About 6sense

6sense is an account-based marketing and revenue intelligence platform built around predictive AI that identifies anonymous accounts actively researching a category before they engage directly, rather than relying solely on known contact data. It integrates deeply into the broader ABM ecosystem with native connections to Salesforce, HubSpot, Marketo, Salesloft, Outreach, Gong Engage, and major advertising platforms, letting intent signals flow into existing sales and marketing tools without manual export cycles. Unlike Apollo's transparent per-seat pricing, 6sense uses a modular subscription model with custom packages based on AI and intent depth, data credit usage, and orchestration scope, with contracts commonly averaging in the tens of thousands of dollars annually and requiring a sales-led purchase process.
