About Us

Global Risk Partners Limited (GRP) was established in 2013 by Peter Cullum, Chairman of GRP and David Margrett, Chief Executive of GRP.

David Margrett and Stephen Ross, Chief Operating Officer of GRP, identified a significant opportunity in the specialty market for brokers, Managing General Agents (MGAs) and teams who want to release equity from their business. GRP meets this need by offering solutions to existing shareholders who wish to exit, either partially or completely. Existing management teams who want to continue to develop the business can benefit from investment to grow the business organically.

We acquire brokers, MGAs, portfolios and teams which have niche, non-commoditised, specialty business and strong profitability.

GRP is backed by private equity firm, Penta Capital LLP and Peter Cullum is a co-investor.

Peter Cullum CBE, MSc, MBA, FCII, PhD - Chairman

Peter co-founded Global Risk Partners Limited (GRP) in October 2013 and remains the largest individual shareholder.
He began his insurance career in 1969, working for Royal Insurance Group, Commercial Union and ITT London & Edinburgh, before joining Economic Insurance in 1991 to return the company to profitability. He led the management buyout of Economic which was sold to Hiscox in 1996.
In 1997, Peter created Towergate. It was an innovative new model for the insurance industry and grew to become one of Europe’s largest independently owned insurance intermediaries, controlling premium in excess of £3billion.
In 2006 he created Capital Cullum Ventures (CCV), an independently owned group of insurance intermediaries which grew significantly through acquisition of quality regional brokers and is now part of Towergate. Peter also set up the Towergate Charitable Foundation in 2005 which has since raised more than £7m for charitable causes.
In 2005, Peter won the Ernst &Young Entrepreneur of the Year award and in 2009, established the Peter Cullum Centre for Entrepreneurship with Cass Business School, as a focal point for budding and established entrepreneurs. The Centre helps develop the skills and connections needed to make great business ideas succeed.
Peter has pledged £10m risk capital to the Cass Entrepreneurship Fund, which acts as an investment fund for the best start up and early stage businesses. In December 2010, Peter was awarded the CBE for his contribution to business, entrepreneurship and charitable causes. He is Vice President of The National Autistic Society and has funded the building of four specialist school units for children on the Autism spectrum in Surrey.
