FloodFlash

FloodFlash is a London-headquartered parametric commercial flood insurance MGA and Lloyd's coverholder that writes fixed-payout, sensor-triggered flood cover for small and mid-market UK and US businesses in flood-exposed locations that traditional indemnity markets underserve or decline. It was founded in 2017 by Adam Rimmer (ex-RMS Capital Markets) and Dr Ian Bartholomew (ex-RMS; PhD in glaciology, Edinburgh; M.Phil in polar studies, Cambridge). Both founders spent roughly eleven combined years modelling and structuring parametric catastrophe bonds before building FloodFlash around the premise that the same trigger mechanics used for sovereign and large-corporate cat-bond structures could be compressed into an SME policy backed by a physical IoT sensor rather than a third-party hazard index.

What the product actually does. FloodFlash installs a proprietary ultrasonic depth sensor outside the insured premises. The sensor measures standing-water depth to 5 mm accuracy, runs on a 12-year battery, and transmits readings to FloodFlash via mobile network. Each policy specifies a contracted trigger depth and a contracted fixed payout. When floodwater at the sensor reaches trigger depth, the claim is validated automatically and the lump sum is paid to the insured — typically within 48 hours, with the fastest recorded settlement reported at 3 hours 50 minutes. Between February 2020 and October 2022, FloodFlash paid 67% of triggered claims within 48 hours. The product covers commercial property, business-interruption components, and specialty segments such as auto-dealer lot inventory and golf-course grounds; a dedicated US auto-dealer product launched in May 2024.

Why this fiche sits in the underwriting-workstation layer (and not reinsurance). FloodFlash's commercial unit is the policy — it is a risk-bearing MGA, not a piece of software — but unlike Arbol or Parametrix the centre of gravity is closer to primary-line commercial underwriting with a tightly defined product form and a physical sensor estate that FloodFlash owns and services. It does not structure cat bonds, it does not operate a Bermuda MGU, and it does not act as a reinsurance originator. Post-acquisition it sits under NormanMax's Syndicate 3939 — the first pure-parametric syndicate at Lloyd's — as a multi-peril parametric workstation (flood sensor + wind anemometer), which reinforces the underwriting-workstation framing over a pure reinsurance classification.

Capacity stack. Capacity has been Lloyd's-centric throughout. At the 2018 UK launch, FloodFlash placed the parametric flood policy onto Everest Re's syndicate at Lloyd's. Munich Re took the lead role on the core UK SME book following the 2021 partnership announcement and, in June 2024, expanded FloodFlash's US binder through Munich Re Specialty's Global Markets division to all mainland US locations (from an initial ten-state footprint), writing parametric flood excess of the NFIP. Hiscox joined the US capacity panel in 2023. Since February 2025 the risk sits alongside NormanMax's parametric wind book on Syndicate 3939, which is structured specifically to carry parametric paper at Lloyd's.

Funding. Total disclosed venture funding is approximately $23M across two priced rounds: a £1.9M seed in August 2018 led by Pentech Ventures, LocalGlobe, and Insurtech Gateway; and a $15M Series A announced in February 2022 led by Chicago-based Buoyant Ventures, with Munich Re Ventures (San Francisco), MS&AD Ventures, Sony Financial Ventures via Global Brain, PropTech1 (Berlin), and the three existing seed backers participating. No priced growth round was announced before the NormanMax deal; the acquisition in February 2025 (FCA approval granted April 2025, terms undisclosed) is the liquidity event for the Series A syndicate.

MGA-vs-platform caveat. The same caveat that applies to Jumpstart (parametric earthquake), Parametrix (parametric cloud outage), and Arbol (parametric climate) applies here. FloodFlash's "platform" — the ultrasonic sensor estate, the trigger-calculation logic, the mobile-network telemetry, the rapid-settlement workflow — is marketed as technology, but the commercial relationship that actually ships is parametric flood capacity bundled with the sensor infrastructure, not licensable software. A carrier looking to embed sensor-triggered flood logic into its own underwriting workstation cannot buy FloodFlash's stack independently of buying the policy. Under NormanMax ownership this bundling is tightened further: the sensor data feed is integrated with NormanMax's parametric wind anemometer programme as a multi-peril capacity offering rather than unbundled as a carrier-facing data product.

Basis-risk caveat. Like every parametric product form, FloodFlash pays on an index trigger — water reaching a contracted depth at the sensor — not on inspected loss. A shallow flood that meets trigger but causes limited damage produces a full payout; a deep flood that damages property but fails to reach the contracted trigger depth produces no payout. FloodFlash positions the product as fast post-event liquidity and a cover option for risks that traditional indemnity flood insurance has priced out of the market, not as a like-for-like replacement for indemnity cover.

Analyst gap. No Gartner, Celent, Forrester, or Novarica leader-quadrant placement surfaces in public indexing. Coverage is concentrated in reinsurance and insurtech trade press — Artemis (primary source for capacity, UK flood-event triggers during Storm Henk in January 2024, and the NormanMax acquisition narrative), Reinsurance News, Insurance Journal, Intelligent Insurer, Insurance Times, The Insurer — plus one TIME magazine feature (January 2024) positioning FloodFlash in the climate-adaptation and insurance-protection-gap narrative, and Lloyd's Lab alumni coverage on lloyds.com. Financial Times coverage of FloodFlash specifically does not surface in public indexing as of 2026-04-22.
