Slintel

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; this profile reflects that consolidation and captures the surviving public developer surface.

Slintel is profiled on the APIs.io network. Tagged areas include Company, Automation, Sales Intelligence, Market Intelligence, and Data Enrichment.

Slintel’s developer surface includes documentation, API reference, support, and 3 more developer resources.
