Index
Index is the company behind Alloy (alloy.app), an AI-native product-planning and prototyping platform that lets product managers turn any live web app into a pixel-perfect, editable prototype in seconds and ship experiments on real data instead of static mock-ups. Founded by Simon Kubica (ex-Atlassian) and Christian Iacullo (ex-Canva), the company was originally launched as "Index" at index.inc and has since rebranded the product to Alloy. It unifies customer feedback, engineering execution (deep Linear and Jira integration), and design mocks into one workspace of whiteboards, tables, boards, and roadmaps, and exposes an Alloy MCP server so assistants like Claude and Codex can read session design, chat, and code context to accelerate developer handoff. Index is a seed-stage company backed by Bain Capital Ventures. This profile was added to the API Evangelist network as a portfolio-lead stub and enriched from public developer and security surfaces.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Index the way a machine reads it — 4 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 — Index scores 31.3/100 (thin), with a separate agent-readiness read of 12/100 (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 Index
Each block below is one kind of artifact we hold for Index. 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.
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERSecurity Posture 3
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.
