Qui sont-ils ?


Kooalys is an InsurTech startup that offers 100% digital B2B car insurance and rewards companies that reduce their CO2 emissions.


We are currently witnessing two major trends on the mobility and transportation market:

  • A strong pressure to make mobility more sustainable, via lower CO2 emissions and less cars on the road.
  • The rise of on-demand mobility platforms (Uber, Velib, Lime…) that offer customers the same benefits of having a car but without the need to own one.

As a result, mobility is expected to shift from traditional, private ownership of cars (1 or 2 cars per family) to shared mobility fleets available on demand. By 2030, 50% of the distance travelled with cars will be via car sharing fleets.

This creates a unique opportunity for us to disrupt the market and create a green, tech and data focused Fleet InsurTech player. This is what Kooalys is about.


We are a new venture within the Admiral Pioneer incubator and are fully funded by the Admiral Group, the £8Bn-valuation UK and EU insurer. We have already raised €1.2m from Admiral.

Our goal is to become the market leader in Fleet insurance and management services. This market is already substantial (€2Bn in France in 2020, 10% of the total Motor insurance market) and is growing fast.

However, we want to be more than just insurers. We want to use our tech and data to help our customers make the move to sustainable mobility. This involves notably the launch of a “green driving app” that rewards our customers for lowering their CO2 emissions while driving.


  • A digital native, green, smart, innovative product that gives total control and transparency to the final customer in order to reduce CO2 emissions.
  • A state-of-the-art data and tech stack – insurance is about using data to predict risk, and we want the best data model as the foundation of our business.
  • A great team - we are looking for talented, curious, ambitious and inclusive individuals to create a venture unlike anything in the insurance market.

💡 Tech is the core asset at Kooalys. People want simple, cheap and clear services from their insurance. Our goal in the team is to create the tech that will allow our users to have all of these services.


  • Learning a lot.
  • Working on complex yet very interesting topics.
  • Deeply improving an industry that needs technology to get better.
  • Growing as we grow. And we expect to grow a lot.

🤩 Advantages

  • Very competitive remuneration package on offer for the Parisian market
  • Super health insurance and holiday policy
  • WFH up to 2 days per week

We are located at WeWork rue Lafayette (9th) in the heart of Paris.
