About Reintrieb
REINTRIEB GmbH is an Austrian early-stage technology company based in Vienna. The company develops patentable mobility cleantech solutions for decarbonization: a water-lubricated high-performance gearbox that is cooled and lubricated with natural water without mineral or biological lubricating oils, as well as a marine side-by-side propulsion system that saves around one quarter of draft while also improving efficiency. Reintrieb does not manufacture itself; the products are exclusively intellectual property that is licensed by sector or geography. Together with pioneering customers and industrial development partners, the applications are developed to production readiness, supported by funding acquisition assistance and accompanied by communication measures. The technical development status of the two flagship products is TRL 4 and TRL 5. The entry market is European inland waterway transport with more than 15,000 vessels, with a focus on Rhine-Main-Danube, Germany and the Benelux countries; in addition, industrial applications such as pumps, production machinery and gearboxes for e-mobility are being opened up.
