Backed by Haatch and the South West Investment Fund, the startup automates the most painful parts of mortgage advice—starting with admin.
Startup JammJar is coming out of stealth with a platform designed to overhaul how mortgage brokers operate—by eliminating the admin that slows them down. With backing from early-stage investors Haatch and the British Business Bank’s South West Investment Fund via fund manager The FSE Group, the company is launching publicly today with a goal to become the Al operating system for the UK's mortgage advice industry.
The UK's mortgage market is worth £l .9 billion annually, with over 85% of mortgages arranged through brokers. But the tools those brokers rely on are "built for compliance, not productivity," says JammJar co-founder and CEO Karl Griffin. That means 14+ hours a week spent on repetitive tasks—data entry, note-taking, document management—often across siloed systems.
JammJar replaces that with a single Al-native platform that listens to broker calls, updates the CRM in real time, auto-generates documents and suitability notes, and even matches clients with suitable lenders based on live eligibility criteria.
"Most broker software hasn't evolved in a decade. We're rebuilding the tech stack around the advisor—not the admin," says Karl Griffin, CEO, a former enterprise sales lead at Zoopla and founder of a digital mortgage firm.
JammJar is designed for how brokers actually work—by integrating phone calls, video, email, CRM, and sourcing in one place. As soon as an advisor finishes a client call, the system generates a complete Fact-Find and updates the case record, automatically.
"It's been transformational," said Felicity Chappell, Director at Mortgage Select SW, an early customer. "The Al writes the Fact-Find instantly. Our advisors can focus on advice, not forms—and our clients get a smoother, faster experience."
JammJar has already signed its first customers through a closed beta and is now opening a waitlist. Investors are betting that it can scale fast in a market long overdue for innovation.
"JammJar are addressing a huge pain for mortgage advisors. Over 80% of clients fall out of the process due to clunky, manual workflows," said Charlie Weavers-Wright of Haatch. "The team have deep industry experience—we're proud to back them early."
"We were deeply impressed by the exceptional quality of the founding team and the groundbreaking solutions they've brought to a market ripe for disruption," added Matt Browning of the South West Investment Fund, via appointed fund manager The FSE Group.
Paul Jones, Senior Investment Manager from the British Business Bank said: “Supporting ambitious and innovative businesses like JammJar is what the South West Investment Fund is designed to do and we wish the team every success with the launch of their AI-powered platform.”
The UK has over 37,000 regulated mortgage advisors, with most firms still using outdated CRMs or off-the-shelf solutions not built for financial services. Many operate virtually, under pressure from both compliance requirements and consumer demand for digital experiences.
Griffin believes that gives JammJar a wedge: "We're not building a generic CRM or shiny chatbot. We're building infrastructure—one that brokers actually want to use because it saves time, improves compliance, and helps them grow."
