Advice across the insurance value chain

Six areas of practice, each led by advisers with direct experience of the question at hand.

Strategy and growth

For insurers, MGAs and insurtechs

Where to compete and how to grow. We advise on positioning, products, distribution and partnerships, and on the plans that bring them together.

  • Market entry and positioning
  • Product and proposition design
  • Business plans and investor materials

Underwriting and capacity

For MGAs, carriers and capacity providers

How risk is written and who backs it. We help underwriting businesses build the case for capacity and the structures that sustain it.

  • Capacity strategy and London market access
  • Delegated authority and binder structures
  • Underwriting performance reviews

Captives and risk financing

For corporates and risk owners

Whether, when and how to retain risk. We test captive options against governance, capital and risk appetite as rigorously as against cost.

  • Captive feasibility studies
  • Cell and protected cell options
  • Risk retention and financing strategy

Market intelligence and economics

For boards and leadership teams

Evidence for consequential decisions. Economic analysis and market intelligence that make regulated, competitive and changing markets easier to read.

  • Market and competitor analysis
  • Economic and scenario analysis
  • Board briefings on market change

Cross-border and market access

For international carriers, MGAs and investors

Bringing business to and from London. Advice for businesses coming to the London market from overseas, and for London businesses looking abroad.

  • London market entry strategy
  • Partner and counterparty assessment
  • Market landscape reviews

Executive education

For business schools and leadership teams

Sharper thinking about risk and decisions. Teaching and workshops on insurance, risk, strategy, AI and decision-making for academic and professional audiences.

How we work

A clear method, applied by senior people at every stage.

  1. Frame the decision

    We agree the question, the options and what a good outcome looks like with the people who own it.

  2. Build the evidence

    Market, economic, underwriting and operational analysis, with every assumption made explicit and tested.

  3. Recommend clearly

    We set out the trade-offs plainly and make a recommendation a board can act on.

  4. Stay to deliver

    We support implementation through to the first results, so the decision holds in practice.

Senior advisers, working as one.

Sariel Partners is organised around mandates. For each engagement we bring together senior practitioners with direct experience of the question at hand, from underwriting and distribution to economics, strategy and education.

Clients deal with senior people throughout, and every piece of work is held to the same standard of excellence.

Perspectives

Short views on questions our clients bring to us.

Capacity

Capacity follows evidence

Capacity providers back underwriters whose data they trust. A credible loss record, clean bordereaux and clear authority do more to secure a line than any presentation. New MGAs should build that case before they go to market.

Captives

A captive is a governance decision first

Captives can lower the cost of risk and sharpen risk management, but only when the parent is ready to own the risk it keeps. Feasibility work should test governance, capital and appetite as hard as tax and cost.

Distribution

Distribution decides most strategies

Good products fail for want of a route to market. Strategy work should start with who will sell, recommend or embed the cover, and what they need to do it well.

AI and underwriting

AI changes the questions, not the accountability

Models can price, triage and summarise faster than any team. The judgement about which risks to write, and on what terms, still sits with the people who answer for the result.
