The way we work with clients starts from three principles.
Our broking experience in property, specialty and marine lines lets us manage even the most demanding risks systematically.
Fast decisions and immediate responses protect our clients’ time.
We don’t stop at placing a policy. We analyse your business structure and risk together and propose practical business solutions.
From direct insurance to reinsurance, from Korea to overseas markets. We stay with your risk from beginning to end.






Based on analysis of your business and its risks, we propose the right cover and sums insured and design an insurance programme optimised for you.
We compare terms and premiums across insurers to conclude the most rational insurance contract.
Through policy review and renewal management we check the terms and cover of your contracts, and support claims negotiations with insurers when a loss occurs.
To spread the risks of insurance contracts securely, we structure facultative and treaty programmes with reinsurers in Korea and abroad and negotiate their terms.
We connect large and specialty risks that are hard to place in Korea directly with leading overseas reinsurers, helping secure stable underwriting capacity.
We analyse insurers’ retained risks and portfolios, propose appropriate retention levels and reinsurance structures, and support negotiations for better terms at renewal.
We focus on sectors where buying a policy is not enough, and precise analysis and design make the difference.
