description: '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.'
