description: 'Slintel is a B2B sales and market intelligence platform that mines buyer and technographic signals — company
  firmographics, technology installs, psychographics, and buying-intent scores — to help revenue teams prioritize accounts
  and time outreach. Founded in 2016 and backed by Accel and Sequoia, Slintel was acquired by 6sense in 2021 and its data
  and API services are now consolidated into the 6sense Revenue AI platform. Slintel''s programmatic surface (company identification,
  firmographics, lead scoring, and enrichment) is delivered through the 6sense API Portal rather than a standalone Slintel
  developer portal. As of a 2026-08-14 probe pass, Slintel operates no developer surface of its own: slintel.com redirects
  every path into 6sense.com, the historical api.slintel.com and app.slintel.com hosts are decommissioned, no /.well-known/
  document or machine-readable spec is served, and no first-party SDK exists in any public package registry. The successor
  APIs are catalogued under the 6sense provider.'

x-attribution:
  note: The DeveloperPortal, Documentation, APIReference and Support pointers carried by this record until 2026-08-14 all
    resolved to 6sense hosts (api.6sense.com, support.6sense.com). They have been removed. 6sense's own API reference does
    not mention Slintel anywhere, and no Slintel-branded operation exists in it, so those pages document 6sense's API rather
    than a surviving Slintel developer surface — keeping them would credit Slintel with a developer program it does not operate.
    The successor surface is recorded in lifecycle/slintel-lifecycle.yml and is catalogued in full under the `6sense` provider.

  detail: 'Slintel was absorbed into 6sense (announced 2021-10-05) and its own surface is gone: slintel.com answers a blanket
    HTTP 301 to 6sense.com/platform/sales on every path including /openapi.json and every /.well-known/ path, while api.slintel.com
    and app.slintel.com still carry DNS CNAMEs to AWS load balancers that no longer resolve.'
