About 6sense

6sense is an account-based marketing and sales platform for B2B companies. It pulls together signals such as anonymous website visits, third-party research activity and CRM data, matches them to companies, and uses predictive models to score which accounts look ready to buy and which buying stage they are in. Marketers use it to build dynamic account segments, run targeted display ads and orchestrate campaigns, while sales teams get alerts, contact data, a Chrome extension and AI-written emails. It integrates with Salesforce, HubSpot, Outreach and Salesloft and offers a REST API. 6sense is aimed at mid-size and enterprise go-to-market teams; paid plans are sold through sales on annual contracts and are generally expensive, though a limited free tier of its sales-intelligence tool has been offered. The value depends heavily on clean CRM data and the time it takes to configure models and segments.

Best for: Mid-size and enterprise B2B teams running account-based programmes across sales and marketing.

Pros and cons

Why people leave

  • No public pricing; annual contracts through sales
  • Long setup before scores and segments become useful
  • Results depend on the quality of your CRM data
