Ledgebrook is a technology-enabled excess and surplus (E&S) lines managing general agent (MGA) and reinsurance platform founded by Gage Caligaris and headquartered in Massachusetts. It underwrites specialty commercial casualty risk — general liability, professional liability, and cyber — exclusively through wholesale brokers, competing on quoting speed rather than direct-to-consumer distribution. Ledgebrook Re extends the business into delegated-authority reinsurance from London and Dubai.

Ledgebrook publishes no public API, developer portal, or machine-readable API contract. Contract
discovery (OpenAPI, GraphQL, MCP, A2A agent card, /.well-known/*, package registries, GitHub) was
run against every resolvable host and returned no hits — see
well-known/ledgebrook-well-known.yml for the full probe
record. Its broker quoting platform and underwriting workbench are private, credentialed surfaces,
and policy administration runs on Socotra Connected Core; the "open APIs" cited in that partnership
are Socotra's, catalogued under the Socotra provider.
