Profile bio

About Alexander Margolin

As a Chartered Insurance Broker with over 10 years of experience, I founded Sioma, an independent broker based in Mayfair, to provide the best service and advice to my clients. Sioma specializes in offering technical insurance solutions, best-fit insurance policies, and wider risk management support to complex commercial enterprises and ultra-high-net-worth individuals. I have a strong background in underwriting, broking, claims, and risk management, which enables me to deliver customized and effective solutions for my clients. I have been recognized for my achievements and contributions to the insurance industry, winning the Broker of the Year Award in 2021 (under 35) and leading Sioma to become the Fastest Growing Brokerage in the UK in 2023. I am also passionate about sharing my knowledge and skills with the insurance community, by providing technical training courses to the Chartered Insurance Institute and serving as a board member for the British Insurance Brokers Association (BIBA) SME Advisory Board. Besides insurance, I am committed to making a positive impact in the world, by running Made With Hope, a charity in Tanzania supporting 11 schools and 6,000 children, to use education to break the cycle of poverty. I am also an angel investor and a strategic advisor to several startups, where I leverage my expertise and network to help them grow and scale.

Listed skills include Property And Casualty Insurance, Underwriting, Insurance, General Insurance, and 9 others.
