OAK Global Secures Lloyd’s Approval for New Portfolio Underwriting Unit OAK Partnerships

OAK Global has secured Lloyd’s approval to launch OAK Partnerships, a new strategic business unit designed to provide multi-class capacity and underwriting expertise for insurance risk portfolios. For brokers and MGAs, this initiative offers a single entry point to Lloyd’s security backed by proprietary risk analytics, while diversifying OAK’s capital exposure through a lower-volatility strategy starting in 2027.

What was announced

OAK Global has received formal approval from Lloyd’s to establish OAK Partnerships, a strategic business unit focused on providing multi-class expertise and capacity for portfolios of insurance risk. This unit is specifically designed to cater to leading underwriting partners who require stable, long-term cornerstone capacity. The financial backing for these portfolios will be provided by OAK Syndicate 1440, with the official commencement of risk inception scheduled for 1st January 2027.

The scope of OAK Partnerships is broad, covering four primary pillars of the insurance market: Property, Specialty, Credit, and Casualty classes of business. By offering these diverse classes through a single underwriting relationship, the unit aims to reduce the administrative and relationship-management burden on distribution partners. A key differentiator for the unit is its reliance on OAK Global’s proprietary technology platform. This system utilizes a holistic industry dataset to conduct market-leading risk analytics. The firm has committed to a transparent data model where the benefits of this analysis—such as portfolio benchmarking and deep-dive insights—are shared directly back with the partners.

Elisabeth Groehe has joined OAK Global as the Chief Underwriting Officer of OAK Partnerships to lead this initiative. Groehe brings over a decade of underwriting leadership experience specifically within the portfolio insurance sector. In addition to her CUO role, she will act as Joint Active Underwriter for Syndicate 1440. She will work alongside Roland Morse, who serves as the Chief Underwriting Officer of OAK Enterprise and the other Joint Active Underwriter for the syndicate.

"OAK Partnerships is an exciting expansion of OAK Global’s offering to the market. It will bring our technology-enabled underwriting expertise to a new cohort of underwriting partners, offering Lloyd’s capacity for multi-class portfolios of profitable risk. For our capital providers, this will further diversify OAK Global’s offering by adding a lower volatility underwriting strategy and risk profile that is highly complementary to our existing reinsurance and retrocession portfolios."

Cathal Carr, Founder, CEO and Group CUO of OAK Global.

The companies involved

OAK Global is a global risk partner that operates within the Lloyd’s of London insurance market, utilizing two dedicated syndicates to deploy capacity. The firm has built its reputation on a technology-first approach to underwriting, aiming to blend traditional insurance expertise with modern data science. Before the launch of OAK Partnerships, the group’s primary underwriting activities were concentrated within OAK Enterprise, a division focused on reinsurance and retrocession. This existing business typically involves higher volatility risks, making the new unit's focus on portfolio insurance a strategic move to balance the group’s overall risk profile.

The company is led by its founder, Cathal Carr, who holds the titles of CEO and Group Chief Underwriting Officer. Under his direction, OAK Global has emphasized the development of internal technology to gain a competitive edge in risk selection and pricing. The firm’s presence at Lloyd’s is bolstered by its ability to provide significant security and licensing to its partners. By expanding into the portfolio space, OAK Global is positioning itself as a comprehensive provider for MGAs and brokers who need more than just capital, but also the analytical tools to manage their books of business effectively in an increasingly complex regulatory environment.

What this means from an insurtech perspective

From an insurtech perspective, OAK Partnerships represents a shift toward "capacity-as-a-service," where the value proposition is as much about data intelligence as it is about the balance sheet. By promising to share portfolio analysis and benchmarking back with partners, OAK Global is addressing a long-standing friction point in the MGA-carrier relationship: the information asymmetry that often hinders long-term stability. This move puts pressure on incumbent Lloyd’s players who still rely on manual oversight and legacy core systems that cannot easily ingest or analyze granular risk data at scale.

For the broader insurance value chain, this launch underscores the necessity of integrating advanced analytics into the underwriting process to manage loss ratios in a volatile market. It raises a critical question for the sector: will the "cornerstone" capacity of the future be defined by the size of the syndicate or the sophistication of its data platform? As OAK Global moves toward its 2027 inception date, the market will likely see a heightened focus on how proprietary datasets can be used to lower volatility in casualty and specialty lines, potentially shifting the power dynamic between traditional reinsurers and technology-led syndicates.
