6sense
IntentEnterprise ABM platform with buying stage prediction, intent data and sales intelligence
The strongest predictive layer in account based marketing, sold only through an annual enterprise contract, so the evaluation is really about whether your team can operate it.
Best for
Enterprise and upper mid market revenue teams that want predicted buying stage on named accounts wired into Salesforce, Marketo and their ad platforms.
Not great for
Small teams and self serve buyers, since there is no published price, no free plan and no trial to test coverage before a sales process.

6sense, in plain terms
6sense is an enterprise account based marketing and sales intelligence platform, now positioned as an agent powered revenue marketing platform. It sells three things that work together: a data and intelligence layer branded the Signalverse, covering intent signals, B2B buyer data, web deanonymization and account matching; a Revenue Marketing product with audience building, AI email agents, advertising, smart form fill and analytics; and a Sales Intelligence product with account prioritization, list building, company and people search, alerts and a Chrome extension. The predictive model is the reason most buyers evaluate it: accounts are scored and placed in a buying stage such as awareness, consideration or purchase, so teams can work accounts that are already in market rather than a flat list. Their own data pages publish large but internally inconsistent coverage figures, with company profiles quoted between 65M and 75M and buyer profiles quoted between 450M and 750M in different places on the same site. Recent additions include RevvyAI, AI recommended leads and an MCP server that opened in beta in July 2026 so the data can be queried from Claude, ChatGPT and other assistants. Nothing is self serve. The pricing page names three Sales Intelligence bundles and routes all of them to a demo booking, with no free plan or trial advertised.

What reviews praise
- Third party aggregators citing G2 put it at about 4.3 across roughly 1,439 reviews
- Reviewers single out the intent data and predictive scoring as the reason to buy
- A Gartner Peer Insights score of about 4.6 in the account based marketing category is reported by secondary sources
- TrustRadius Top Rated awards in account based marketing, demand generation, intent data and sales intelligence in 2023 and 2024
What reviews flag
- Reviewers report an opaque tier structure and higher than expected costs at renewal
- Add-on fees for data feeds and per seat pricing that scales faster than teams expect are recurring complaints
- Implementation is reported as resource heavy, needing dedicated operations support
- Review platform scores here come from secondary aggregators rather than direct reads of G2, TrustRadius or Gartner, so treat the exact numbers as approximate

6sense does not publish prices. As of August 2026 their pricing page lists three Sales Intelligence bundles, Sales Intelligence with data credits and predictive AI, with data credits only, or with predictive AI only, and every one of them ends in a demo booking rather than a price. Expect an annual contract quoted on the modules, seats and data credits you need, and check their pricing page for any change.
No free plan or free trial is advertised on their pricing page or homepage as of August 2026, where every call to action is a demo booking. Third party articles still describe a free tier with a small monthly credit allowance, but that is not reflected on their current pricing page, so treat it as something to confirm with their sales team rather than a live offer.
It combines intent signals, web deanonymization, account matching and CRM history into a score and a buying stage for each account, such as awareness, consideration or purchase. Marketing uses that to build audiences and target advertising, and sales uses it to prioritize accounts and buyers in the Chrome extension and account pages. It is the capability reviewers most often name as the reason for buying.
Yes. They opened a 6sense MCP server in beta in July 2026, described as making their GTM intelligence available through Claude, ChatGPT and other AI agents. RevvyAI, a conversational assistant inside the Chrome extension and account pages, went to beta for all Revenue Marketing customers in May 2026.
Their own site publishes figures that do not fully agree with each other, quoting 65M to 75M company profiles and B2B buyer profiles between 450M and 750M depending on the page, alongside 111M+ verified business emails and 98M+ direct dial numbers. Treat these as marketing claims and ask for coverage against your own target list before signing.
One of these tools is ours.
