What our clients say

Our collaboration is highly professional, and the personal support paired with deep specialist knowledge won us over.

We particularly appreciate the communication on equal terms together with the pragmatic, solution-oriented implementation.

Their expertise in the ‘Google jungle’ is at a very high level, which gives us a suitable alternative solution for (almost) every question. We value the personal collaboration with our contact person, who, in addition to his specialist knowledge, has developed a good feel for our structure and needs over the years.

Whether by email or in meetings, communication is prompt and very flexible, which makes coordinating our service providers much easier for us.

We greatly value our collaboration with the Analyticsfreaks. Particularly noteworthy is their deep understanding of our business model, which feeds directly into the development of the GA4 and GTM setups. The Analyticsfreaks don’t just help think requirements through—they proactively challenge them to find the best possible solution. As part of our B2C website relaunch, they precisely managed the migration of our extensive tracking—from strategic analysis to technical implementation in GTM. The partnership is characterized by a high level of expertise and uncomplicated, close collaboration. Thanks to regular, direct communication and the necessary flexibility, we can manage our projects very precisely. A professional collaboration on equal terms with real added value.

Ilja Blonstejn

Digital Marketing Manager, Vaillant

Since 2022, Maria, Tim and Marina have been working alongside us on our major analytics initiatives—whether the switch to GA4, server-side tracking or major Shopify updates—and supporting us in continuously optimizing our web and app tracking. Above all, we value the team’s consistently up-to-date know-how and the way they work: always positive, fast and forward-thinking. You can simply tell that the team is passionate about the topic and understands our goals. That’s exactly how it should be!

After migrating our online store to a new platform, we had quite a bit of data chaos, which we brought to the Analyticsfreaks. After just a few short sessions, the Analyticsfreaks were able to analyze and also solve our problems very quickly—that was great!

We followed a recommendation from a partner (Klar) and turned to the Analyticsfreaks after the migration, and it was exactly the right decision.

After the firefighting following the go-live, we launched a project with the Analyticsfreaks to completely rebuild our tracking setup. We did so, and here, too, the collaboration was very efficient and solution-oriented. The project was completed on time with excellent results. When it comes to tracking, we would choose the Analyticsfreaks every time.

Karoline Kulosa

Director Digital and Ecommerce, ARMEDANGELS

After our website relaunch, we faced the challenge of setting up our analytics completely from scratch. The Analyticsfreaks not only supported us professionally but also implemented a precise and efficient tracking system in record time. We particularly value their ad-hoc support, which helps us quickly and reliably with any questions that come up.
We work with the Analyticsfreaks because their expertise in data analysis and web tracking is unmatched. No matter how complex our requests are, they always find a tailored solution. What we especially love is the consistently open and transparent communication. All projects are discussed clearly and understandably, so we always feel fully in control.
Our collaboration is based on mutual trust and shared values—especially accuracy, efficiency and reliability. This strong foundation is the key to our success and makes the partnership with the Analyticsfreaks a real win.

Working with the Analyticsfreaks was really good from start to finish. Together, we were able to set up our event tracking properly, making our marketing activities more measurable and allowing us to adjust many processes ourselves in the future without much effort. Luisa and Tim were always easy to reach and helped us with minor change requests even after our project was completed. If we have any further areas to work on, we know where we are in good hands! 🙂

For the migration from Universal Analytics to GA4 and the switch to server-side tracking via Elevar, we needed expert know-how. The Analyticsfreaks won us over with their comprehensive expertise and focused approach. We were particularly impressed by their flexibility and proactive communication via Slack. Their solution-oriented and pragmatic way of working made the collaboration very pleasant. We will gladly use their services again in the future, as we are convinced of the quality of their work.

Simon Bertschingers

Head of E-Commerce, namuk

As a B2B company with various websites and applications, we find managing our digital marketing a challenge. The Analyticsfreaks help us bring clarity, understand the complex customer journey and—with a GDPR-compliant analytics setup, conversion tracking for our performance campaigns and reporting dashboards—make our marketing measurable and easier to manage. The collaboration is agile, proactive and solution-oriented—there is a shared ticketing system and, if needed, regular coordination calls with us or other stakeholders involved. And on a personal level, our contacts are top-notch too! It’s always fun to exchange ideas with them about new developments in analytics. All in all, highly recommended!

Tadej Krajina

Digital Marketing Manager, TESVOLT

The Analyticsfreaks developed a clean plan for us out of complete tracking chaos. From that plan, we developed priorities and worked through them systematically. In the process, Vivien and the team also found further ways to harmonize everything. What was it all for? Truly helpful reports and dashboards. The collaboration was always structured and solution-oriented, and we are very grateful that we now have a very solid foundation for further strategic decisions.

The Analyticsfreaks helped us make our digital initiatives and campaigns measurable. With a clear eye for what really matters. For us as a nonprofit organization in particular, it is crucial to use our limited resources effectively and in a targeted way. Thanks to the well-thought-out tracking concept, we now understand much better which online channels really work for our donors. We enjoy working with the Analyticsfreaks because they are true analytics experts, take a solution-oriented approach and respond flexibly to our needs. Communication is fast and clear. The team brings not only technical know-how, but also a good feel for our goals and challenges.

We had a solid GA setup, but we grew very quickly and wanted a fresh external perspective on everything. Where can we improve? What are we missing? What might we no longer need? Maria brought a competent, fresh outside perspective to our Google Analytics setup and data. Now I am completely satisfied with our setup and feel ready for the future!

Wiebke Wölfle

Team Lead Online Marketing, JobRad

We were looking for an agency that wouldn’t just put up a few dashboards for us and push everything through on its own, but one that would lay the foundations together with us so that we could truly understand and continuously improve our digital performance. The Analyticsfreaks achieved exactly that!

From the initial consultation to setting up our dashboards together and operational support: The collaboration is highly professional, structured and at the same time pragmatic and solution-oriented. We particularly appreciate the patience with which the team listens to our problems time and again and explains even complex concepts to us in a way we can understand.

And what makes it all special: The Analyticsfreaks are not only extremely competent, but also simply incredibly likable. Working together is not only effective, but also a lot of fun. And that on a topic you would otherwise expect to be rather dry.

Thanks to the Analyticsfreaks, we can now make well-founded decisions, take a data-driven approach to management and have built up real in-house know-how. For us, they are more than service providers. They are partners on equal terms. Thank you so much for that!

Arthur Niemczyk

Head of Marketing, Endriss

We have been working with the Analyticsfreaks for around two years now—and our experience has been consistently positive. Even during the selection process, we were convinced not only by their overall technical concept, but above all on a personal level. Working together is really pleasant, fast and uncomplicated. They support us exactly where we lack the necessary in-house expertise—whether with smaller analytics topics or when setting up a comprehensive tracking concept for our shop and website, including Google Tag Manager and event tracking. Coordination with third parties, such as our web agency, also ran smoothly and efficiently at all times. We know that we can rely on their statements and recommendations at any time—and we look forward to our continued collaboration!

Laura Peters

Head of Marketing Communications & Sales Support, OTTO CHEMIE

Since our switch back to Shopify Liquid, the Analyticsfreaks have been our strategic partner for a first-class data setup.

We needed an absolutely clean tracking foundation. The Analyticsfreaks solved this with a precise concept using GA and Elevar. Today, we have seamless conversion tracking and legally compliant consent management that finally ensures a reliable data foundation.

In addition to their expertise, we are especially impressed by the Analyticsfreaks’ professionalism, proactiveness and flexibility, which makes them a valuable extension of our team.

A partner we recommend without hesitation—and to whom we gladly entrust our data foundation.

Yves Lüthi

Head of Tech & Data, X-BIONIC

We have a fairly complex setup of lead gen and e-commerce portals and brought the Analyticsfreaks on board as a partner early on. From cookie consent and GA4 setup to CRM integration, Tim supported us very competently and efficiently.
Efficiency and a hands-on mentality were also decisive factors in our collaboration. Every single project was very good: structured, but without overload. And we were transparently informed about the status quo at all times via our own Slack channel. We particularly liked this pragmatic approach; even when challenges came up at short notice, the team was quick to step in. That’s why I highly recommend them to anyone who wants to put tracking in competent hands!

We are the right partner for marketing teams that …

… actively develop their digital channels, want to work in a more data-driven way and see analytics as a long-term foundation for better decisions.

Digital touchpoints that matter

Your digital channels have a significant impact on revenue, leads, growth or customer experience. Better data can make a real difference here.

Growing marketing complexity

Your team coordinates multiple channels, tools, markets, stakeholders or agencies and needs a reliable data foundation to manage this complexity with confidence.

Commitment to long-term development

You do not see analytics as a one-off setup but as infrastructure that must be continuously reviewed and improved.

Collaboration that strengthens your marketing as a whole

Silos should never stand in the way of successful marketing. That is why we work closely with our clients’ agencies and partners on the basis of trust—whether in SEA, social media, SEO, shop development or IT. The voices of our partner agencies show how this collaboration works in practice.

  • Eshop Guide
  • The Data Institute

I was looking for someone who could set up all the tracking for my projects and also extend it. The results and the collaboration were one of a kind. When it comes to her way of working, Maria is second to none. Not only does she get an overview of the challenges super quickly, she also has an incredibly well-structured way of working, which makes the collaboration simply so much fun. Maria is the absolute analytics goddess!

The Analyticsfreaks are our number one point of contact for all questions about tracking. Whether for us or for clients, the Analyticsfreaks always have the correct answer within a short time. A high level of expertise and super communicative. Always fast, friendly and on equal terms. We are very happy to be a partner of the Analyticsfreaks.

Dominik Löwisch-Rückstein

Sales Manager & Partnership, Eshop Guide

I was super satisfied from start to finish. The Analyticsfreaks did a fantastic job, provided clear documentation, explained everything super clearly, and always thought pragmatically. Really, really great!

As a Shopify agency, we work on complex client projects and regularly rely on collaborating with professionally run partner agencies. Maria and her team at Analyticsfreaks are always a competent and reliable partner when it comes to taking our clients’ online marketing to the next level. Communication runs smoothly at all times, and working together is simply fun.

When I first came into contact with the Analyticsfreaks, I was skeptical. My clients’ tracking problems are often extremely tricky because I want to implement tracking solutions that no one has implemented before. The usual agencies were mostly overwhelmed by them or even had less expertise than I did.

However, the Analyticsfreaks quickly proved me wrong. Their expertise is impressive, and their ability to master even the most complex technical challenges has left me lastingly impressed. I was particularly convinced by their clear and professional communication and their deep understanding of the latest developments in tracking technology. There were never any misunderstandings, and they always found pragmatic, reliable solutions without overpromising.

I recommend the Analyticsfreaks to any e-commerce business that needs more than just standard revenue tracking in a search system and is looking for a long-term, accurate and reliable solution. The experts at Analyticsfreaks are worth the money and a good investment in peace of mind and efficiency.

As SEOs, we love working with data. To make sure it is always valid, we rely on the expertise of the Analyticsfreaks. Whether it’s tracking setup, data analysis or troubleshooting—when it comes to GA4, Maria and her team are our first point of contact. They make collaboration easier for us by working directly in our task management system and communicating proactively on every task. We particularly appreciate having two dedicated contacts at our side who, over time, have developed a deep understanding of our questions and challenges.

At adtree, premium quality comes first. We work exclusively with the best in their respective fields. We met the Analyticsfreaks two years ago and have been impressed by their expertise ever since. Their offering completely won us over!

I have been working with the Analyticsfreaks consistently for many years and it is always great! When it comes to questions about Google Analytics, they are my go-to experts. They have the know-how, work in a structured and professional way, and best of all, they also enjoy it—you can tell. Recommended without reservation!

Beyond a certain level of complexity, tracking becomes a nightmare for any performance marketing agency. The Analyticsfreaks are our secret weapon when things get tricky. Whether it’s Shopify, GA4 or a custom setup—thanks to their expertise, every client onboarding becomes a breeze. Thank you for the collaboration built on trust!
