Flood & water-risk intelligence for insurance.

We work on one problem: measuring flood and water risk well enough for insurers, reinsurers, and risk pools to price it, reserve against it, and hold capital for it. The work spans pluvial, fluvial, coastal, and groundwater perils.

Flood risk is a hydraulic problem.

Rainfall, sea level, and land-surface response are shifting faster than flood maps are re-issued. The models the industry relies on were built for a more stationary world. Our work is to build flood and water-risk models that hold up under those conditions: grounded in hydrology and 2D hydrodynamics, calibrated against gauges, satellite extents, and claims, and built to be checked.

  1. I

    Hydraulics before precedent

    Models begin from rainfall-runoff physics and shallow-water dynamics, then calibrate to gauges, satellite extents, and claims in that order.

  2. II

    Decision-grade uncertainty

    Every output ships with its provenance, assumption set, and a full quantile view, so decision-makers see the whole distribution.

  3. III

    Reproducible by construction

    Data lineage, model weights, and scenario definitions are versioned artefacts. A regulator, a reinsurer, and a researcher should all arrive at the same number.

  4. IV

    Catchments are the unit of analysis

    Flood risk lives in the joint distribution across rivers, drains, and coastlines. We model compound events, catchment-scale correlation, and defence failure across the full joint surface.

Who we work with.

We work with teams carrying flood and water risk on their books, and with partners who want to build the modelling alongside us rather than buy it as a black box.

  • i.Primary insurers

    Flood pricing, underwriting, and portfolio steering across personal lines, commercial property, and SME.

  • ii.Reinsurers & retrocessionaires

    Flood treaty structuring, cedent review, and tail-risk quantification under non-stationary rainfall and sea level.

  • iii.Flood pools & public schemes

    Sovereign, mutual, and parametric flood programmes seeking transparent, auditable water-risk models.

  • iv.Capital & ILS investors

    Cat-bond structurers, ILS funds, and asset owners pricing flood-exposed property and infrastructure portfolios.
