At its best, parametric insurance delivers clarity when volatility strikes. But scaling that promise takes more than models: it takes real claims data, market feedback and the ability to solve for both reinsurers’ confidence and cedents’ earnings risk.

In this episode, Matthew Grant speaks with Matt Coleman, Chief Risk Officer at The Demex Group, a reinsurance MGA using a new modelled loss index to reshape how the market covers severe convective storms, one of the fastest-growing sources of weather-driven loss.

Our conversation picks up where our previous webinar left off, and explores how Demex has grown distribution, secured broker support and validated its approach in a live risk environment.

In this conversation Matt touches on:

Why 2025 has already seen above-average tornado, wind and hail activity and how recoveries are already flowing
How Demex’s RCR Re cover mimics indemnity but pays out on a modelled index
Why omitting sensors and relying on robust weather and claims data reduces basis risk
The advantages of training models on cedents’ actual ground-up claims, not diluted industry averages
What reinsurers want in secondary peril covers and how Demex packages risk to match that appetite
Why broker engagement has been critical to growth, and what their clients are asking for
What it means to build in response to a genuine market problem not just to push a technology

Along the way, Matthew and Matt talk about why carriers are willing to share granular claims data when the product is strong enough and why early validation matters in parametric.
