About us

REINTRIEB GMBH is an Austrian-German start-up in Vienna for the development of profitable cleantech: profitable for the environment, for our customers and our investors. Put simply, this is the Reintrieb Investment Case. 

Our first product is a water-lubricated high-performance transmission. Instead of mineral oils that are harmful to the environment, the climate and our health, or so-called biological lubricating oils, we use naturally occurring salt or fresh water. For cooling and lubrication. Mind you, without any additives. Our technology is 100% sustainable in the sense of the UN Sustainable Development Goals. The technical development status of our two lead products is currently TRL 4 and TRL 5, respectively.

Our second product is an innovative marine propulsion system. Our goal: a quarter less draught with improved efficiency at the same time. This enables ships to navigate even in shallow waters, saving fuel and emitting less CO2. 

Our inventions are generally protected by comprehensive intellectual property rights.

To enter the market, Reintrieb is concentrating on one area: maritime propulsion systems. Our engineers bring decades of experience in this sector to our company. Numerous patents prove their innovative and out-of-the-box thinking. 

Our entry market is inland navigation on the Rhine-Main-Danube, Germany and Benelux with a market potential of over 12,000 ships. Overall, EU inland navigation is currently facing a phase of massive investment in environmental and climate protection. 

The reinvestment USP is a perfect fit: environmental investments that also generate profit. First LOI’s of potential customers are already available. As a result, we anticipate pull demand when the product is ready for the market.

Reintrieb is open to investors who invest in companies in order to achieve measurable, positive social or ecological improvements in addition to financial returns. Our self-image is that of an impact investment. Private investors from Austria, Germany, Liechtenstein and Great Britain are currently invested in Reintrieb.

Whom we bring benefits

Our pioneer clients

Reintrieb actively seeks dialogue with pioneering customers. As a sparring partner, you accompany us through the development process. And together we perfect the market-ready product; for your inland navigation needs. But not only that. We are also already interested in users who operate transmissions in underwater applications or in areas close to water who have a vital interest in eliminating the risk of contamination.

Our inventions make two things possible for inland navigation.
On the one hand, our side-by-side propulsion concept will improve efficiency. At the same time saving a good quarter of the draught - all depending on the operational profile. On the other hand, a water-lubricated transmission in your azimuth or bow thruster frees the shipowner from numerous problems as described above.

Do you also think our inventions make sense? Then take advantage of the opportunities it offers together with us. It is our goal to inspire customers to use a new and sustainable propulsion technology. The best way to achieve this is to work together. If you support us as a pioneer customer on the way to market maturity and series production, we will support you in return with attractive conditions. Both for new construction and for conversion of your propulsion system. We are also working together with financing partners to put together a package for financing and promotion for pioneer customers. And last but not least, pioneering customers also benefit from the accompanying communication measures that Reintrieb implements.

Would you like to find out more about our services for pioneering clients? Simply contact us directly. Right here and now.

Our customers

Our first product will be a water-lubricated high-performance transmission for underwater use in ship propulsion systems. The gears are simply lubricated with water instead of highly problematic mineral oil. On the one hand, this eliminates the environmentally harmful oil lubrication in watercraft. This means that the daily, worldwide seeping poisoning of our waters can finally be effectively prevented. Leakage of gear oils in the life cycle of transmissions used to be a problem that could practically never be completely prevented. Until now. By using water instead. On water as well as on land.

On the other hand, leakage of water into the transmission oil is the most frequent cause of gear damage or operational breakdowns on ships. Expensive oil changes and costly disposal of the contaminated oil-water emulsion are the result. Often even more expensive dock stays. The cost of seals, including meticulous maintenance, would be obsolete. The entire supply chain for the supply and disposal of toxic lubricating oil would equally be obsolete. Including all problematic side effects, as well as the disposal of the waste oil, which is usually simply carried out through climate-damaging combustion. At the same time, the considerable costs - and also the image risk - of any probable environmental contamination would have been effectively eliminated.

Our industrial partners

Reintrieb offers production partners from the manufacturing industry attractive licensing models. The common goal is the rapid achievement of strategic milestones. Especially with regard to sales and market position. Reintrieb brings the proof of concept, the license and specific know-how into a partnership. Our partner of choice has their good name and their proven industrial manufacturing potential. In addition to a business climate that is open to new ideas, an innovative atmosphere and flexibility, we attach great importance to the shortest possible decision-making paths. And also important: the acceptance of Reintrieb as an "ingredient brand". We would be happy to discuss the details of a possible cooperation in person.

If we haven't found you yet, please contact us. The best thing is right here and now.

Our investors

No, we're not looking for any new friends. Also no lifelong partnership until the end of the rainbow. But we all know that that’s where the pot of gold is. And we are looking for supportive and demanding investors who want to find this pot of gold together with us. To walk this part of the way together.

Especially those who are already subscribed to the principle of sustainability. Or even better, those who have already gained experience in this field. Because we at Reintrieb want to achieve our economic, ecological and social goals guided by ESG criteria. For this, we are looking for allies.

A typical Austrian saying and success principle is: "Talking brings people close". Of course we have pitch decks, term sheets and a concise business plan summary. An encyclopedic long version is also available for you if you feel like a deep dive. But in our opinion, all this doesn’t show the complete picture.

Reintrieb offers various investors tailor-made forms of investment. Whether you are a private investor, a business angel, a VC or a strategic investor, getting to know us personally is always a prerequisite. This gives you the opportunity to find out how you rate our ideas and plans and, most importantly, how you rate us as a team. And whether we match your ideas. And vice versa.

No, we will not be angry with you if you prefer not to invest afterwards. But please don't be angry with us either if we say no the other way round. Ultimately, the chemistry must be right. You certainly agree that we both should get the mutual feeling that we can rely on each other. Ideally before we leave the base camp for the summit.

So please, do not start by asking what kind of valuation we employ. In our world, the size of the investment determines the valuation. Not the other way around. We prefer to discuss business plans, milestones and monetization with you. And what we can do for each other in the future. Once we find a common denominator on these topics, we will also find it in the investment size.

We look forward to good conversations with you.

Our environment and our fellow human beings

Reintrieb develops innovative, environmentally-friendly high-performance transmissions. Production is carried out through our industrial partners. We are ready to explore a still largely unknown new continent in the world of tribology: water lubrication. Our approach is technically highly sophisticated. But above all, it is 100% sustainable.

The threat of climate change presents us with the challenge of realigning our economy along financial and non-financial indicators. This is exactly what Reintrieb does. Our approach impacts five-fold on the UN Sustainable Development Goals. In concrete terms, this concerns the following goals:

SDG 6 "Clean Water and Sanitation
SDG 9 "Industry, Innovation and Infrastructure"
SDG 12 "Responsible Consumption and Production"
SDG 13 "Climate Action"
SDG 14 "Life below Water".

Reintrieb activities are based on the ESG management principles. This is the abbreviation for "Environmental, Social and Governance". It is an established term from the world of finance. It expresses whether and how we consider and evaluate ecological and social aspects as well as the type of corporate management in our entrepreneurial decisions in everyday life or when calculating future scenarios. Reintrieb cooperates with esg-cockpit.com for this purpose.

Our employees

As a start-up for highly innovate – even disruptive – products, we are always looking for new talent. If you are a young, dynamic multi-elite university graduate, with a sustainable attitude to life and an unconditional willingness to take up the fight against climate change, at least 20 years of professional experience in transmission and ship propulsion engineering and looking for an internship … Of course.

Just kidding. We are more than willing to forego young and dynamic in favor of experienced and target-oriented. Young is not an obstacle. Older even less. Either way, we need technical staff who love to contribute their own ideas. And to implement them. People who love to tinker and try. Combining creativity with technical skills. Flexible lateral thinkers. Diversity is our trump card.

We don't lock away creative ideas to sing sadly in the prison choir. We play Nutcracker Suite instead of Nabucco. We want engineers with great passion for really hard nuts. Character heads who express "crazy" thoughts are not only expressly desired, but thinking out-of-the-box is a cardinal virtue with us.

And we are willing to give for that. As a start-up, this means: flexible working time models. And a share in our joint success in the form of interesting sweat equity models. Would you like to find out more about us? No problem. You are only a small click away from our 200% discreet HR professional.

Stay up-to-date!
