Ineffable
Ineffable Intelligence is an AI research lab founded by David Silver aiming to make "first contact with superintelligence." The company is building a "superlearner" that discovers knowledge from its own experience using reinforcement learning, without relying on human data, with the goal of rediscovering and transcending human inventions such as language, science, mathematics and technology. Backed by Bond Capital and Index Ventures, Ineffable is an early-stage research lab: at this time it publishes a mission/beliefs site, a founder blog note, and open roles, but no public API, developer portal, SDKs, or machine-readable specifications. This profile captures the company's public identity and domain-security posture for the API Evangelist network.
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 Ineffable the way a machine reads it — 1 machine-readable artifact, 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 — Ineffable scores 11.4/100 (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 Ineffable
Each block below is one kind of artifact we hold for Ineffable. 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 1
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.
