Specialist venture capital firm BP Marsh, an early-stage financial services business, has acquired an additional 2% equity stake in Pantheon, a full-service London market wholesale insurance broker, from founders Robert Dowman and Michael Lee, valuing the equity at £275m.
BP Marsh originally invested in Pantheon in June 2023, working with Robert Dowman to acquire a 25% stake in the newly formed company.
The joint venture has since made a number of incremental investments to increase its stake, bringing its total stake in Pantheon to 41%. The transaction is funded from BP Marsh’s existing cash reserves.
Since the investment, Pantheon has grown into a full-service London market wholesale insurance broker, branching out into other market segments and increasing earnings diversification.
Pantheon, which initially launched in 2023 with a primary focus on global casualty and specialty product lines, has generated consistently strong EBITDA margins, reflecting a highly scalable and capital-light model, with continued high levels of cash generation supporting reinvestment and growth.
In addition, BP Marsh said the broker’s ability to attract multiple high-quality veteran producers has significantly enhanced its revenue-generating capabilities.
Pantheon also maintains relationships with global brokers, MGAs and operators, supports high levels of recurring revenue, and has demonstrated strong momentum through organic growth and new business wins.
The broker said revenue rose to almost £30m in FY26, up from around £23.8m in FY25, with full-year pre-tax profits expected to exceed £15m.
Robert Dowman, founder and chief executive officer (CEO) of Pantheon, commented: “BP Marsh’s continued support is a strong endorsement of Pantheon’s growth since launch. We have made significant progress in building a diverse professional brokerage platform, expanding our capabilities and attracting high-quality teams, which together have driven our growth and performance. With a solid foundation and clear momentum across the business, we will continue to focus on expanding the platform and delivering long-term value to our customers and partners.”
Dan Topping, CEO of BP Marsh and nominated director of Pantheon’s board, added: “We are delighted to further increase our investment in Pantheon and continue to support the business. Since our initial investment, Pantheon has made excellent progress, combining strong financial performance with the successful execution of its growth strategy.
“The business has rapidly expanded its platform, expanded its product range, and demonstrated the strength of its monetization model. We are confident in Pantheon’s long-term potential and look forward to supporting it as it continues to expand.”
