6sense Insights is a B2B revenue AI platform that identifies in-market accounts from anonymous buying signals and orchestrates marketing and sales against them. Its Signalverse intent graph, Master Company Database of roughly 76 million company accounts and predictive models power account-based marketing, advertising, AI email agents and sales intelligence. For developers, 6sense exposes six HTTP data APIs across three hosts — Company Identification, Company Firmographics, Lead Scoring, Lead Scoring and Firmographics, People Enrichment and People Search — plus the acquired AI Email (Saleswhale) API with a signed webhook surface, and a hosted remote MCP server at api.6sense.com/mcp for agent access. Access is token-based and metered against contract-year credit pools rather than list-priced plans.
