Really excellent work

I've already had very bad experiences with event agencies, but I have to say that Kevin has done a great job. We have been able to sharpen our vision and positioning so enormously after just one workshop... We are now working together on several major projects and KplusA accompanies 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 was very targeted and picked me up from second 1. “They understand me here!” was my first thought. The implementation of the homepage, the branding and the templates for social media completely convinced me. It is a pleasure for me to go out in public with the result because it simply looks great, appeals to me, represents and sells me! Kevin and Johanna made it easy for me right from the start and so I had exactly the support I needed. Many helpful tips and food for thought helped me with planning and implementation or simply strengthened my back.The goal for the organization next year: to work even more with KPlusA. 💪

Events on another level

As a service provider, I regularly attend KPlusA events — and each time I am impressed anew. The professionalism with which they work here is really impressive. I've already seen many events, both with and without KplusA — and to be honest: The difference is huge. Whether it's the process, the look & feel or the atmosphere among the participants — everything just fits at KplusA. For me as a videographer and photographer, this is worth its weight in gold because I can capture the best emotions exactly when everything is running smoothly and people are in good spirits. And that is the standard at KplusA. The team is also super organized, reliable, professional — you just notice that everyone here knows what they're doing. Unfortunately, you don't often experience such reliability anymore. Kevin Arenja is someone who thinks along. Fair in advice, extremely forward-looking and with a great sense for various industries. For me, it's clear: If you want to set up a really successful event, KPlusa is the right place for you.

We were picked up super

We were picked up very well, the communication is regular and great interpersonal! There were regular updates and all needs were addressed. As a result, we were able to rely 100% on the implementation. You can also feel the experience with many helpful tips for a successful event. Thanks to the whole team!

A very good event agency!

Kevin and his team support us as an agency at various events, events and trade fairs. The team is doing an excellent job. Very good, structured planning. Spontaneous concerns are addressed quickly. I would love to do it again and again. We're very happy.

Strong advice! Thank you!

Kevin's advice was simply strong. In 60 minutes, he developed a perfect exhibition stand for us and gave lots of tips on the topic (including a great concept for the next step). Clear over-delivering! Thank you so much!

We can only recommend this agency!

We can only recommend this agency. Great ideas were presented to us right from the concept stage, and we quickly understood our structure and target group. Everything also went smoothly during implementation and we could rely on Kevin and his team. The whole team was also very pleasant to deal with. We will also book the agency for further events including a concept! THANKS!

Great project management and great help!

Great project management and great help! Although there wasn't much experience with golf veneers, the team from KplusA organized everything brilliantly and in particular kept track of everything, even when things got dicey and time-critical. From planning to organization and especially project management was great. We had a great event, also thanks to the help and support of Kevin, Lara and Johanna from KplusA!

Anytime again with KplusA

Anytime again with KplusA; 'The team from KplusA is the perfect all-round carefree package for an event. Anyone who thinks that they can organise a professional event on their own, where everything runs smoothly, is often wrong. The KPlusA team not only took care of the entire organization for us, but also helped us with all sorts of questions. What are best practices in event marketing? How do we handle ticketing? Do we need speaker contracts? Which speakers are suitable for our target group? With every question, we were helped within a few minutes via the WhatsApp group. Top experience and always again!

Top event thanks to Kevin and his team!

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

Kevin supported us for our “Agency Deep Dive” event. We had hosted several events before and with the support of Kevin and his team, we were able to professionalize everything and take it to the next level. The experience and expertise in particular have been noticed in the details!

Champions League!

Kevin and his team are Champions League when it comes to organizing events and masterminds. I've hired him to organize my mastermind trips around the world. The trip to Madeira made such waves that I was overwhelmed with recommendations from every participant and asked people enthusiastically whether they could be there next time. It's definitely worth hiring Kevin!

Kevin and his team are awesome

Kevin and his team are awesome! The stand at the Immokongress was such an eye-catcher that many wanted to take a picture with us in front of it. The exhibition stand was therefore absolutely suitable for Instagram. In general, the process was completely uncomplicated and we were able to concentrate on our speech in advance. From concept to marketing material creation, everything was taken care of for us. 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! If your exhibition stand is an eye-catcher, you don't have to make any more acquisitions! People are simply magically attracted. Thank you so much!

Never again without KplusA

The team proactively comes up with ideas that are worth their weight in gold. It's amazing that you can set up a professional event (or have it set up) - without having to spend a budget yourself. After a briefing workshop, the team works on almost everything. Anytime again, and never again without a clue!

Unsere Erfahrungen mit K+A waren durchweg positiv, weshalb wir dieses Unternehmen ohne Vorbehalte weiterempfehlen möchten. Das Team, angeführt von Kevin Arenja, hat uns mit seiner fachlichen Kompetenz, Zuverlässigkeit und außergewöhnlichen Kreativität beeindruckt. Während des gesamten Prozesses, von der ersten Beratung bis zur finalen Umsetzung unserer Projekte, fühlten wir uns hervorragend betreut. Besonders hervorzuheben ist die nahtlose Integration aller Phasen – von der Konzeption bis zur Realisierung. Wir sind begeistert von der Qualität der Arbeit und freuen uns auf die Fortsetzung unserer Zusammenarbeit mit K+A.

Super verlässlicher Partner

Ich habe mit Kevin von KplusA mehrfach zusammengearbeitet. Im Juni habe ich KplusA direkt gebucht und bin mehr als überzeugt von Leistung, Freundlichkeit, Professionalität, Zuverlässigkeit, Ansprache, Initiative - um nur ein paar zu nennen. Ich werde auch künftig mit KplusA mit Freude zusammenarbeiten und freue mich über die äußerst professionelle und angenehme Zusammenarbeit.

Planung und Vermarktung 100% mitgedacht

Man merkt von Anfang an, dass Kevin und sein Team alles rund um das Thema Event abdecken können und vor allem ihre Rolle als Dienstleister zu 100 % verstehen und leben. Das bedeutet: eigenständig mitdenken, Empfehlungen aussprechen, vor Fallstricken warnen etc. – das gibt mir als Veranstalter ein sehr gutes Gefühl.Durch eigene Events haben wir intern bereits Erfahrung mit der reinen Organisation. Die Vermarktung ist jedoch ein Thema für sich und so vielfältig, dass man damit bei Kevin und seinem Team sehr gut aufgehoben ist!
