Supercede

Supercede is a London-based reinsurance technology platform founded in 2019 by Ben Rose, Jerad Leigh and Jezen Thomas. Rose and Leigh came out of reinsurance broking and underwriting advisory; Thomas led the engineering build. The company (originally Riskbook) sits at the reinsurance-stack layer and works across cedents, brokers and reinsurers — preparing treaty submission data, running the placement workflow, and exposing analytics on the underlying portfolio.

What it does. The core product is treaty data preparation. A cedent's outward reinsurance team uploads raw exposure spreadsheets, loss triangles and bordereaux; Supercede cleanses, validates and restructures the data into a submission pack that reinsurers can model from without chasing the broker for clarifications. The platform then handles the placement workflow — quote distribution, signings, line capture — and keeps the treaty record in one place for renewal. Adjacent features include an "exhibit-first" view launched in 2024 that gives underwriters a consolidated snapshot of risk data on entry, and, from July 2025, automated generation of Lloyd's Syndicate Reinsurance Structure (SRS) returns following Supercede's participation in Cohort 14 of the Lloyd's Lab accelerator.

Funding. Total disclosed funding is approximately $17.5m. A $2.55m seed closed in September 2020. A $15m Series A closed in June 2024, led by Alven with participation from Mundi Ventures and returning investors Outward, Seedcamp, MMC Ventures and AFG Partners. Note: some market speculation has linked Supercede to Mosaic Ventures and Hudson Structured Capital Management; neither appears in the published cap table as of the April 2026 verification date. The Series A announcement cited revenues up "over 500% in the past year" and ~140 member companies on the platform globally.

Public customer deployments. Ascot Group (UK specialty (re)insurer) selected Supercede in March 2023 for all outward treaty placements after a successful pilot at mid-year 2022 renewals. Hollard Insurance Group came on board in April 2023 as the first African cedent using the platform for outwards data preparation. Lockton Re signed a long-term agreement making it the first major reinsurance broker to adopt wholesale usage of Supercede's treaty data preparation product. Convex was named in a Reinsurance News item as having selected Supercede to streamline reinsurance operations. CyberCube partnered with Supercede in August 2025 to pipe structured submission data directly into CyberCube's cyber analytics platform — a technology integration rather than a carrier deployment.

Contrast with Tremor. Tremor Technologies tried to solve the reinsurance-placement problem as a programmatic auction — buyers and capacity would clear at a single optimised price through a marketplace engine. That thesis did not reach commercial escape velocity: in September 2023 the assets were sold to WR Berkley and founder Sean Bourgeois exited, subsequently launching a separate communications platform (Fuse). Supercede's bet is the opposite: keep the negotiated, relationship-driven placement model that the London and Bermuda markets actually run on, and replace only the data substrate underneath it. The product is given away free to parts of the market (brokers and cedents in earlier iterations) to drive network effects, with monetisation weighted toward enterprise seats and reinsurer-side analytics rather than transaction fees.

Contrast with Artificial Labs. Artificial Labs operates at the underwriting-workstation layer — submission intake, triage and algorithmic smart-follow — primarily on the direct and specialty placement side and increasingly deep into Lloyd's syndicate workflow. Supercede operates one layer out, on treaty reinsurance rather than individual risk placements, and its centre of gravity is the cedent and broker preparing what they take to reinsurers each renewal. The two tools can coexist inside the same carrier: Artificial digitises inbound specialty submissions for the underwriting team, Supercede digitises the outward reinsurance programme the same carrier buys to protect its book.

Analyst gap. Coverage is concentrated in London-market trade press (Reinsurance News, Insurance Times, Insurance Business UK, Insurtech Insights, Insurance Edge) and Supercede's own press. No Gartner, Celent or Forrester leader-quadrant placement for reinsurance technology has been published as of the April 2026 verification date, and Artemis.bm — the gold-standard ILS and alternative-capital publication — does not surface Supercede coverage despite the platform's treaty-data adjacency.

What it does not do. Supercede is not a facultative placement platform, not an inward-underwriting workstation, not a claims system, and not a capital-markets intermediary like Ledger Investing. It does not broker risk, does not take principal positions, and does not structure ILS. Its surface is the treaty workflow between a cedent, its broker and its reinsurance panel.
