hyperexponential

hyperexponential, trading as hx, builds a pricing and underwriting platform aimed specifically at commercial property and casualty insurance, and it claims top global carriers trust it for underwriting decisions across more than 75 billion dollars in annual commercial P&C premium. Its stated goal is precise and commercially legible: more risks priced, more book written and a better loss ratio, with the same underwriting team. That framing targets capacity rather than headcount, which is the real constraint in specialty underwriting where experienced underwriters cannot simply be hired at will.

The platform is agentic and covers end-to-end underwriting work rather than one step. Submission triage takes a risk from inbox to ranked queue before an underwriter opens a file, with overnight queue processing, bordereaux ingestion, ACORD extraction and appetite scoring. This is the highest-value automation in the workflow, because underwriters otherwise spend substantial time reading submissions they will ultimately decline. Complex risk assessment runs bespoke actuarial models, validates against appetite and flags decision bounds, supporting quote generation, novel risk pricing, rate justification and what-if scenarios.

Renewals pull history, reprice the account and draft terms, with a renewal pipeline, rate change rationale and senior referral flagging. Portfolio monitoring tracks exposure, concentration and drift across the book, with book-shape reporting, concentration limits, exposure alerts and rate change analysis. Wording and regulation monitoring is a distinctive inclusion, running regulatory sweeps, monitoring wording updates, tracking Lloyd's bulletins and drafting responses, which reflects genuine London market knowledge. Actuarial modelling covers batch portfolio runs, loss curve benchmarking, model re-parameterisation and version publishing. Pricing is not published and evaluation begins with a booked demo.
