Exponential Risk is InsTech’s monthly newsletter dedicated to modelling, climate driven risk and near term forecasting insurance news.
London calling, models evolving
The Brief
It’s been an active few weeks across the Exponential Risk community.
On Tuesday evening, we hosted Fathom, Reask and Maximum Information to discuss how multi-model strategies are improving understanding of individual risks. The discussion reflected a shift across the market: from reliance on single-model views to integrated, comparative approaches that better capture uncertainty and opportunity. Thank you to everyone who joined us for the debate and networking.
This week also marks a major milestone – the launch of the Exponential Risk London 26 brochure.
Building on the success of last year’s sold-out conference, we’re expanding to a larger venue with 500+ attendees. Expect more opportunities to learn, connect and collaborate – with new networking areas, expanded breakouts and an enlarged exhibition floor. The brochure includes full details on this year’s themes, advisors and the return of the London Catastrophe Modelling Awards.
In two weeks, we’ll be hosting ZestyAI for our next networking event, exploring how AI is being applied to one of the most volatile and costly risks in U.S. property insurance – wildfire. We’ll examine how AI and property-level data are reshaping how insurers assess wildfire exposure and build portfolio resilience.
Plenty more to come this autumn, but for now, start by downloading the Exponential Risk London 26 brochure and saving the date for 10-11th March, 2026.
