Six start-ups presented their ideas – ranging from e-commerce to agriculture – to a panel of experts and the audience at the TU Start-up Award 2025. For their pitches, the three best-ranked founders of the start-up companies PartikelART, Grwm. and Rivopump were awarded prize money totaling €14,000, which was sponsored by the Wilo Foundation. The annual start-up prize is conferred by the Center for Entrepreneurship and Transfer (CET) on successful start-ups affiliated with TU Dortmund University.

First place, worth €6,000 in prize money, was won by PartikelART. The team led by managing directors Dr. Ronny Zwinkau and Roman Möhle from the Institute of Production Systems (IPS) at the Department of Mechanical Engineering has developed a mobile particle analysis system that assesses the cleanliness of production processes. The start-up offers companies digital solutions for monitoring the contamination of critical components and resources. The team’s pitch convinced not only the expert jury but also TU capital, the venture capital seed fund of TU Dortmund University, which awarded PartikelART this year’s special prize.

The social fashion app Grwm. won second place and €4,000 in prize money. GRWM is the acronym for “Get ready with me”, a popular social media trend where content creators show their followers how they apply their make-up or choose their outfits. This is precisely where the app comes in, which aims to create a seamless interface between creators, brands and shopping by linking outfits displayed on social media directly to where users can buy them and by offering a personalized, AI-curated fashion feed. The start-up’s founders, Ben Richter, Niklas Toporysek and Tom Zulbeck, participated in CET start-up programs with their business idea. For its convincing concept, the team won second place and the audience award worth €1,000.

The third prize, to the value of €3,000, went to the start-up Rivopump, which has developed a self-sufficient water pump based on a physical operating principle. The aim is to offer smallholders in sub-Saharan Africa a sustainable solution for irrigating their fields, which are threatened by drought. Unlike diesel pumps, the Rivopump is driven by hydropower and constructed from recycled materials. Anton Güntheke, a member of the Rivopump team, is currently studying for a Master’s degree in mechanical engineering at TU Dortmund University.

Other finalists were the start-ups PottPilz, Ziya and SemanticMap, which are developing sustainable construction materials as well as AI solutions for companies and market researchers.

Information and networking

The expert jury for the competition comprised the following members: Professor Tessa Flatten (Professor for Technology Management and Vice President International Affairs, TU Dortmund University), Dr. Thomas Seidensticker (CSO, Simplyfined), Dr. Martin Oettmeier (Global Director R&D Strategy, Innovation and Research & Predevelopment, Wilo Group), Hendrik Schabsky (CEO, ATLAS Safety Shoes) and Dr. Hans Schulze Schwienhorst (Managing Director, Jaeger Gruppe, and member of the Investors’ Advisory Board, TU capital). Dr. Thomas Seidensticker, who was part of the winning team in the previous year, encouraged all the start-ups in attendance to address challenges with passion and perseverance. In a keynote speech, Hendrik Schabsky reported on modernization in a family business and advised how young companies can create sustainable structures for long-term growth.

Alongside presentations and the pitch competition, the event additionally offered various opportunities to obtain further information on how to launch a start-up and to network: During the evening, 20 other start-ups were able to introduce themselves and discuss with guests. Companies and investors were also displayed on a kind of noticeboard called the “Partner Wall”. With potential collaboration in mind, QR codes helped the participants to connect with each other.
