Independent specialist re/insurance broker Miller has introduced MillerBoost, a smart follow facility aimed at improving the speed and efficiency of property placements in the London Market.
MillerBoost is powered by InsurX’s trading infrastructure and provides access to exclusive A+ rated Lloyd’s capacity. It offers global coverage and is currently available across Miller’s property portfolios.
According to Miller, the facility enables brokers to triage and quote risks more quickly, allowing for accelerated placement timelines for both retail and wholesale clients. By combining data-led automation with curated carrier support, MillerBoost aims to supplement open-market shared and layered placements with additional capacity.
The facility is intended to give carriers enhanced visibility and control over the risks they underwrite, using data insights to support underwriting decisions and drive placement outcomes.
The introduction of MillerBoost aligns with broader adoption of algorithmic underwriting practices across the London Market. In recent years, platforms such as InsurX have helped accelerate the use of algorithmic trading by enabling brokers and insurers to syndicate risks with greater speed and scale.
InsurX reports that its system delivers a high rate of responsiveness for brokers operating in real time. The company has stated that 61% of quotes are returned within 15 minutes, with 84% completed within an hour, and nearly all responses – 99.7% – delivered within two hours.
When InsurX first launched its digital capacity exchange tailored for the London Market, it was backed by an initial commitment to write £20 million in gross written premiums. The platform's design focuses on automating follow capacity for property and specialty classes, using an algorithmic underwriting model to match carrier preferences with incoming risks.
Matt Keeping, head of property and casualty at Miller, said MillerBoost allows the firm to provide faster quotes, improve placement efficiency, and access exclusive capacity.
“As we continue to grow our specialist capabilities across a diverse property portfolio, we chose to power the facility with InsurX’s market leading smart follow technology to equip our brokers with a data-led competitive edge, which has already proven invaluable,” Keeping said.
