6sense
6sense is the enterprise intent data and account-based marketing platform that has defined the ABM infrastructure category since its Series D growth phase, reaching a peak reported valuation of approximately $5.2 billion. Backed by Insight Partners with additional participation from Tiger Global and D1 Capital, 6sense combines B2B buyer intent signals, predictive AI scoring, and multichannel ABM orchestration into a single platform targeting enterprise revenue teams. The platform aggregates intent signals from across the web — including content consumption, keyword research behavior, and third-party publisher networks — and layers predictive models to score accounts by purchase readiness stage. 6sense’s core value proposition is directing sales and marketing resources toward accounts that are actively in-market rather than spraying campaigns at full ICP lists. The platform integrates deeply with Salesforce, Marketo, HubSpot, and major ad platforms, enabling marketing teams to trigger LinkedIn and display ad campaigns against accounts that 6sense scores as late-stage buyers. As of May 2026, 6sense remains the market leader in enterprise intent data, though the valuation premium it commanded in 2021-2022 has compressed alongside the broader B2B SaaS multiple contraction. Bombora and Demandbase are the primary platform-level competitors; G2 Buyer Intent serves the mid-market with more accessible pricing and review-signal-based intent data.
