Lloyd's Lab Accelerator · Cohort 17
Lloyd's is a market, not a company — markets need shared infrastructure, and that's what DeIn builds. Execute once. Share once. Settle once. Start with your next parametric launch — without replacing your existing systems.
The Problem
Japan faces the world's most frequent and severe earthquake peril. A massive protection gap remains — and Lloyd's market fragmentation makes launching even a parametric product operationally hard.

Design Principles
Not features — the choices that make DeIn fundamentally different from any platform retrofitted from legacy systems.
Pricing curves, contract terms and underwriting rules live as versioned code, not PDFs and spreadsheets. Every change is traceable.
Why it matters — Cedants, syndicates and regulators read the same source of truth — no version conflicts between sales decks and operations manuals.
Every event-to-payout path is simulatable before the loss and verifiable after. Logic is exposed, not hidden inside black-box claims.
Why it matters — Counterparty trust is built before the catastrophe, not litigated after. Settlement disputes collapse from months to hours.
Pricing, policy logic, trigger and payout execution run on one coherent stack — not bolted together from separate vendor systems.
Why it matters — What gets quoted is exactly what gets executed. No drift between sales price, treaty wording, capacity allocation and payout calculation.
Roadmap
The same rail that automates Lloyd's back-office today scales to multi-peril and alternative capital tomorrow.
