hyperexponential
hyperexponential (hx) is a London-based insurtech that builds the #1 pricing and underwriting decision platform for commercial property & casualty (P&C) insurance. Its platform - spanning the Hyperoperator agentic assistant, a no-code Workflow Builder, Calculation Engines, and Portfolio Intelligence - lets actuaries and underwriters build, deploy, and iterate pricing models and underwriting workflows without heavy engineering. Carriers use hx to automate submission triage, risk assessment, renewals, portfolio monitoring, and regulatory compliance, with top global carriers running $75bn+ in annual commercial P&C premium on the platform. hyperexponential is backed by a16z and Battery Ventures. This API Evangelist profile tracks the company's public developer, security, and compliance surface; hx does not publish a public developer portal or OpenAPI, so this repo is enriched from identity, trust-center, and domain-security signals.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles hyperexponential 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 — hyperexponential scores 19.1/100 (emerging), 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 hyperexponential
Each block below is one kind of artifact we hold for hyperexponential. 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.
