Sixfold
Sixfold is a New York City-headquartered AI company building purpose-built artificial intelligence for insurance underwriting across Property & Casualty and Life & Health lines. Founded by Alex Schmelkin (CEO, previously co-founder of Unqork), Jane Tran (COO), and Brian Moseley (CTO, previously Head of Developer Experience at American Express), Sixfold processes unstructured submissions, automates risk research, produces appetite fit scores, generates cited case narratives, and applies underwriting guidelines consistently across submissions. The platform classifies risk using industry standards (SIC, NAICS, ISO), supports 40+ P&C and Life & Health business lines, and deploys either standalone or via a flexible API into existing underwriting workbench, CRM, and policy administration systems. Customers include Zurich North America, Guardian, Generali GC&C, Skyward Specialty, AXIS, and Mosaic Insurance, collectively representing roughly $265B in gross written premium. The company raised a $30M Series B in January 2026 and operates from offices in New York City and Lloyd's of London. Sixfold is the named provider behind these capabilities and is distinct from Cytora, a separate UK-based insurance AI provider. The platform is sold as enterprise SaaS to insurance carriers; there is no public self-serve developer portal, public API reference, SDKs, or open-source release — API integration is delivered under enterprise engagement.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Sixfold the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Sixfold scores 12.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Sixfold
Each block below is one kind of artifact we hold for Sixfold. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
