What Alesco does
Alesco Risk Management Services Limited is a London-headquartered independent insurance broker and risk consultancy founded in 2008, operating as an appointed representative of Arthur J. Gallagher (UK) Limited. The firm places large and complex risks on a direct and wholesale basis through the London Market and Lloyd's syndicates, working with underwriters in key global insurance hubs including Houston, Dubai (DIFC) and Singapore, with a Swedish branch (trading as Alesco Europe) under Arthur J Gallagher Nordic AB. Its product suite spans insurance brokerage, risk consulting, claims management, and alternative risk transfer (captives, parametric solutions, derivatives) across six industry verticals: Natural Resources (upstream, downstream, midstream, renewables, power, energy transition, integrated energy), Construction, Marine & Cargo, Mining, Casualty, and Property & Special Risks. The Natural Resources team alone comprises 95+ specialists serving 600+ clients globally, with 95+ specialists and measurable client outcomes including 10-25% premium reductions on well-engineered risks.
Revenue is generated through insurance brokerage commissions on placements (property, liability, accident and health, contingency) and professional services fees for risk consulting, analytics, captive advisory, and actuarial support. Pricing is bespoke per client risk assessment with annual billing cadence. The go-to-market is enterprise field sales, supported by wholesale broker partnerships worldwide, with thought-leadership content (H1/H2 market updates) and direct client engagement through regional hubs. The underlying technology stack is built around partnerships: Eigen Prism provides real-time natural catastrophe modelling, and the firm is exploring blockchain-based smart contracts and parametric trigger structures to expand into automated claims and previously uninsurable risk categories. The client base is concentrated in complex, multi-line commercial risks for energy, mining, marine, construction, and casualty buyers globally, with North America, Europe, the Middle East, Latin America, and Australia as served regions.
