6sense
6sense is an ABM platform that happens to include a B2B data layer. The core product is intent data: which accounts are researching your category, which keywords they search, which competitor pages they visit. 6sense uses IP-to-company resolution to identify anonymous website visitors and scores them for buying intent. The platform also includes contact data (email, phone) and orchestration tools (advertising, email, Salesforce sync), but most teams buy it for intent signals.
Official site ↗Why it ranks here
6sense ranks 6th because it is expensive, complex, and built for enterprise ABM teams. If your GTM motion is account-based and you need intent signals piped into Salesforce or Marketo, 6sense is a top choice. For transactional or PLG teams, it is overkill.
Where it sits
6sense sits at rank 6 as the top intent-data provider (tied with Bombora). It competes with Demandbase for ABM platform mindshare and wins on predictive scoring and AI features. If you only need intent data (no orchestration), Bombora is simpler and cheaper.
How GTM Engineering teams use it
GTM engineers sync 6sense intent signals (account score, keyword activity, buying stage) into Salesforce custom fields and use them to trigger sequences, prioritize accounts, or route leads. The platform also exports account lists (accounts showing intent for specific keywords) that feed into Clay or advertising campaigns. Common pattern: 6sense identifies intent, Salesloft or Outreach executes outbound, Salesforce tracks pipeline.
In-depth notes
Pricing is enterprise-only with annual contracts. Implementation takes weeks (IP-to-account mapping, keyword setup, Salesforce integration). Intent data accuracy depends on traffic volume; it works well for high-traffic B2B SaaS companies. Be aware: 6sense sells orchestration (ads, email) that competes with your existing stack. Most teams buy it for data and ignore the activation layer. Data freshness is weekly for intent signals, monthly for contact data.
Best for
Enterprise ABM teams, high-velocity B2B SaaS, and account-based advertising (LinkedIn, display).
Avoid if
You run transactional sales, have low website traffic, or need only contact data (Apollo is 10x cheaper).

Setup
Engage 6sense sales for enterprise trial, define target account list (500-1000 companies) and intent keywords (15-20 topics like data warehouse, ETL, cloud migration), then complete technical onboarding with IP-to-account mapping setup and Salesforce integration before intent data flows.
First thing to build
Configure one intent segment (e.g., accounts researching your product category with intent score above 70) in 6sense dashboard, sync to Salesforce as a custom field on Account object, then route high-intent accounts to SDR sequences in Outreach or Salesloft and measure conversion lift over 30 days against baseline (non-intent) accounts.
What actually matters
- Map 6sense intent scores (0-100) to Salesforce Account fields via native integration, then build Salesforce reports to surface accounts crossing score thresholds (70+ for hot, 50-69 for warm) and trigger automated sequences
- Define keyword profiles in 6sense (combination of product category, competitor names, and solution themes) and test on known customer accounts to validate signal accuracy before scaling to full TAM
- Enable account-level analytics in 6sense to track keyword research trends, buying stage movement, and competitor page visits, then export weekly snapshots to Clay or BI tool for longitudinal analysis
- Integrate 6sense Advertising Cloud with LinkedIn Campaign Manager to auto-target high-intent accounts with display ads, but set frequency caps (3 impressions per week max) to avoid ad fatigue
Watch out
6sense intent accuracy degrades below 1000 monthly website visitors; if your site traffic is low or your TAM is under 500 accounts, intent signals will be noisy and sparse, making the platform uneconomical compared to Bombora or Apollo basic intent.
