ABOUT KORINT

----------------

 TLDR;

We are creating a next-generation Core Insurance Platform, designed to empower insurers & brokers to rapidly deploy innovative products, significantly reducing time-to-market and operational costs. Think of it as the “Shopify for Insurance”, enabling a new era of agility in the insurance industry.

We raised a 5m€ seed round in Sept. 2024 with Ventech, following a 2m€ pre-seed in Nov. 2022 with 360Capital. We are thriving and hiring across engineering roles.

 Our vision

Insurance plays a vital role in our society, enabling people to pursue their goals without fear of the unexpected. At Korint, we’re removing the technological barriers that prevent insurers from offering the best possible products to their customers—because we believe in a world where everyone can move forward with confidence.

 Our Product

We are building a new generation of Core Insurance Platform, designed for the rapid launch of insurance products.

Core Insurance Platform ? The software used to create, operate and modify insurance policies. So highly technical and very important - basically you cannot innovate in insurance without a high quality Core Insurance Platform.

You can have all the chatbots, mobile apps, AI models and fancy stuff but it is all useless if your core platform is legacy !

 Our Team

Our founders Jean-Baptiste (CEO) and Martin (CTO) are {Insurance + Tech} experts who have created several ventures already and have worked together in the past.

We are team of 20, with a structure that ensures everyone has a voice. We believe in continuous learning, and as we grow, so will your opportunities to take on new challenges and responsibilities.

 Our Values

Ambition: we aim big, because otherwise, where is the fun?
Progress: we care more about the grit, the steep learning curve, the resilience and creativity muscles, than the current status or where you come from. We  lean.
Bias for action: we make decisions and act quickly even in the face of uncertainty, and are willing to make mistakes in the process. We know that most decisions are “two-way doors.”
If you want to go fast, go alone. If you want to go far, go together: We're ambitious and aim high. To achieve our goals, team spirit and communication are essential.
Transparency: We're proud that 100% of our internal notes are public and over 80% of our Slack messages are in public channels. This is game changer for internal AI agents.
