More testimonials
Excellent collaboration – highly recommended!
We worked with KplusA Communications to organize the Ex-CEO Leadership Excellence Day at the Steigenberger Frankfurter Hof, and we are completely thrilled with the results.
The collaboration was extremely professional from the very beginning: strong concept, transparent planning, and an organization we could rely on 100%.
On the day of the event itself, everything went smoothly, and the team had everything under control: setup and dismantling, technology, direction, and coordination.
Thanks to KplusA, the event was a huge success for our brand and provided us with valuable content and new leads.
We are therefore very much looking forward to organizing further events together in 2026.
Strong recommendation from our end!

Dr. Michael Stoermer
Really excellent work
I have had some very bad experiences with event agencies in the past, but I have to say that Kevin did an amazing job. After just one workshop, we were able to sharpen our vision and positioning significantly... We are now working together on several large projects, and KplusA is supporting us with the entire organization and strategy.

Antonia Nehring
KplusA understands and performs 🚀
I brought KplusA on board to organize a conference because I was looking for marketing support. The onboarding process was very focused and made me feel at home from the very first second. “They understand me here!” was my first thought. I was completely won over by the implementation of the homepage, branding, and templates for social media. I am delighted to go public with the result because it looks great, is appealing, represents me, and sells! Kevin and Johanna made it easy for me from the start, giving me exactly the support I needed. Lots of helpful tips and suggestions helped me with the planning and implementation or simply gave me the confidence I needed. The goal for the organization next year: to do even more work with KplusA.💪

Matthias Parey
Events on a whole new level
As a service provider, I regularly attend KplusA events – and I'm thrilled every single time. The professionalism with which they work is truly impressive. I've seen many events, both with and without KplusA – and honestly, the difference is huge. Whether it's the flow, look and feel, or mood among the participants – with KplusA, everything just falls into place. For me as a videographer and photographer, that's worth its weight in gold, because I can capture the best emotions when everything is running smoothly and people are in a good mood. And that's the standard at KplusA. The team is also fantastic: super organized,reliable, professional – you can tell that everyone here knows what they're doing. Unfortunately, you don't often find that kind of reliability anymore. Kevin Arenja is someone who thinks ahead. Fair in his consulting, extremely forward-thinking, and with a great feel for different industries. One thing is clear to me: if you want to put on a really successful event, KplusA is the right choice.

Leon Vogel
Top!
Working with KplusA was uncomplicated and pleasant. Our ideas were well received and professionally implemented. Even when faced with last-minute changes, the team was flexible and helpful. In the end, we had an all-around successful event – thankyou for that!

Leonard Gessner
We felt very well taken care of
We felt very well taken care of, there was frequent communication and the interpersonal relationships were great! We received regular updates and all our needs were addressed. As a result, we were able to rely 100% on the implementation. Their experience was also evident in the many helpful tips they gave us for asuccessful event. Many thanks to the whole team!

Liborio Manciavillano
A very good event agency!
Kevin and his team support us as an agency at various events and trade fairs. The team does an excellent job. Very good, structured planning. Spontaneous requests are dealt with quickly. We will gladly use them again. We are very satisfied.

Hans Schneider
Performance-oriented agency
The KplusA agency is highly committed and always thinks one step ahead. In addition, the employees are very reliable and always solution-oriented. The agency always strives to achieve the best results, and this is reflected in their work ethic and support.

Markus Rotter
Top!
Working with KplusA was uncomplicated and pleasant. Our ideas were well received and professionally implemented. Even when faced with last-minute changes, the team was flexible and helpful. In the end, we had an all-around successful event – thank you for that!

Leonard Gessner
Great consulting! Thank you!
Kevin's consultation was simply fantastic. In 60 minutes, he developed the perfect trade fair stand for us and gave us lots of tips on the topic (including a great concept for the next step). A clear case of over-delivering! Thank you very much!
Manuel Epli
We highly recommend this agency!
We highly recommend this agency. They presented us with great ideas right from the concept stage and quickly understood our structure and target audience. Everything went smoothly during the implementation phase, and we could always rely on Kevin and his team. Our interactions with the entire team were very pleasant. We will be booking the agency again for future events, including concept development! THANK YOU!

Agnes Heinze
Great project management and fantastic support!
Great project management and fantastic support! Although they didn't have much experience with golf tournaments, the KplusA team organized everything perfectly and, above all, kept track of all the details, even when things got dicey and time was of the essence. From planning to organization and, especially, project management, everything was fantastic. We had a top-notch event, thanks in large part to the help and support of Kevin, Lara, and Johanna from KplusA!

Michael Hill
We'll definitely work with KplusA again
We'll definitely work with KplusA again. The KplusA team is the perfect all-inclusive package for an event. Anyone who thinks they can organize a professional event where everything runs smoothly on their own is often mistaken. The KplusA team not only took care of the entire organization, but also helped us with all kinds of questions. What are the best practices in event marketing? How do we handle ticketing? Do we need speaker contracts? Which speakers are suitable for our target audience? Every question was answered within minutes via the WhatsApp group. A great experience that we will definitely repeat!

Marius Albrecht
Kevin and his team always give 100%
Kevin and his team always give 100% — reliably, competently, and with whole hearted dedication. That's how good teamwork produces excellent results. We'll stay connected with you!

Bettina
Top event thanks to Kevin and his team!
Top event thanks to Kevin and his team. We held a B2B event with almost 100 participants in Vienna. It was a specialist conference and the first event we had organized with the help of KplusA. The feedback from the participants was unanimously excellent, and everyone was surprised that this was our first event.

Gregor Weihs
Highly recommended
Kevin supported us with our “Agency Deep Dive” event. We had already organized several events before, but with the help of Kevin and his team, we were able to professionalize everything and take it to the next level. Their experience and expertise were evident in every detail!

Viet Pham Tuan
Kevin and his team are awesome
Kevin and his team are amazing! The stand at the real estate congress was such an eye-catcher that many people wanted to take a picture with us in front of it. It was definitely Instagram-worthy. Overall, the process was totally uncomplicated which allowed us to focus on our speech in advance. Everything was taken care of, from the concept to the creation of marketing materials. Never again an event without Kevin! If you want to focus on the really important things at an event, you should work with Kevin! It couldn't be more stress-free! When your exhibition stand becomes an eye-catcher, you don't even have to do any sales pitching anymore! People are simply drawn to it as if by magic. Thank you so much!

Dr. Verena Siegler
Never again without KplusA
The team proactively comes up with ideas that are worth their weight in gold. It's amazing that you can organize a professional event (or have it organized) without having to spend any of your own budget. After a briefing workshop, the team takes care of virtually everything. We'd do it again anytime. And never again without KplusA!

Kevin Be
Trust, reliability
Clear communication, respectful cooperation, reliable, trustworthy – I would gladly work with them again!

Alexander Wrobel
Competent & solution-oriented team
Competent and solution-oriented team! I hired Kevin to plan my mastermind and develop a concept. What impressed me was that he provided lots of great ideas that maximized the experience for the participants on site. Thanks to the whole KplusA team. Best of luck in the future! 👍🏻

Elias Kaltenberger
Perfect planning for an exclusive car dealers' event!
During our consultation, Kevin impressively demonstrated how we could design an event specifically for car dealership owners. His expertise, creativity, and precise planning gave me the confidence that we could put together an event that would offer car dealers tremendous added value. The cost-efficient implementation and Kevin's focus on every detail allowed me to relax and look forward to the event. Excellent consulting!

Robert Wiersbinski
Our experience with K+A was...
Our experience with K+A was consistently positive, which is why we would recommend this company without reservation. The team, led by Kevin Arenja, impressed us with their professional expertise, reliability, and exceptional creativity. Throughout the entire process, from the initial consultation to the final implementation of our projects, we felt we were in excellent hands. Particularly noteworthy is the seamless integration of all phases – from conception to realization. We are thrilled with the quality of the work and look forward to continuing our collaboration with K+A.

Sawan-Kumar
Super reliable partner
I have worked with Kevin from KplusA on several occasions. In June, I booked KplusA directly and I am more than impressed with their performance, friendliness, professionalism, reliability, communication, and initiative – to name just a few. I look forward to working with KplusA again in the future, and I am delighted with the extremely professional and pleasant collaboration.

Sebastian Maier-Hallard
Kevin and his team helped us out shortly before...
Kevin and his team helped us out shortly before an event that had already been planned. At first, I was very unsure whether the deadlines could be met, but they delivered. 😄 And faster and better than expected, too. Even last-minute feedback from us was implemented immediately. Thank you for a successful event!

Georg Borgert
Absolute Champions League...
Absolute Champions League working with Kevin Arenja and the entire KplusA team! Top ideas! Super-fast implementation! Utmost satisfaction! I can wholeheartedly recommend them to everyone!

Erik Kaatz
Planning and marketing 100% thought through
Right from the start, it's clear that Kevin and his team can cover everything related to events and, above all, that they understand and live their role as service providers 100%. This means thinking independently, making recommendations, warning of pitfalls, etc. – all of which is very reassuring for me as an event organizer. We already have in-house experience with purely organizational aspects from our own events. However, marketing is a topic in itself and so diverse that Kevin and his team really are the best for the job!
