Why Demandbase, and why now

Demandbase sells the same thing as 6sense - account-based marketing built on intent data - but it owns one piece of plumbing the rival does not lead with: its own ad-buying platform for B2B. That difference decides most purchases. It is also where the intent data comes from, which makes it the privacy question as well.

Three things changed this year. On October 20, 2026 the San Francisco company launched three more AI agents, among them an AEO Agent that "tracks and influences how AI assistants portray brands". Its AI features now draw on a metered credit balance that sits on top of the annual contract. And the price is still not on the website. Demandbase reports 1,000+ customers and 750+ employees, and Gartner named it a Leader for ABM platforms for the sixth year running in October 2026. Everything below was checked in November 2026 against Demandbase's own pages and help centre.

Pricing: quote-only, about $68,600 a year at the median

The pricing page is a form and one promise: "Fill out the form, and we'll customize a pricing plan that works perfectly for you." The structure is described, the numbers are not. There is "a clear platform fee that covers all the essential software and services", then "a flat fee per user". Advertising and Data can be bought on their own as a starting point. The full platform is not split into modules - it is quoted as one plan across your go-to-market teams.

Buyer data fills the gap. Vendr, on a page last updated February 2026, puts the median buyer at $68,591 a year, with deals from $24,000 to $164,037. Those are what customers paid, not list prices.

The contract terms matter more than the headline. Vendr's buyer guide says annual contracts are standard, that multi-year commitments often bring the effective annual price down 15-30%, and that renewals often carry automatic escalators of 3-5% a year. Demandbase's master subscription agreement is not public, so the auto-renewal and notice clause lives in your order form. Read it. Vendr's advice is to open renewal talks 90-120 days before expiry.

The second bill: AI credits and Agentbase

The contract is no longer the whole cost. Demandbase AI Chat "uses 100 AI credits for each completed prompt and response", says the help article updated on November 10, 2026. Credits are granted per period, and "unused credits expire at the end of that period and do not roll over." MCP credits, for plugging outside AI tools in through the Model Context Protocol, are a separate balance. When a balance runs dry, an admin buys another package inside the app and pays through Stripe.

Neither the package prices nor the number of credits a contract includes are published. Do the arithmetic before you sign: ten reps asking AI Chat twenty questions a day burn 20,000 credits a day. Get the allotment and the top-up price in writing.

The agents sit under the Agentbase name, "Demandbase's system of connected AI agents". The tenant settings screen lists more than a dozen, from a Buying Group Setup Agent and an Email Agent to Pipeline Predict descriptions and AI SDR Recommendations, and each has its own off switch. That is the sensible design. An admin can keep anything that emails prospects or writes to the CRM switched off until someone has watched it work. Mojo, a separately branded B2B marketing agent, and the October agents sit alongside them.

The B2B ad platform is the real difference

Demandbase calls its DSP "the only demand side platform (DSP) built specifically for B2B advertising", and on its comparison page against 6sense says rivals "rely on consumer-based DSPs (e.g. Xandr)". Treat both lines as marketing. The practical point survives anyway: you buy display ads against a list of target accounts inside the same tool that scores those accounts, instead of exporting audiences to a separate ad buyer and reconciling the reports afterwards.

The same page claims extra predictive models "deploy in under 24 hours with no added fees" and a #1 rank in G2's Enterprise Grid for Account-Based Advertising. Beyond its own network, audiences go out to LinkedIn, Google Ads, Meta, Microsoft Bing Ads, Reddit and Twitter.

No paid-media budget? Then this is the part you pay for and never use. Ads are the reason to choose Demandbase over 6sense. Without them, the decision comes down to whose intent data your sales team believes.

Where the intent data comes from

The help centre is unusually plain about it: "Demandbase collects intent signals through its B2B demand-side platform (DSP), which provides access to advertising bidstream data across more than one million web publishers." The same ad auctions that power the DSP tell Demandbase which companies are reading about which topics. That is combined with public business registries, B2B content consumption and production, and engagement on your own site, matched against "a vocabulary of more than 650,000 keywords". Bombora, G2, Informa TechTarget and TrustRadius can be added as partner sources.

The caveat is Demandbase's own: "Intent Strength indicates research activity, not confirmed purchase intent." A company reading about data warehouses may be writing a training deck. Reviewers on G2 and TrustRadius make the related complaints again and again - account targeting that is less precise than the scores suggest, and thin person-level contact data once you need someone to call.

Then there is privacy. Under GDPR, Demandbase is your processor for data you upload but a controller for personal data collected by its tag on your website, so your privacy notice has to say so. Separately, Demandbase and InsideView, which it bought in 2021, agreed to a reported $3.7 million settlement of a class action alleging people's personal data was used to sell database subscriptions, according to ClassAction.org.

Integrations, security and leaving

The integration list is long and two-way where it counts. Salesforce syncs bidirectionally, and Microsoft Dynamics and HubSpot CRM are supported. Marketing automation covers Marketo, Eloqua, Pardot, HubSpot and Salesforce Marketing Cloud; sales tools include Gong, Outreach, SalesLoft, LeanData and Slack. Data can be delivered to Snowflake (zero-copy included), BigQuery, Redshift, S3 and Azure Blob. Intent can even be bought alone as a data feed into Salesforce Data Cloud or Adobe Real-Time CDP.

The security paperwork exists but is gated. The trust centre lists ISO/IEC 27001, a SOC 2 Type 2 report and pentest reports for 2024-2026, and the SOC 2 report is shared "under NDA" - procurement signs before it reads.

Leaving is the clause to diary. The security policy says customer data is kept "for up to 13 months following the expiration or termination" of the relationship, unless you ask in writing, in which case it goes within thirty days. Put that letter on your offboarding checklist. How you export your account lists, scores and engagement history on the way out is not documented publicly. Ask before you sign.

Demandbase vs 6sense, RollWorks and HubSpot

Price is not what separates Demandbase from 6sense. Third-party estimates put the two medians within a few thousand dollars of each other, and no reliable source shows either one clearly cheaper. The difference is emphasis: 6sense sells predicted buying stages, Demandbase sells the ad platform and the data plumbing.

Verdict

Review scores are solid rather than glowing: about 4.4/5 on G2 from roughly 2,000 reviews, 4.5 on Gartner Peer Insights from 315 ratings and about 7.9/10 on TrustRadius, at the time of checking in November 2026. The praise is that intent data helps sales time its outreach. The complaint is the work - a steep learning curve and an admin load that needs a named owner.

Buy Demandbase if you run account-based marketing at enterprise scale, live in Salesforce and plan to spend real money on display ads to named accounts. That is where owning the DSP pays off, and where a $68,000 contract is a small slice of the media budget.

Skip it if you are a small team. HubSpot's own ABM tools cover target accounts and account scoring if you already pay for HubSpot, and RollWorks starts around $12,000 a year by third-party estimates. Skip it too if what you want is a forecast of when an account will buy rather than a way to advertise to it. That is the 6sense pitch, and with prices this close, get both quotes. Whichever you sign, get the AI credit allotment, the top-up price and the renewal escalator in writing.
