6sense vs Demandbase: Features, Pricing, Ratings (2026)

Either platform names the accounts. To reach the people inside them, the contact finder turns a name and a company into a verified work email inside a free Cleanlist AI workspace.

6sense vs Demandbase at a glance

Sources: 6sense.com and demandbase.com (home, pricing, product, about and comparison pages), trymojo.ai, Vendr, G2, Gartner Peer Insights and TrustRadius, all read November 10, 2026. Our full write-ups are the 6sense review and the Demandbase review.

Is Demandbase similar to 6sense?

Yes. Each publishes a comparison page against the other, and Gartner Peer Insights lists each as the other's top alternative. Both identify the companies behind anonymous research, score which accounts are in market, run ads to target accounts, give sellers account insights and contact data, and write the results back to the CRM. Both quote every deal. Both say Gartner named them Leaders in its Magic Quadrant for Account-Based Marketing Platforms dated October 7, 2026, each for the sixth year in a row, and both say Forrester named them Leaders in its Q1 2026 Wave for B2B revenue marketing platforms. Both now sell AI agents and connect to AI tools through MCP.

The differences are in emphasis. 6sense puts its weight on predicting buying stages and on sales intelligence for reps. Demandbase puts its weight on account-based advertising and on letting teams shape account lists, stages and buying groups to their own process.

Intent data and account identification

6sense gets most of its keyword intent from its own publisher network, where a web tag records reading behavior, and adds ad data from its own demand side platform, licensed networks, review sites such as G2 and TrustRadius, and Bombora, with 12 Bombora topics included. Teams add unlimited custom keywords, live within 24 hours. Website visits are matched to companies mainly by IP address.

Demandbase builds intent from bidstream keywords and curated content, lists 865K+ intent keywords, and matches website visits to companies across 3.7B+ IP addresses. It says it favors match accuracy over inflated match rates.

Both identify the company behind a visit. Neither publishes a match rate or an intent accuracy rate that an outsider can check, so the only fair comparison is a test on your own traffic and your own closed deals (see the test below).

Predictive scoring and buying stages

6sense trains a model on your own closed-won history, back-tests it monthly, and predicts each account's buying stage. An account that fits your profile and reaches the Decision or Purchase stage becomes a 6sense Qualified Account (6QA), one flag that combines fit and stage. Explanations and confidence scores for those predictions were announced for open beta in November 2026.

Demandbase prioritizes accounts on fit, engagement and intent, and lets teams define their own account stages and buying groups, which reviewers single out as a strength. It says its predictive models deploy in under 24 hours with no added fees.

If your team wants one predicted stage per account that reps can act on, 6sense is built around that. If your team wants to define the stages itself, that flexibility is what Demandbase's reviewers credit.

Advertising

Demandbase calls itself the only demand side platform built specifically for B2B advertising, and runs ads across display, video, CTV, social and web, aimed at accounts and buying groups. Demandbase says it ranks #1 in G2's Enterprise Grid for account-based advertising.

6sense runs account-based ads from its Revenue Marketing package, and in November 2026 announced an OpenX integration that extends reach to more than 100 recommended ad destinations, plus segment sync to DV360 next to Google Ads.

If ads are your main channel to target accounts, Demandbase is the one built around them. If ads are one channel among several, both cover it.

Sales intelligence and contact data

6sense sells Sales Intelligence as its own package: in-market accounts ranked from cold to hot, buying stages, recommended contacts, company and contact search across 370M+ buyer profiles, alerts in Slack or email, a Chrome extension and RevvyAI briefs. It lists 111M+ verified business emails and 98M+ direct dials.

Demandbase sells Sales inside its platform: in-market accounts, buying group members and next steps in the seller's tools. It lists 200M+ B2B contacts.

Reviewers of both raise contact data. TrustRadius's summaries list data accuracy, including contact information, among 6sense's cons, and thin person-level contact data first among Demandbase's. Neither vendor publishes a contact accuracy rate, and we have not tested either one. Our own testing shows why it is worth checking: in our 1,000-lead test in March 2026, two contact databases differed widely on the same list, with ZoomInfo matching a work email for 84% of leads and a mobile number for 67%, against 78% and 41% for Apollo.

Pricing and contracts

Vendr pages updated February 2026; all figures read November 10, 2026.

The medians sit close together, and the ranges overlap almost entirely, so your quote will depend on accounts, users, modules and term more than on the brand. For the line items to ask about, see our 6sense pricing guide and the pricing section of the Demandbase review.

What each vendor says about the other

Both companies publish a comparison page about the other. Read them as sales material: neither shows a test.

Demandbase says (demandbase.com/why-demandbase/6sense, read November 10, 2026):

• It is the only DSP built specifically for B2B, while 6sense relies on DSPs built for consumer advertising, naming Xandr.
• Customers rate it higher than 6sense on G2 across categories such as account-based advertising (8.2 vs 7.6), lead quality (8.3 vs 6.9) and predictive scoring (8.3 vs 7.6). The page gives no dates or sample sizes for these scores.
• Its native intent source sees "over 2 trillion signals per month," and its predictive models deploy in under 24 hours.

6sense says (6sense.com, comparison page published March 4, 2026):

• It processes more than a trillion signals a day, and its AI models have trained on B2B buying patterns for over a decade.
• It captures unlimited intent keywords, where Demandbase works by topic with broad keyword expansion.
• It identifies more website visitors than tools that rely on IP alone, and a typical enterprise implementation takes 4 to 6 weeks.
• Demandbase's Trade Desk integration reaches only part of the available ad inventory.

Test both before you sign

A demo shows the accounts the vendor picks. Your own accounts show what you will get. Here is a 30-account test you can run during the evaluation, with what each step costs.

1. Pick 30 accounts you know well: 10 you won last year, 10 you lost and 10 that never engaged.
2. Ask each vendor to show what its platform saw at those accounts in the 90 days before each deal opened. A useful model ranks the won accounts high and the silent ones low.
3. Compare website identification on the same week of your own traffic, with both tags running.
4. Check the contacts. Take 20 contacts each platform returns for your target accounts and run them through the email verifier, which checks 2 addresses free every 30 days per IP, or at half a credit each inside a Cleanlist AI workspace.
5. Fill the gaps. For buyers either platform misses, the contact finder looks each person up across 25+ data providers in sequence and verifies the email before you see it, at 1 credit per verified email and 10 per phone number, with nothing charged for a miss.
6. Get both quotes for the same scope: the same accounts, users, modules and term, with the renewal notice date and any cap on renewal increases in writing.

What the contact steps cost: nothing on the free checks. A new Cleanlist AI workspace starts with a 14-day Pro trial with up to 3 seats and 250 credits, plus 100 more for a work email signup, and a card is required. Verifying 40 contacts and finding 30 more, with phone numbers for 10 of them, uses at most 150 credits.

If neither fits

On G2 (read November 10, 2026), the other products shown next to these two are GTM Workspace from ZoomInfo at 4.5 out of 5 from 9,234 reviews, AdRoll ABM (formerly RollWorks) at 4.3 from 661, and Bombora, an intent data provider, at 4.4 from 157. Our ABM platform alternatives study and intent data providers comparison cover the wider field.

Cleanlist AI (our product)

Disclosure. We make Cleanlist AI. Its 98% verified email and 85% direct dial figures come from our own 500-lead benchmark, which named no other vendor.

Cleanlist AI is one platform with AI agents that find buyers, get verified emails and phone numbers from 25+ providers through waterfall enrichment and send the sequences. Plans are published: Starter is $49 and Pro $89 a seat a month, with HubSpot and Salesforce sync on Pro. It sells no intent data and runs no ads, so it fits teams whose gap is the people at accounts they have already chosen, alongside 6sense, Demandbase or neither.

Frequently asked questions

Who are 6sense's main competitors?

Demandbase above all. Gartner Peer Insights lists Demandbase, DemandScience and ZoomInfo as 6sense's top alternatives in the ABM platform market, and G2 shows Demandbase One, GTM Workspace from ZoomInfo, Bombora and AdRoll ABM next to it (both read November 10, 2026).

Is 6sense going public?

There is no sign of it. On November 10, 2026, SEC EDGAR listed only three Form D notices of private offerings for 6Sense Insights, Inc., the latest dated February 4, 2022, and no S-1 registration. 6sense's about page shows investors such as Insight Partners, and its newsroom announced no IPO.

Which is cheaper, 6sense or Demandbase?

On Vendr's buyer data, 6sense's median is lower ($62,220 against $68,591 a year), and its range starts lower too ($11,191 against $24,000). The ranges overlap, so the cheaper one is whichever quotes your scope for less. Ask both for the same accounts, users and term.

Which is faster to implement?

G2 reviewers report about 2 months for Demandbase, 2 months for 6sense Sales Intelligence and 3 months for 6sense Revenue Marketing. The vendors' own claims are shorter: 6sense says 4 to 6 weeks for a typical enterprise rollout, and Demandbase says its predictive models deploy in under 24 hours.

Can a small team use 6sense or Demandbase?

It can, though neither is built for one. Buyers report contracts in the tens of thousands of dollars a year for both, and both need someone to run the platform. A small team that knows its accounts usually gets more from a contact data tool and a sequencer, and adds an ABM platform once it runs a program across thousands of accounts.
