Ark.com
Ark.com was a people search engine founded in San Francisco in March 2012 by Patrick Riley and Yiming Liu, and part of Y Combinator's Winter 2012 batch. Ark indexed over a billion public social network profiles — aggregating "ghost profiles" from Facebook, LinkedIn, AngelList and other networks — and let users search across them with filters such as hometown, current city, high school, college, employer and interests, to reconnect with classmates and acquaintances or find new business contacts. The company raised a $4.2M seed round in April 2012 from Andreessen Horowitz, Greylock Partners and SV Angel, and reached the finals of TechCrunch Disrupt NYC 2012. Ark is no longer operating: Y Combinator lists the company as Inactive and PitchBook lists it as Out of Business. As of a July 2026 probe the ark.com domain no longer serves the company — it redirects to www.ark-invest.com, the unrelated ARK Investment Management site — and no api., developer. or docs. subdomain resolves. Ark never published a public API, developer portal or SDKs, so there is no API surface to catalog. Retained as a historical a16z portfolio record only.
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.
Ark.com is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Ark.com scores 5.0/100 (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.

Properties that don't map to a standard resource type
Ark.com is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
← All providers · Data indexed from github.com/api-evangelist/arkcom · machine-readable index on apis.io
This is an independent, third-party profile of Ark.com, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
