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.

Sixfold is profiled on the APIs.io network. Tagged areas include Insurance, Underwriting, Artificial Intelligence, Insurtech, and Property and Casualty.

Sixfold’s developer surface includes product news, GitHub presence, engineering blog, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sixfold: open an issue to ask a question, or submit a pull request to add artifacts.
