Reiner Prohaska
Founder, CEO & Majority
Shareholder of Smart United

I founded Smart United with a clear conviction: technology carries responsibility. It must protect people — not just optimize processes.

For more than two decades, I have been building and scaling technology-driven companies. My background is rooted in software and system architecture, process design, and the development of high-performance organizations. I do not believe in speed at any cost. I believe in precisely engineered solutions that work sustainably — technically, economically, and socially.

At Smart United, we pursue a clear vision:
to make indoor environments so safe that infection risks are drastically reduced — permanently, measurably, and without limiting human interaction.
Our UV-C technology is developed in close collaboration with leading scientists and engineers and meets the highest standards of effectiveness, safety, and scalability. We do not think in individual devices, but in holistic systems that protect entire rooms and buildings.

As CEO, my role is to reduce complexity, make clear decisions, and create an environment where exceptional people can perform at their best. Our culture is built on integrity, responsibility, scientific rigor, and the commitment to doing things right — not just fast.

Smart United is not a short-term project.
We are building a technology platform with global relevance — one that protects health and sets new standards. Our ambition is to make a real, measurable impact for organizations, institutions, and, most importantly, for the people who occupy these spaces every day.

Founder and CEO of
Sunny Cars & Majority
Shareholder of Smart United

I have built a company with Sunny Cars over many years that stands for reliability, clear customer orientation, and an absolute focus on quality. This attitude also guides my approach to new entrepreneurial ventures: I am interested in solutions that have an immediate effect, are permanently relevant, and reliable for end consumers.

What convinced me at Smart United is the commitment to translate scientifically based technology into a concrete benefit – namely to ensure health indoors while at the same time reducing the risk of infection. What matters to me is not the idea alone, but its effectiveness in everyday life.

The work of Reiner Prohaska and his team combines exactly that: technological substance, high quality standards, and a clear understanding of how health protection can be concretely improved. For me, this combination is the foundation of any sustainable development.

I accompany Smart United with entrepreneurial experience and a strategic perspective. What is crucial for me is that innovation does not remain abstract, but works reliably in everyday life and makes a real contribution for people.
