6sense

Market leader in AI-powered B2B account engagement and buyer intent data, competing at the top tier alongside Demandbase and ZoomInfo

6sense is a leading AI-driven account engagement platform designed for B2B revenue teams. Founded in 2013 and headquartered in San Francisco, the company helps organizations identify anonymous buyers who are actively researching solutions, predict which accounts are most likely to convert, and orchestrate personalized outreach across multiple channels. By aggregating billions of intent signals from across the web and combining them with first-party data, 6sense enables go-to-market teams to prioritize the right accounts at the right time with the right message. 6sense's platform sits at the intersection of account-based marketing (ABM), sales intelligence, and revenue operations. Its core capabilities include buyer intent data, predictive AI scoring, audience segmentation, and multi-channel campaign activation. The platform integrates deeply with CRM systems like Salesforce, marketing automation tools like Marketo and HubSpot, and advertising platforms, making it a central orchestration layer for modern B2B revenue stacks. The company has grown rapidly through a combination of organic product development and strategic acquisitions, including Slintel (technographic and intent data) and Saleswhale (AI-powered email engagement). 6sense competes directly with Demandbase, Bombora, TechTarget, and ZoomInfo in the B2B intent and ABM space. It has established itself as a market leader, consistently recognized in analyst reports from Forrester and G2, and counts hundreds of enterprise and mid-market B2B companies among its customers. With over $200M in total funding and a valuation that reached unicorn status, 6sense is one of the most well-capitalized and strategically positioned players in the B2B AdTech and revenue intelligence ecosystem.
