Jeff Radke, Co-founder & CEO: Accelerant: Industry growth spurts: the influence of risk exchange platforms in specialty insurance (348)

26 minutes

What does it take to fundamentally rethink how specialty insurance is traded, structured and scaled?

In this episode, Robin Merttens is joined by Jeff Radke, co-founder and CEO of Accelerant, for a deep dive into the mechanics of a rapidly growing risk exchange that’s quietly reshaping the MGA and MGU landscape. It has been three years since Jeff joined us on the InsTech podcast, and even Accelerant has radically evolved as a business.

This isn’t, however, just another technology story. Jeff shares frank insights on building trust in a data-driven ecosystem, how Accelerant has used AI to make tangible portfolio improvements and why he believes platform-based risk trading will become the dominant model for specialty lines. Unlike many other discussions about AI in insurance, this episode focuses on what’s already working – from subrogation improvements to portfolio optimisation.

There’s also a broader message here: about stepping back to see how much the market has changed and why the next evolution may already be underway…

Key Talking Points

The value of long-term partnerships – why Accelerant provides five-year capacity commitments and expects transparency in return

Applying AI where it matters – reducing loss ratios and boosting subrogation with machine learning and large language models

Cost leadership in a softening market – why expense ratio advantage trumps rate cycles in SME and specialty risks

Looking ahead – how AI is reshaping roles, workflows and the entire insurance value chain

The rise of risk exchanges – why specialty insurance is following the same path as bonds, mortgages and equities

Staying ahead – why Accelerant is focused on evolution, not just competition
