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!

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.

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.💪

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.

Great consulting! Thank you!

We highly recommend this agency. They presented us with great ideas right from the concept stage and quickly understood our structure and target audience.

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!

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!

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.

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!

Never again without KplusA

The team proactively comes up with ideas that are worth their weight in gold.

We'd do it again anytime. And never again without KplusA!

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.

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.

I have worked with Kevin from KplusA on several occasions.

Kevin and his team helped us out shortly before an event that had already been planned.

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!
