eXpect better

We’re rewriting the DUA book. Delivering professionally presented, profitable and niche lines of business to insurer partners.

The Problem

For too long, insurers have had to suffer poorly presented business plans, offering little difference for their portfolio and competing for market share with existing business.

We believe you have a right to expect more. Much more.

Profitable, professional business


Every opportunity we present to you has been extensively analysed, has a genuine point of difference and will be presented in a professional business plan. Making your decision making process easier.

Genuinely different

We’re committed to only providing you with niche, profitable and innovative opportunities in new markets, territories and lines of business that are currently underserved.

Accurately analysed

Our proprietary automated actuarial platform analyses the data of prospects at the pre-agreement stage, ensuring the numbers stack up.

Perfectly presented

Everything we present to you will be wrapped up in the eXponential standard business plan, allowing you to make the right call, based on the full picture.

Value for everyone


We think that the standard DUA offer simply isn’t good enough, delivering little value for you, MGAs and the policyholder. So, we’ve set about building something that does.

We offer a wide range of support functions to help growth minded MGAs achieve their goals. eXponential will help the whole value chain be more efficient, more successful and ultimately more profitable.

eXponential has been a key factor in the success of Allianz Partners Health in the UK. We have continued to grow rapidly with the support of eXponential and I believe this will continue. They find solutions to problems that seem unfixable. It is a pleasure working with them.

Our team

eXtraordinary as standard

When we were building eXponential, we knew that standard wasn’t good enough. And that very much goes for our people. Our team is made up of a vastly experienced, deliberately diverse and passionately innovative collection of people whose unique skillsets are combined to help you access new and profitable distribution channels.

The new standard

Setting the bar high

eXponential offers access to a wide range of teams from across the Aventum family. So, whatever support MGAs need, it’s ready and waiting for them. All designed to make their opportunities more appealing to you.

The marketing studio

The Marketing Studio provides creative support to our MGA partners, helping them to capture the attention of prospective clients and partners.

Data Science and Analytics

Artificial Digital Actuary, or ADA for short. A proprietary data tool, it uses AI technology to ingest data, generate automated modelling and produce truly meaningful insight. Helping you make better-informed decisions.


Our goal is to change the perception of compliance - no longer something to be feared, but something to be embraced to help deliver the best outcomes for our customers.

Delegated Underwriting Authority

Distributing your capacity is a privilege that we will never take for granted. That is why every MGA we work with must meet the standards set by our DUA team. And that is why we are the perfect blend of unparalleled technical expertise and skilled relationship management.

Digital Distribution

We understand that success comes from maximising distribution channels. Our in-house digital development team can help our MGA partners to build intuitive online quote and bind solutions quickly, extending their reach and maximising efficiency for all.

Claims Management

There’s no getting away from the fact that claims management is a crucial part in building reputation. Our team has years of international (re)insurance experience across multiple classes of business and will work with your claims experts to ensure the best possible client outcomes.

Automated Data Processing

There’s no hiding from the fact that data integrity and processing can be unnecessarily difficult. We forever invest in our operational infrastructure streamlining bordereaux returns, providing you with meaningful and quality data. First time. Every time.
