Parametrix

Parametrix is a parametric managing general agent and Lloyd's cover holder, dual-headquartered in New York and Tel Aviv, that writes cloud outage, data centre, and digital business-interruption cover for enterprises dependent on hyperscaler infrastructure (AWS, Azure, Google Cloud) and the wider SaaS/PaaS/IaaS supply chain. It was founded at the end of 2019 by Yonatan Hatzor (CEO), Neta Rozy, Ori Cohen, and Tamir Carmel, and went live in the US market in 2020 through the Lloyd's Product Innovation Facility, with Tokio Marine Kiln as lead syndicate and RenaissanceRe participating.

Why this fiche sits in the reinsurance layer (and not rating, and not underwriting-workstation). The same logic that applied to Arbol applies here. Parametrix's commercial unit is capacity, not a licensable tool. Its AI-driven monitoring infrastructure — real-time tracking of roughly 7,000 cloud-based technology companies and ~750 data centres — exists to define and settle the parametric trigger on policies Parametrix itself writes or on the Cumulus Re cat-bond series it structures for Hannover Re. A carrier or large broker cannot buy the Parametrix tech stack independently of buying, ceding to, or co-originating Parametrix-branded cover. A case could be made for an underwriting-workstation classification given the depth of the submission and pricing tooling, but the centre of gravity is clearly risk-bearing: MGA pen, Lloyd's cover holder status, and a catastrophe-bond programme.

Funding. Total disclosed funding is approximately $45M. The December 2025 Series B of $27M was led by Mundi Ventures, FirstMark Capital, and Hannover Digital Investments (the corporate venture arm of HDI Group, Hannover Re's parent), with F2 Venture Capital and several strategic backers participating. Prior rounds included a Series A led by F2 Venture Capital. Parametrix reported 300% top-line growth in 2025 alongside the Series B, though absolute GWP is not publicly disclosed.

Capacity stack. The reinsurance panel is the most substantive signal of institutional acceptance. Hannover Re sits at the centre — both as a direct capacity provider and as the sponsor of the Cumulus Re parametric cloud-outage cat bond series that Parametrix structures and operates as calculation agent: $13.75M in the inaugural 2024-1 series, $20M in the 2025-1 renewal, and $35M in Cumulus Re III (2026-27). Cumulus Re was the first cyber cat bond with a purely cloud-risk focus and remains the only cyber cat bond using a parametric trigger. On the Lloyd's side, Tokio Marine Kiln, RenaissanceRe, and Apollo ibott Syndicate 1971 are named panel members supporting Parametrix's US underwriting.

The CrowdStrike moment. On 19 July 2024, a faulty CrowdStrike Falcon sensor update caused a global Windows BSOD event that grounded airlines, shut hospital systems, and knocked out payment infrastructure. Parametrix became one of the most-cited loss estimators of the event: its widely-reported analysis put direct financial loss to the US Fortune 500 (ex-Microsoft) at approximately $5.4B, with insured losses of $540M–$1.08B across the cyber market — numbers that were picked up by CNN, Reuters, Insurance Journal, Reinsurance Business, and much of the cyber trade press. That event validated the category case — single third-party digital dependencies can produce correlated, cross-industry interruption loss of a scale that traditional indemnity cyber BI struggles to settle quickly — and, importantly for Parametrix, converted awareness into broker demand visible in the 2025 numbers.

MGA-vs-platform duality — the caveat. The same caveat applied to Shepherd, Descartes Underwriting, and Arbol applies here: Parametrix's "platform" is marketed as technology, but the commercial relationship that ships is parametric capacity and reinsurance structuring, not software. A reader shopping for a cyber underwriting workstation, a SaaS claims platform, or a standalone cloud-outage monitoring feed should read this fiche as a capacity-and-product story, not as a vendor selection. The monitoring, the AI pricing, the index definition, and the claims-adjudication logic are bundled with the policy.

Analyst gap. No Gartner, Celent, Forrester, or Novarica leader-quadrant placement surfaces in public indexing for 2023-2026. Coverage is concentrated in reinsurance and insurtech trade press — Artemis (primary source for the cat-bond and capacity narrative), Reinsurance News, Insurance Journal, Intelligent Insurer, CTech — plus Parametrix's own post-event research notes, which have themselves become the reference point cited by general business press after major cloud and SaaS outages.
