Build, Partner or Outsource? The Decisions Behind a Telco Advertising Business

A successful telco advertising strategy starts with a deceptively simple question: what does the operator genuinely need to own?

The opportunity is growing. European video advertising rose 19.6% to €34 billion in 2025, according to IAB Europe, while Connected TV in Europe is forecast to expand at around 11% CAGR through the early 2030s (Grand View Research).

But those assets do not automatically create an advertising business.

Telecom operators already have many valuable ingredients: subscriber relationships, household identity, distribution, screens, devices and, in some cases, advertising inventory and rich audience signals.  The challenge is deciding how to turn those assets into a scalable advertising proposition: what to build, what to access through partners, and what is better outsourced.

How Telcos Can Choose the Right Advertising Business Model

Before considering the ad tech stack, operators need to decide what advertising business they are trying to create.

Do you have inventory you can monetise directly? Do you have the permissions and consent framework needed to activate your audience data for advertising? Do you already have advertiser and agency relationships? Do you want to build those capabilities?

The answers will vary significantly.

A telco entering advertising may prioritise speed and lower-risk market entry. Another may have strong subscriber data and distribution but limited inventory, making a partner-led model more attractive. An established advertising business may instead need to simplify fragmented systems across linear TV, VOD, streaming and programmatic.

At Synamedia, we see these different starting points broadly as  Newcomers, Enablers, Modernisers and Aggregators. They are not stages every operator has to progress through. They simply reinforce a fundamental point:  one telco monetisation model does not fit all.

That diversity is already visible among Synamedia customers. Telekom Slovenije  is using Iris to create new local advertising opportunities on international TV channels. And with Vodafone, Iris enables pre-roll advertising to be inserted into on-demand content from a broadcast partner.

Understand what you already have

Before deciding what to build, operators should take stock of what they already control.

That might include:

• subscriber relationships and household identity;
• audience and viewing data;
• set-top boxes, apps and distribution;
• advertising inventory and commercial rights;
• broadcaster and content partnerships;
• advertiser or agency relationships;
• existing advertising technology and operations.

For many telcos, first-party data is particularly valuable. But data alone does not create advertising revenue. It needs to be translated into audiences that can be activated against relevant inventory, connected to advertiser demand and measured effectively.

The same applies to inventory:  inventory without demand is not an advertising business.

And operators do not necessarily need to own the inventory themselves. 

Orange’s agreement with M6 in France illustrates one model: M6 contributes the broadcaster inventory, while Orange provides distribution reach and audience-targeting capabilities based on its customer and viewing data. 

Deutsche Telekom offers another example. Its partnership around MagentaTV combines Telekom’s distribution, inventory and data with specialist ad-tech capabilities. Deutsche Telekom can also monetise its own inventory, including MagentaSport. 

The lesson is not that every operator should follow either model. It is that telcos can create value at different points in the advertising chain. 

Build vs. Partner vs. Outsource: The Ad Tech Decision Matrix 

For many operators, the build vs partner ad platform decision becomes easier once the commercial ambition is clear.

Some areas should remain firmly under the operator’s control: subscriber trust, data governance, customer experience and commercial strategy.

But  control does not necessarily require technology ownership.

Ad serving, SSAI and CSAI, programmatic integrations or measurement infrastructure require specialist expertise and continuous investment. Building these internally only makes sense when doing so creates genuine differentiation.

Similarly, an operator may choose to build its own advertising sales organisation or access demand through broadcasters, agencies, sales houses, SSPs and other partners.

A useful principle is:

Own what differentiates you. Partner where expertise and scale matter. Outsource where internal ownership would simply add complexity.

How Advertising Maturity Changes the Decision

The answer will also depend on the operator’s advertising maturity.

A. Newcomer:  may retain control of data and strategy while leaning on partners for technology, demand and operations.

B. Enabler:  may use subscriber identity, audience data and distribution to make partner inventory more valuable without becoming a media seller itself.

C. Moderniser:  may already have the pieces but need to unify campaign execution, audiences, demand and reporting.

D. Aggregator:  may require stronger control over inventory, partner rules and yield while still relying on specialist technology and demand partners.

The important point is not the label. It is recognising that the advertising infrastructure should reflect the business the operator is trying to build.

Why Telcos Should Not Underestimate Ad Operations

Technology is only one part of the equation.

Someone still has to package inventory, manage campaigns, optimise performance, reconcile reporting, access demand and maintain relationships with advertisers, agencies and content partners.

These are specialist capabilities.

IAB Europe’s 2026 research highlights this operational challenge, with only 17% of respondents running the majority of their campaigns across channels. This points to the difficulty of coordinating campaign execution across increasingly fragmented advertising environments.

Simply adding another isolated system or sales route will not solve that complexity.

Operators therefore need to ask not only what technology they need but also which operational capabilities genuinely belong inside the business.

Build Less, Own More Deliberately

The distinction between ownership and control is critical.

A telco can control its subscriber experience without building its own ad-delivery infrastructure. It can control how its data is used without developing every identity capability internally. And it can define monetisation rules while connecting to multiple external demand partners.

This is where modular ad-decisioning platforms such as Synamedia Iris can play a role. Iris supports campaign and inventory management, audience activation, ad decisioning, programmatic connectivity, forecasting, reporting and ad delivery while integrating with an operator’s existing technology and partner ecosystem.

The objective is not to impose the same architecture on every operator. It is to allow the technology model to follow the commercial model.

How Ready Is Your Telco Advertising Strategy?

Before deciding what to build, operators need a clear view of where they are today: the assets they control, their access to inventory and demand, existing technology, operational capabilities and commercial ambition.

There is no universal blueprint for telco advertising.

The question is not how much of the advertising stack a telecom operator can build. It is which parts genuinely need to be theirs.

Frequently Asked Questions About Telco Advertising Strategy

1. How can telecom operators generate revenue from advertising?

Telecom operators can generate advertising revenue by monetising their video inventory, subscriber relationships, first-party audience data and distribution capabilities. Depending on their assets and business objectives, they can sell advertising directly, partner with broadcasters and advertising platforms, or enable targeted advertising on third-party inventory. The right approach depends on their access to inventory, advertiser demand and operational capabilities. 

2. Should telecom operators build, partner or outsource their advertising technology?

Telcos should retain control of capabilities that create competitive differentiation, including customer relationships, data governance, commercial strategy and subscriber experience. Specialist technologies such as ad serving, ad insertion, programmatic connectivity and measurement can be accessed through partners, while selected operational functions can be outsourced. Modular platforms such as Synamedia Iris allow operators to choose the capabilities they need and integrate them with their existing technology and partner ecosystem. 

3. How can telcos monetise first-party data without owning advertising inventory?

Telcos can monetise their subscriber data and distribution capabilities by enabling more valuable advertising across broadcaster and OTT partner inventory. Using consented audience insights, privacy-safe identity matching and data collaboration technologies such as clean rooms, operators can support addressable targeting, audience enrichment and campaign measurement. This creates revenue opportunities through partnerships, targeting uplift and platform services without requiring operators to own or sell advertising inventory directly. 

4. What advertising technology does a telecom operator need to build an advertising business?

A telco advertising platform may require campaign and inventory management, audience activation, ad decisioning, ad insertion, programmatic demand connectivity, forecasting, measurement and reporting. The specific technology depends on the operator’s advertising business model, maturity and existing infrastructure. Modular platforms such as Synamedia Iris allow operators to access these capabilities while integrating with their existing systems and advertising partners. 

5. What are the different types of telco advertising business models?

Telco advertising businesses can be broadly grouped into four profiles: Newcomers, Enablers, Modernisers and Aggregators. Newcomers are entering advertising and typically need foundational technology and operational support. Enablers use subscriber data and distribution to increase the value of partner advertising. Modernisers unify fragmented advertising systems and optimise revenue across linear and digital environments. Aggregators manage inventory, data and demand across multiple partners to maximise yield. These represent different business models rather than stages of a fixed progression. 

6. How can telcos assess their advertising readiness and decide what to build?

Telcos should assess five key dimensions: existing advertising revenue, control over advertising inventory, subscriber data maturity, commercial ambition and internal operational resources. These factors help determine whether an operator should focus on direct advertising sales, data-driven partner monetisation, modernising its advertising infrastructure or managing a broader advertising ecosystem. Synamedia’s eGuide Unlocking Advertising Revenue for Telcos in the CTV Era, explores these four approaches and the opportunities available to operators at different stages of their advertising journey.
