hyperexponential (hx), a pricing and underwriting platform for re/insurers, has expanded its strategic partnership with Aviva to accelerate the British insurers’ AI-powered underwriting and pricing transformation.
This builds on the announcement in July 2025, with Aviva leading hx’s AI beta programme, spearheading the exploration of the newly launched Actuarial Agent within hx Renew.
Aviva is now set to adopt hx’s full range of new capabilities, including Triage, Underwriting Agent and Portfolio Intelligence, these will be deployed across Aviva’s rating tools to support its Global Corporate & Specialty (GCS) underwriters.
The expanded partnership will strengthen Aviva’s pricing accuracy, streamline complex workflows, and unlock new insight and efficiencies in underwriting decision-making and portfolio optimisation, helping to maximise benefits for Aviva’s GCS brokers and clients.
Aviva now has 23 models live in hx across a wide range of commercial lines, including Corporate Property, Cyber and Marine Cargo.
Karen Dayal, Chief Underwriting Officer for Commercial Lines at Aviva, said, “By partnering with hyperexponential, we’re making intelligent underwriting a reality for our Global Corporate & Specialty business. The platform enables our underwriters to make smarter, AI-augmented decisions on individual risks while streamlining manual processes. It will also give our portfolio managers the insights they need to drive stronger pricing and deliver superior portfolio outcomes. Together, these capabilities help Aviva get ready for the next generation of underwriting and strengthen our leadership role in London Market pricing innovation – delivering even greater value for GCS brokers and clients.”
Amrit Santhirasenan, CEO and Co-founder of hyperexponential, added, “The Aviva team is raising the bar – showing that it’s possible to deliver cutting-edge transformation at scale, combining exceptional product and service growth with technology-driven improvements. We’ve been privileged to be part of this journey so far, and now further strengthen our partnership with Aviva as it leads the way in applying AI to complex pricing and underwriting challenges. It’s extremely rewarding to be part of a transformation that will help unlock meaningful value for Aviva’s teams, clients and brokers.”
