About us

Kplusa:
The event agency from Düsseldorf

As a specialized service provider, our agency combines experts in conception, event strategy, event marketing and event management. In recent years, we have worked for many large customers such as Transfermarkt, personal brands such as ex-CEO Dr. Michael Stoermer and software companies such as LeadTable.

Our story, our founder, our mission

Founding history

Kevin Arenja founded KplusA in 2021 with the first projects. The goal was to make events more strategic, emotional and measurable. Important customer projects followed in 2022, such as the anniversary for di-soric, and partnerships with agencies as subcontractors. In 2023, the team grew to six people. With over 50 events a year and a focus on conception, consulting and event management, our reputation as agency with strong implementation skills was established. In 2024, there were already over 60 projects, and in 2025 we were working with DAX companies, market leaders such as Transfermarkt and the BVFI (Federal Association for the Real Estate Industry). Today we count around 70 projects per year, we are a training company and a strategic event partner for leading companies.

About founder Kevin Arenja

Kevin Arenja is the founder and managing director of KplusA Communications. As TÜV-certified expert in sales psychology, lecturer in event management at THM Technische Hochschule Mittelhessen and IHK examiner, he has deep expert knowledge and over 12 years of industry experience — from strategic roadshows and sales events to international events with up to 3,500 guests. After a B.A. in Media and Event Management, an MBA in Business Administration and his Apprenticeship as an event manager, Kevin implemented well over 320 projects for corporations, medium-sized companies and hidden champions. His mission: making events measurably successful — with emotional relevance, clear strategy and an eye for what really works.

About KplusA

Behind KplusA stands an experienced team, which not only organizes events, but rather lives them. We turn events into real experiences — with personal commitment, engagement and with an eye for the essential aspects.

We know how much trust it takes to hand over an event. That is why we work with transparent processes, permanent contact persons and real responsibility. And when it comes down to it, we are there, by your side, on site.

Our advantage: the combination of marketing experience, digital efficiency and directing expertise. As a TÜV-certified agency, we bring structure to complex processes and ensure a smooth implementation so you can focus on your guests and content.

That is what defines us

We believe in experiences that move the participants, not just for the moment,
but with a lasting effect on people's minds and hearts. Because we tackle events holistically — from the initial strategy to the last goosebump moment.

Strategic thinking meets creative instinct

We combine event know-how with marketing expertise. The result is a well-thought-out concept that not only works but also promotes your brand in a goal-oriented manner.

Hands-on mentality instead of hot air

We keep our promises. An experienced team that thinks of everything, assumes responsibility and is there for you from start to finish.

Experience you can rely on

For over 10 years, we have successfully supported medium-sized companies with events of all sizes: regionally, nationally, internationally. More than 320 events speak for themselves.

TÜV-certified sales psychology

As the first TÜV-certified agency, we deliberately design events psychologically – for the right marketing strategy, low no-show rates and full halls.

Reliability & Trust

Clear agreements, honest communication and transparent budgets — for you, this means planning dependability without unpleasant surprises.

Digital planning & smooth direction

Through digital planning tools, automated processes and professional process management on site, we ensure efficiency, structure and an event that is both technically and personally convincing.

Our awards

Maximum expertise for your event

TÜV-certified event agency

We are the first event agency in Germany to use TÜV-certified sales psychology specifically targeted towards the event context. Why? Because successful events are not product of chance — they follow a well-thought-out concept. With in-depth knowledge of psychological customer communication, we develop event concepts that work: more participants, higher conversion, stronger customer loyalty. Whether it's a launch event, a conference or an internal kick-off — our concepts specifically address the emotions of the target group and make your message memorable. The TÜV seal stands for tested methods and genuine quality of results.

“fairpflichtet” sustainability

As an official signatory of the Sustainability Code “fairpflichtet”, we at KplusA choose responsibility instead of greenwashing. For us, sustainability is not a buzzword, but a daily common practice: We deliberately plan CO₂-conscious logistical routes, we favor local partners and service providers, we rely on digital processes instead of piles of paper and we develop resource-efficient event concepts. This is how we create events that not only impress but are also sustainable.

TOP employer

As an event agency with high standards in respect to precision, speed and creativity we know that only those who are strong internally can achieve great things externally. That is why we at KplusA not only promote talent, but also health and wellbeing. Our award as “sustainably healthy employer” stands for a work environment that consists of mental strength, physical health and real opportunities for development — from flexible working to continuous training opportunities. Because a strong team is the basis for strong events.

IHK training company

We take responsibility — not only for our customer projects, but also for the future of our industry. As certified IHK training company we actively train event managers and invest in the next generation of event professionals.

Social commitment

As an official Johanniter's “Partner in Project” we are committed to social responsibility beyond day-to-day business. Wir support social projects like the Benrather Tüte, which provides food to disadvantaged people in the Düsseldorf area — through donations, campaigns and media attention. It's clear to us that effective events not only create connections between brands and people, but also between business and society.

Excellent customer satisfaction

We are proud of real results and of the feedback from our customers. About 32 five-star reviews on Trustpilot speak for themselves — and still rising. From SMEs to corporations and start-ups: Our customers particularly appreciate our speed, our reliability and tangible passion, with which we approach every project.
