Supercede

Supercede is a London-based reinsurance technology platform. It was founded in 2019 by Ben Rose, Jerad Leigh and Jezen Thomas. Rose and Leigh came from reinsurance broking and underwriting advisory; Thomas led the engineering build. The company was originally called Riskbook. It sits at the reinsurance layer and serves cedents, brokers and reinsurers — preparing treaty submission data, running the placement workflow, and providing analytics on the underlying portfolio.

What it does. The core product is treaty data preparation. A cedent (an insurer that buys reinsurance) uploads raw exposure spreadsheets, loss triangles and bordereaux. Supercede cleans, validates and restructures that data into a submission pack that reinsurers can model from without chasing the broker for missing information. The platform then handles the placement workflow — quote distribution, signings, line capture — and keeps the treaty record in one place for renewal. A 2024 "exhibit-first" view gives underwriters a single snapshot of risk data when they open a submission. From July 2025, Supercede also generates Lloyd's Syndicate Reinsurance Structure (SRS) returns automatically, following its 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. 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 roughly 140 member companies on the platform globally.

Public customer deployments. Ascot Group, a UK specialty (re)insurer, selected Supercede in March 2023 for all outward treaty placements after a pilot at mid-year 2022 renewals. Hollard Insurance Group joined in April 2023 as the first African cedent on the platform, using it for outwards data preparation. Lockton Re signed a long-term agreement and became the first major reinsurance broker to use Supercede's treaty data preparation product across its whole book. Convex was reported by Reinsurance News 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 — this is a technology integration, not a carrier deployment.

Contrast with Tremor. Tremor Technologies tried to solve reinsurance placement as a programmatic auction — buyers and capacity would clear at a single optimised price through a marketplace engine. That approach did not reach commercial scale: in September 2023 the assets were sold to WR Berkley and founder Sean Bourgeois exited, later launching a separate communications platform called Fuse. Supercede takes the opposite approach: keep the negotiated, relationship-driven placement model that London and Bermuda markets actually use, and fix only the data underneath it. Parts of the product are free for brokers and cedents to drive adoption, with revenue weighted toward enterprise seats and reinsurer-side analytics rather than transaction fees.

Contrast with Artificial Labs. Artificial Labs works at the underwriting workstation layer — it handles submission intake, triage and automated following on direct and specialty risks, and is used deep inside Lloyd's syndicate workflow. Supercede works one layer out, on treaty reinsurance rather than individual risk placements. Its focus is the cedent and broker preparing what they bring to reinsurers each renewal. The two tools can sit inside the same carrier: Artificial handles inbound specialty submissions for the underwriting team, Supercede handles 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 releases. No Gartner, Celent or Forrester quadrant for reinsurance technology has covered Supercede as of the April 2026 verification date. Artemis.bm — the main publication for ILS and alternative capital — does not surface Supercede coverage despite the platform's proximity to treaty data.

What it does not do. Supercede is not a facultative placement platform (facultative reinsurance covers individual risks, not whole books). It is 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. It covers the treaty workflow between a cedent, its broker and its reinsurance panel.
