From Building the Internet to Rethinking Mobile Connectivity: Christian Rouffaert's Journey

From helping build Europe's early internet infrastructure to founding a business transforming how organisations understand mobile connectivity, Christian Rouffaert's career has been anything but conventional.

As Founder and CEO of Teragence, Christian has built a business around combining data, engineering and commercial thinking to solve real-world connectivity challenges.

In this episode of The Route to Networking Podcast, he joins host Louis Parratt to reflect on his journey into telecoms, the decision to become an entrepreneur and why he believes the industry's future lies in making better use of the data already available.

From Finance to the Foundations of the Internet

Christian's introduction to telecoms came in the early 2000s, when the industry was undergoing significant change. Telecommunications markets were opening up, investment was accelerating and companies were building the fibre-optic infrastructure that would support the internet's expansion across Europe.

His first role was in finance, helping a company involved in constructing major European fibre networks understand its investment decisions. Although he wasn't working directly as an engineer, evaluating the commercial justification for these projects required him to understand the technology behind them.

Reflecting on the parallels with today's investment in artificial intelligence, Christian explains:

"Today, that capability is an AI capability. In those days, it was a network."

It was an eventful introduction to the industry, with the initial investment boom followed by a significant downturn.

"I rode the bust as much as I rode the boom."

His career subsequently took him to London and through roles with a traditional telecoms carrier, a hosting company and eventually management consulting, including Accenture.

Throughout those experiences, Christian discovered that his greatest strength wasn't necessarily specialising in one area but understanding how different disciplines connected.

"My skill or my USP or my calling card is that I can bridge between different domains."

Whether working across finance, engineering, marketing or sales, that ability to bring different perspectives together would eventually shape his approach to entrepreneurship.

Finding His Own Rhythm

Christian recalls a particularly memorable observation from a former manager at Accenture, who compared the organisation to a marching band, with everyone following the same tune.

Christian, however, was described as something rather different.

"You're kind of like a jazz player that plays jazz improvisations on a piano on the side of the road."

The comparison captured his experience of corporate life. He enjoyed complex, unconventional projects where he could connect different ideas, but found more structured environments restrictive.

He had often recognised opportunities to combine existing technologies or approaches in new ways yet struggled to pursue those ideas within larger organisations.

Eventually, he decided to act on one of them. Joking that his midlife crisis presented a choice between buying a Ferrari and becoming a start-up founder, Christian chose the latter.

There was no dramatic turning point, simply the realisation that it was time to stop discussing ideas and start putting them into practice.

That decision led to the creation of Teragence.

Turning Data into Meaningful Answers

Having worked across several areas of the telecoms industry, Christian had become convinced that operators weren't making full use of the information available to them.

Other industries had long relied on statistical techniques to forecast demand and improve commercial decisions. He believed telecoms could benefit from a similar approach, particularly as technology made it possible to process increasingly large datasets.

"I always felt that the telecom industry, although very technological and engineering driven, wasn't very clever in using data."

Teragence was built around combining crowdsourced information with advanced analytics to answer specific questions about mobile connectivity.

Rather than selling raw data, the company develops products that help customers understand where mobile towers are located, how signals propagate and what level of connectivity can be expected inside particular buildings.

"We create specific data products that answer specific points."

Another important difference is accessibility. Instead of requiring customers to purchase large datasets or commit to substantial contracts, Teragence offers more flexible, targeted solutions based on individual requirements.

For Christian, the objective is straightforward: turn complex information into practical answers that businesses can use to make better decisions.

Why Probability Can Be More Valuable Than Certainty

Traditional mobile network testing often involves specialist vehicles collecting detailed performance information across selected locations.

While highly effective, this approach can be expensive and time-consuming. Crowdsourced data offers broader geographical coverage, although the information is less detailed and requires statistical interpretation.

Christian believes understanding that trade-off is essential.

"Statistics is about probabilities, right?"

He explains that engineers are often accustomed to definitive answers, whereas statistical analysis works with confidence levels and likelihoods.

"It either works or it doesn't work. Is it good or is it not good?"

Crowdsourced analytics may not deliver absolute certainty, but it can provide highly useful guidance at a fraction of the cost of traditional testing.

To demonstrate the commercial benefits, Christian shares an unusual example involving robotic lawnmowers.

A manufacturer had developed GPS-guided lawnmowers that relied on mobile connectivity. However, some customers would purchase the equipment only for installers to discover that the signal at their property was insufficient.

Sending an engineer to survey every location before purchase was too expensive. Instead, Teragence provided an API that could check the expected mobile connectivity at a customer's address almost instantly.

For a small cost per check, the retailer could identify potential problems before arranging installation, helping avoid wasted visits, lost sales and disappointed customers.

The example illustrates a wider challenge Christian regularly encounters: businesses often accept connectivity problems as unavoidable because they don't realise there are tools available to address them.

Making Complex Technology Understandable

For Christian, developing sophisticated analytics is only part of the challenge. Communicating their value to customers is equally important.

He has enormous respect for the technical expertise behind mobile networks but recognises that not every customer needs to understand the engineering in detail.

Some want a comprehensive technical explanation. Others simply need to know whether their equipment will work at a particular location.

"You have to read your audience, right?"

He compares the experience to taking a car to a garage. Most customers don't need to understand every component of the engine. They want to know what the problem is, how it can be resolved and what it will cost.

The same principle applies to network analytics.

"We're going to tell you what you need to know."

Knowing how much technical detail to provide, and how to translate that information into something commercially meaningful, has become an important part of Teragence's approach.

AI, 6G and the Next Evolution of Connectivity

Looking towards the future, Christian believes one of the industry's biggest opportunities lies in the growing relationship between artificial intelligence and networking.

"I think the biggest thing now is the interaction between AI and networking."

As AI infrastructure evolves, traditional mobile tower sites could increasingly support smaller data centres and processing capabilities closer to where information is needed.

Deciding where that infrastructure should be located requires more than network engineering alone. Organisations must consider demand, power, land availability and connectivity.

Christian describes this as spatial intelligence.

"What goes where and why does that make sense?"

He also sees opportunities for AI to transform network optimisation, moving away from periodic manual adjustments towards systems capable of continuously responding to changing demand.

"That's where the action is going to be, I think."

As the industry progresses towards 6G, Christian expects this relationship between networks, data and AI to become increasingly important.

Unlocking the Data Operators Already Have

Despite the sophistication of modern telecommunications networks, Christian believes operators still have considerable opportunities to improve how they use existing information.

"The operators have a lot of data, but it always exists in very, very separate silos."

While data is already used effectively in areas such as customer segmentation and churn management, he sees further potential in network operations, cybersecurity and fraud prevention.

By connecting information across different systems, operators could identify suspicious activity, recognise unusual transactions and contribute to protecting customers across digital platforms.

However, Christian cautions against assuming that AI alone will solve these challenges.

"It's not just a matter of throwing Claude or ChatGPT at a bunch of data."

Information still needs to be organised, understood and interpreted correctly. AI may make analysis more accessible, but the quality of the results continues to depend on the data itself and the questions being asked.

"Garbage in is still garbage out, right?"

For Christian, the real opportunity lies in combining increasingly powerful tools with informed human judgement.

Building a Career Beyond One Specialism

Reflecting on his own experiences, Christian encourages people entering the technology industry to develop what he calls a T-shaped expertise profile.

This involves building deep knowledge in one particular discipline while developing a broader understanding of other areas.

"You know one thing very, very, very, very well, and then you know quite a bit of other things as well, and you can bring that together."

He believes this combination is particularly valuable in changing environments, where organisations need people capable of connecting ideas and approaching challenges from different perspectives.

His advice is to remain curious, recognise individual strengths and seek out workplaces where those qualities are appreciated.

Entrepreneurship has reinforced many of those lessons. When asked about the biggest surprise of starting his own business, Christian acknowledges that the experience has been far more demanding than he anticipated.

"It's much harder than you think and it's much tougher than you'd ever think."

But the rewards have been equally significant.

"It's also much more fun than you think."

He also highlights the importance of surrounding yourself with talented people, listening to their expertise and finding mentors who can offer guidance throughout your career.

And when Louis asks which skill everyone should develop, regardless of their role, Christian's answer is immediate.

"Storytelling."

Being able to explain what you're doing, how you're doing it and why it matters is a skill he considers essential, particularly when communicating complex technical ideas.

Connecting Ideas, People and Data

Christian's journey demonstrates that a successful career in technology doesn't always follow a predictable path.

From a finance role supporting Europe's emerging internet infrastructure to building his own analytics business, his career has been shaped by curiosity, adaptability and an ability to recognise connections between different disciplines.

As telecoms becomes increasingly intertwined with AI, digital infrastructure and cybersecurity, those qualities will continue to matter.

And when asked what single message he would like listeners to take away from the conversation, Christian returns to the subject that has influenced so much of his career.

"Work with data, understand data, see what you could learn from data."

It's a fitting conclusion to a conversation about recognising opportunities, challenging established thinking and finding new ways to make technology work for businesses and people.
