Isidor
Isidor is a frontier enterprise-AI company, founded in 2025 and headquartered in San Francisco with a London presence, building secure, vertically-integrated data pipelines that transform unstructured proprietary enterprise data into training- and evaluation-ready material for foundation models. Its platform spans five capabilities it describes as evaluation (industry-specific and agentic benchmarks), verifiers for generative-AI outputs in critical workflows, reasoning-trace data capture, foundation-model post-training (fine-tuning and alignment on proprietary data), and enterprise-grade security and privacy. Isidor raised an oversubscribed $3.6M pre-seed led by Gradient Ventures, futurepresent, and Seedcamp, with angels from Google DeepMind, Perplexity, and others. The company has no public API or developer surface yet; this profile tracks it as an enrichment lead in 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 Isidor 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 — Isidor scores 6.8/100 (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 Isidor
Each block below is one kind of artifact we hold for Isidor. 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.
