’This deployment has taken four months from initial conversation to deployment,’ says head
Chapman and Stacey Underwriting has launched a liability product onto Open GI’s platform via imarket.

The launch marks the first MGA product to go live through imarket this year.
Paul Wingfield, managing director at Chapman and Stacey, said: “This is the first of a range of products we plan to deploy in 2026 using imarket as we believe continuing to support broker system panels maintains our opportunity to work with brokers in a way that is integrated as seamlessly as possible into their back office environment with no extra ‘keying’.”
Simon Macray, director of insurer relations at Open GI, added: “Adding Chapman and Stacey’s liability product to our suite via imarket is a huge positive for Open GI and our partners.
“We’re also pleased we’ve been able to support the product delivery in such a speedy timeframe.”
Conversation to deployment
imarket connects 2,000 brokers to insurer products and trades over 550,000 policies annually, generating over £450m gross written premium (GWP).
