital: looking ahead to upcoming deals
Although the media spotlight is on major deals, venture capital remains key to understanding the future of the sector. Startups funded in 2025 share common traits such as the intensive use of AI and language models (LLMs), a focus on marketing automation, and lead generation using highly scalable models.
These companies represent a natural pipeline of future M&A deals. Over the next two to three years, many will be prime acquisition targets. For an M&A adviser specialising in the technology sector, identifying these trends is key to anticipating market opportunities.
Why is Spain leading the way in advertising M&A?
Spain has established itself as one of the most dynamic markets for advertising M&A in Europe for three main reasons:
1. Talent in technology and data
Spanish companies have swiftly embraced data and automation, creating assets that are highly attractive to international investors.
2. High market fragmentation
The existence of numerous independent agencies creates constant opportunities for consolidation and mergers and acquisitions.
3. Platform for international expansion
Spain acts as a natural bridge to Latin America and, in many cases, to the US, which enhances the strategic value of local companies.
In an environment where value lies in intangible assets—technology, talent, intellectual property—the role of the specialist adviser is crucial. The difference between a successful transaction and one that destroys value often lies in the ability to execute these stages correctly.
Greater focus and higher standards in 2026
Everything suggests that the trend towards consolidation in the sector will continue in 2026:
- Increased pressure on margins
- Increased investment in technology
- The growing importance of artificial intelligence in valuation
Companies that fail to evolve towards technology-driven models or achieve sufficient scale will struggle to compete. Conversely, those that combine data, technology and strategic positioning will continue to be prime targets in the buying and selling of technology companies.
M&A activity in Spain’s advertising sector is currently at a particularly exciting juncture. The combination of technology, consolidation and available capital is creating an ideal environment for shareholders looking to sell their tech companies, firms seeking to grow through acquisitions, and funds aiming to establish a foothold in the AdTech and MarTech ecosystem.
The key lies in understanding that the market has changed; it is no longer just about size, but about technological capability and strategic positioning.
