# Slintel

> Slintel was a B2B sales and market intelligence platform — company firmographics,
> technographic installs, psychographics and buying-intent scores used by revenue teams
> to prioritize accounts and time outreach. Founded in 2016 and backed by Accel and
> Sequoia, Slintel was acquired by 6sense on 2021-10-05 and folded into the 6sense
> Revenue AI platform. **Slintel no longer operates a developer surface of its own.**
> This file is generated by API Evangelist from the catalog record and from live probes

## Status

- Brand status: acquired, retired into 6sense (announced 2021-10-05)
- `https://slintel.com/` — HTTP 301 on every path to `https://6sense.com/platform/sales`
- `https://www.slintel.com/` — HTTP 403 to automated clients (Cloudflare bot challenge)
- `api.slintel.com`, `app.slintel.com` — DNS records survive, but the AWS load balancers
  they point at no longer resolve; both hosts are unreachable
- No OpenAPI, AsyncAPI, GraphQL SDL, MCP server, agent card, `llms.txt`, `security.txt`
  or any other `/.well-known/` document is served by any Slintel host
- No first-party SDK exists on npm, PyPI, RubyGems, crates.io, Packagist, NuGet or
  pkg.go.dev; there is no `slintel` GitHub organization

## Where the API went

The programmatic surface that carried Slintel's data — company identification,
firmographics, lead scoring and people/contact enrichment — is delivered today through
6sense, and is catalogued in this network under the `6sense` provider.

- [6sense API reference](https://api.6sense.com/docs/): Company, Enrichment and People APIs
- [6sense API overview](https://support.6sense.com/docs/6sense-api-overview): getting started, tokens, credits
- [6sense support](https://support.6sense.com): help center
- [6sense provider profile (API Evangelist)](https://apis.io/provider/6sense/): the full contract set, MCP server and artifacts

Note: 6sense's own API reference does not mention Slintel. The 6sense APIs are published
by 6sense and are scored as 6sense's; they are linked here as the successor surface, not
claimed as Slintel's.
