Feature comparison
Common questions
What is the difference between MarketScale and 6sense?
6sense is a demand-side intelligence platform — it tells you which accounts are researching your category and helps you target them with ads and outbound. MarketScale is a supply-side content platform — it creates the content those accounts find when they search. Together they form a complete B2B marketing system; separately they address different stages.
Should I use MarketScale or 6sense for B2B marketing?
Both, at different budget allocations and maturity stages. 6sense is most effective when you have clear ICP accounts to target with intent-based outreach. MarketScale is most effective for building the organic content moat that creates inbound demand — so 6sense shows you buyers who are already researching terms your MarketScale content ranks for.
The verdict
6sense for intent-based demand activation. MarketScale for the content that creates that demand in the first place.
