Our business model

Founded in 2019, Seyna is an ACPR-licensed insurer

Our business model is unique: we carry the risk and delegate distribution and management to those who know their clients best: brokers.

Every insurance product is tailor-made, white-label and continuously optimised

Led by technology

We have been building a leading technology-driven insurer for brokers who want to launch, diversify and grow their offerings across Europe.
‍
Our ambition: to become the market’s efficiency standard for brokers, through a model of complete delegation

The most efficient insurer

How do we deliver this value to brokers? It rests on two foundations:
‍
Our technology, built around AI, lets us automatically transform and integrate broker data, detect and correct data errors within hours, analyse portfolio performance in real time, and automatically generate brokers’ accounting statements;

‍A team of experts, equipped with our technology, supporting every broker from a product’s launch through to the monitoring of its performance. It makes our experts highly responsive: pricing, legal documentation, cover adjustments or steering-committee preparation are handled within days.
