6sense

Overview

6sense (6sense.com, founded 2013, San Francisco) is the platform most people mean when they say "ABM." Its current framing is 6sense Revenue AI: a sales-and-marketing platform built on three proprietary layers — Signalverse (a global B2B signal network ingesting behavioral, firmographic, and technographic signals from a large B2B publishing network), the 6signal Company Graph (matching anonymous IP-level research activity to named companies), and the 6AI predictive engine (scoring accounts into buying stages: Target, Awareness, Consideration, Decision, Purchase).

The commercial thesis is the dark funnel: most B2B research happens anonymously before anyone fills out a form. 6sense's pitch is that its Company Graph sees that anonymous activity, tells you which accounts are in-market and at what buying stage, and then orchestrates engagement — ads, email, web personalization, and sales outreach — against those accounts. Marketing gets Revenue Marketing (audience building, account-based advertising, smart form fill, web deanonymization); sales gets Sales Intelligence (contact and company data, Chrome extension, Sales Copilot AI summaries and recommended actions, list building, data credits for exports).

The AI layer has grown quickly: Sales Copilot for in-CRM guidance, AI Email Agents ("Conversational Email") that personalize, respond, and book meetings autonomously, and an AI Writer in beta. For RevOps, Intelligent Workflows turn signals into automated cross-channel plays, and Dynamic Segments sync to ad platforms and CRMs.

Key features

• Account-level intent data — aggregates first- and third-party research behavior to reveal which accounts are actively researching relevant topics, even anonymously.
• Predictive buying stages — AI assigns each account a stage (Target → Purchase) plus a fit/in-market score (6QAs), driving who sales calls and when.
• Web deanonymization — the Company Graph matches anonymous site traffic to companies, exposing dark-funnel demand.
• Sales Intelligence & Chrome extension — contact/company data, technographics, psychographics, persona maps, and intent surfaced on LinkedIn or any website.
• Audience Builder & Dynamic Segments — visual segmentation that powers activation across ads, email, web, and sales.
• Intelligent Workflows — drag-and-drop orchestration across channels triggered by intent and stage changes.
• Account-based advertising — native and connected execution across display, video, LinkedIn, and Google, driven by 6sense segments.
• AI Email Agents — conversational email that personalizes at scale and books meetings.
• Smart Form Fill — real-time form shortening and enrichment using 6sense data.
• Data credits — used to unlock and export emails, phone numbers, and enriched records; volumes are not published.
• Integrations — Salesforce, HubSpot, Dynamics 365, Marketo, Outreach, Salesloft, Drift, Qualified, LinkedIn/Google Ads, Slack, Clay, plus Data APIs and a website tag.

Pricing

6sense does not publish any pricing. Its Sales Intelligence pricing page presents bundles — Sales Intelligence, + Data Credits, + Predictive AI, or the full combination — and every one of them is quote only; you must contact sales. There is no self-serve checkout, no published seat counts, and no published credit volumes or per-credit pricing.

Public benchmarks from third parties, since the vendor won't give numbers:

• Vendr procurement data (385 purchases): median annual contract of roughly $62,000, ranging from about $11,400 to $177,000, with buyers saving ~17% on average versus list; deployment bands run ~$50K–$120K for small deployments (2,000–5,000 tracked accounts) up to $250K–$400K+ for enterprise, with implementation quoted separately (commonly $10K–$50K).
• AWS Marketplace listing (an illustration of enterprise scale, not an entry price): 6sense Revenue AI with a 5-license core at $100,000 for 24 months (up to 25% savings on multi-year), with advertising media negotiated separately.
• Cost concentrates in data credits, seat expansion, and advertising tiers; onboarding and ad media are typically billed on top of platform fees.

Also important: 6sense discontinued its free plan on August 12, 2026 (previously 50 data credits/month with contact/company search, alerts, list management, and the Chrome extension). Existing free-only accounts lost access and new free registrations are closed. There is no free trial. Evaluating the product means sitting through a demo-led sales cycle.

Who it's for

6sense fits mid-market and enterprise B2B teams with a five-figure (often six-figure) annual ABM budget, dedicated marketing-ops/RevOps capacity to run it, and an audience of technology buyers. It's best when the core problem is not knowing which accounts are in-market. It's a poor fit for startups and small teams (cost, complexity, no free tier), for non-tech audiences (signal coverage), and for buyers who need individual-level targeting or transparent pricing.

Alternatives

• Demandbase — the closest competitor; similar cost profile and the same learning-curve complaints from buyers.
• Bombora — intent data only; a cheaper way to get company-level intent without the full platform.
• ZoomInfo Sales — stronger contact database with intent features; better for individual-level prospecting.
• Terminus / Demand Science — ABM alternatives with different data and packaging.
• Leadfeeder — lightweight, affordable website-visitor identification for teams not ready for enterprise ABM.
• Clay — flexible GTM orchestration that can pull third-party intent and build ABM workflows at a fraction of the cost.
