The Demex Group

Demex is a technology-enabled Managing General Agent (MGA) offering unique stoploss protection for secondary perils based upon a proprietary Proxy Claims Index.

Demex enables insurance companies to transfer attritional climate risk by modeling, structuring, and settling the accumulation of small- and medium-sized claims caused by weather. 

The Demex Group was founded in 2020 by Ed Byrns. The company is headquartered in Washington, District of Columbia.


Demex operates at the intersection of climate, insurance, and technology, with a groundbreaking approach to weather risk transfer for secondary weather perils. In 2022, Demex created Retained Climate Risk Reinsurance, which is a unique stop loss risk transfer product that settles based upon Demex's proprietary Proxy Claims Index.


Demex powers complex data analysis required to rapidly deliver customized transactional platforms for clients and risk providers, creatively analyze client exposures and establish bespoke risk solutions, efficiently transfer risk to pre-certified risk carriers, and proactively deepen business insight through solutions monitoring and learning loops.


Demex RCR Reinsurance solution is the only mechanism in the market to reinsure SCS and other Secondary Peril losses. Two of the top three global reinsurance brokers are already selling Demex’s storm product to their insurer customers.


Demex is backed by Anthemis Group, IA Capital Group, Blue Bear Capital, and QBE Ventures. The company raised $5M in a new round Aug 15, 2023. This brings Demex's total funding to $18.2M to date.
