How a successful carpooling project works
Assess commuting flows
We map commuting patterns, shift times and site accessibility to define the right roll out scope and success targets.

Track, optimise & scale
Live KPIs and reportings show adoption and impact and help optimize incentives and activations to scale what works.
Companies in our region were struggling to recruit because of mobility issues. Today, we have a solution to offer them, especially since Karos takes care of promoting the service directly within companies.

Carpooling combines financial relief with climate action: by creating our own carpooling service in the Frontonnais, we enable residents to achieve significant savings while reducing their carbon footprint.

President of the Communauté de communes du Frontonnais
People can choose how they travel rather than having their journeys dictated by circumstance. At the same time, carpooling provides mobility in areas where a bus service would not be efficient.

Our ambition is simple: to offer people working in our region a practical, affordable and environmentally friendly way to get to work. A resident commuting every day from Saint-Rémy-de-Provence to Avignon who chooses to carpool as a passenger can save around €1,300 per year on fuel alone. The benefits are very tangible: lower costs for residents, fewer cars on our roads and greater solidarity across our region.
Romain Thomas
President of the Communauté de communes Vallée des Baux-Alpilles
In some parts of our region, expanding the bus network is relatively straightforward. At the same time, other areas are very rural and sparsely populated. There, Karos complements the existing bus network.
Jérôme Dubois
Vice-President of Durance-Luberon-Verdon Agglomération
Transport connectivity at the GENDORF Chemical Park has long been an important issue for our site. With Karos (formerly goFLUX), we were able to create an accessible and flexible mobility solution for everyone working at the chemical park. We see the app as a valuable complement to public transport: it is even more flexible than a bus route, as colleagues travel the same commuting routes at many different times. That is why we can also recommend the solution to other companies in the region.
Alfred Sandner
Project Manager, InfraServ Gendorf
Our main goal was to give employees and apprentices from rural areas a reliable way to reach the chemical park. At the same time, we learned that a good mobility offer alone is not enough: personal engagement, on-site activations and continuous communication with employees are key.
Michaela Dufter
InfraServ Gendorf
For us, it is essential to future-proof our site while ensuring that all employees are part of the journey. The carpooling solution combines sustainability with tangible benefits for our employees: it helps ease parking pressure while fostering interaction and stronger connections across the workforce.
Andra Seidler
Transformation Manager at Siemens Switchgear Plant Frankfurt
One of the most important insights for us is that incentives significantly ease entry: they motivate people to try the app and actively connect with each other. This is crucial because without active usage there is no community – and without a community, new users cannot find a network to join. At the same time, we see a clear behavioural change: people who previously travelled alone are now more often forming car‑pooling groups because the app makes ride‑sharing easier and more attractive.

Most of the kilometres we travel are for commuting, and the transport mode with the highest person‑kilometres in Germany is – the unused car seat. [...] We need complementary building blocks for the transformation of the transport sector: a functioning public transport system for short and long distances, physically separated bike lanes, and, yes, also the car – preferably fully occupied. And those who, on this path, also engage in conversation with their neighbours contribute not only to the mobile and energy transition but to something greater: a liveable future in a good neighbourhood.

Die App ist lediglich ein Werkzeug, um aus individueller Mobilität gemeinschaftlich organisierte Mobilität zu machen. Die Ergebnisse zeigen: Es funktioniert! Was als Pilotprojekt [im Ilm-Kreis] begonnen hat, ist innerhalb kurzer Zeit zu einem funktionierenden Mobilitätsangebot geworden. [...] Mobilität ist nicht ausschließlich Aufgabe von Staat, Verkehrsverbünden und Infrastrukturbetreibern. Mobilität entsteht auch dort, wo Unternehmen Verantwortung für die Wege ihrer Beschäftigten übernehmen und gemeinsam mit Kommunen praktikable Lösungen entwickeln.

With Karos [ehem. goFLUX], we have a partner that provides an innovative component […] and continues to develop it together with us. Karos is far more than a service provider: it acts as a problem solver, thought partner and trusted advisor.

We are delighted to see SWB-Mitfahren delivering such strong results. What began in Bonn as an innovative partnership is becoming a model for cities and employers across Germany. In areas where buses and trains do not operate, or outside regular service hours, it is essential to offer people a flexible mobility option while reducing car traffic at the same time. Carpooling can make an important contribution to cutting CO₂ emissions.

Many of our long-serving employees commute up to 70 kilometres to N3 Engine Overhaul Services. It was important to us to support our team in this area. Carpooling helps reduce fuel costs and makes us a more attractive and accessible employer for new colleagues who do not have a suitable public transport connection.

Frequently asked questions
Answers to the most important questions regarding implementation, cost structure, data protection and impact.
Does carpooling work for industrial zones with several employers?
Karos works well for industrial zones and business parks where several employers share the same area. By pooling commuters across companies, the network reaches the critical mass needed for reliable matching, even when a single company alone would have too few participants.
Can Karos support our CSR and sustainability reporting?
Yes. Carpooling contributes directly to lowering commute-related emissions, which can feed into your CSR and ESG reporting. Karos provides data on shared rides and estimated CO2 savings so you can document the environmental impact of your mobility initiatives.
How can Karos help our company with employee commuting?
Karos helps companies reduce home-to-work commuting challenges by connecting employees who live and travel along similar routes. This eases parking pressure, lowers commuting costs for staff and supports your corporate sustainability goals, especially for sites in areas with limited public transport.
How can we encourage our employees to start carpooling?
Employers can encourage participation by communicating the service internally, offering incentives, and integrating it into their broader mobility policy. Karos supports you with a communication toolkit and guidance to help drive adoption among employees.
Can carpooling help reduce parking pressure at our site?
Carpooling reduces the number of single-occupancy cars travelling to your site, which lowers demand for parking spaces and the associated costs. It is often a faster and cheaper solution than building new parking capacity.
