6sense

6sense is an enterprise B2B go-to-market intelligence platform that unifies first-party intent data, AI predictive account scoring and conversational AI in a single system for teams selling into named accounts. It serves mid-market and enterprise B2B technology, SaaS and services companies whose sales and marketing teams need to identify which accounts are researching a purchase before those accounts identify themselves. 6sense was founded in 2013 and competes in the ABM and revenue intelligence category alongside Demandbase. It was named a Leader in The Forrester Wave: Revenue Marketing Platforms for B2B, Q1 2026. The core differentiator is intent data depth. Rather than relying primarily on third-party intent aggregators, 6sense operates a proprietary first-party intent network it calls the Signalverse. The vendor describes it as 13 years of intent data combined with customer first-party data from CRM, marketing automation, web and product, plus third-party signals such as job changes and funding. The platform layers per-customer predictive models on top to determine buying-stage likelihood at account level, and the vendor positions these as explainable rather than black-box scores. RevvyAI is the conversational layer, giving revenue teams intelligence grounded in account signals, intent and activity. 6sense launched an MCP server on 13 July 2026, which is how the platform delivers intelligence to external AI agents. The vendor publishes connection instructions for Claude, Copilot and ChatGPT, and states that any MCP-compatible agent can query it. The server is in beta and available to Revenue Marketing license holders. Typical uses are asking which keywords are driving research activity among target accounts and which target accounts have visited the site or gone quiet. Alongside MCP, 6sense integrates natively with Salesforce, HubSpot, Marketo and Microsoft Dynamics for bidirectional CRM and marketing automation sync, supports sales engagement platforms including Salesloft and Gong, and offers a Chrome extension that surfaces account intelligence inside seller workflows. Pricing is quote-only across every module with no public dollar figures. The Sales Intelligence pricing page publishes three bundles, Sales Intelligence with Data Credits and Predictive AI, Sales Intelligence with Data Credits, and Sales Intelligence with Predictive AI, and every one routes to a demo booking rather than a rate. Data credits are the consumption mechanism and are used to unlock and export emails, phone numbers and enriched contact and company records. The full platform adds intent data, ABM display advertising, AI email and RevvyAI, all on the same quote-only basis, so total cost cannot be established before a sales conversation. 6sense is not a fit for SMB B2B teams, teams without a dedicated marketing operations function, or organizations that have not yet built clean CRM data. Reliable scoring depends on accurate CRM data and on configuration of segments, scoring models and intent keywords before the platform produces actionable output, which makes it a poor choice for teams needing a fast, lightweight ABM motion. Teams primarily seeking contact data and prospecting sequences rather than an ABM intelligence platform should look at Apollo.io ($49/mo billed annually) instead. Current state Q3 2026: 6sense has repositioned as intelligence for agentic GTM, leading with the Signalverse intent network and with MCP and APIs as distribution channels for delivering intelligence into other tools and AI agents. Security certifications published on the 6sense trust page cover SOC 2 Type 2 across all five Trust Service Criteria, ISO 27001 and ISO 42001 (both certified through Schellman with annual third-party audits), GDPR and CCPA. ISO 42001 for AI Management Systems remains uncommon among ABM platforms.
