6sense

6sense is an enterprise revenue intelligence platform focused on identifying anonymous buying behavior and predicting which accounts are most likely to purchase. It's the market leader in intent data and account-based marketing (ABM) orchestration.

The platform's core capability is 'dark funnel' visibility — identifying the research and buying signals that happen before a prospect ever fills out a form or talks to sales. 6sense tracks anonymous web visits, content consumption, keyword research, and third-party review site activity to build a picture of which accounts are actively researching solutions like yours.

Accounts are scored and segmented into buying stages (awareness, consideration, decision, purchase) using predictive AI models. Sales teams get alerts when target accounts move into active buying stages, enabling timely outreach. Marketing teams can orchestrate targeted advertising campaigns to accounts showing intent signals.

The platform integrates with major CRMs, marketing automation platforms, and sales engagement tools to activate intent data across your existing workflow. This means sales reps see buying signals directly in Salesforce, and marketing can trigger personalized campaigns in Marketo based on account behavior.

Pricing is enterprise-level, typically $2,000-5,000+/month depending on features, data volume, and company size. Implementation requires dedicated resources and typically takes 2-4 months. The platform delivers the most value for B2B organizations with deal sizes above $50K, long sales cycles, and established marketing operations.

For smaller teams or those with shorter sales cycles, the investment may not be justified. Clearbit Reveal offers basic website visitor identification at a lower price point, and tools like Bombora provide intent data without the full ABM platform.
