Best Intent Data Providers for B2B Sales (2026)
The 9 best B2B intent data providers in 2026 - Bombora, 6sense, Demandbase, G2, ZoomInfo and more - compared on signal source, coverage, and what each one can't see.
Why trust this list?
Peter Duffy has spent 20+ years in B2B sales and has used or evaluated most of the tools on this list first-hand. These recommendations are based on real experience - not sponsorships or affiliate deals.
The best intent data providers for B2B sales in 2026 are Bombora, 6sense, Demandbase, G2 Buyer Intent, ZoomInfo, Cognism, TechTarget Priority Engine, Dealfront, and Parsley. Eight of the nine sell third-party intent: signals modeled from research activity happening somewhere other than your own properties. The ninth captures first-party intent from conversations you own. That distinction matters more than any feature comparison, so this guide leads with it.
Third-Party vs First-Party Intent Data
Almost every provider on this list resolves to one of two signal sources, and they answer different questions.
| Third-party intent | First-party intent | |
|---|---|---|
| Where the signal comes from | Publisher co-ops, review sites, ad networks, IP resolution | Your own site, your own conversations, your own outbound |
| What it tells you | This account is researching your category, probably | This named person asked this specific question |
| Granularity | Usually account-level, sometimes person-level | Person-level by construction |
| Freshness | Batched, often weekly | Real time |
| Who owns it | Licensed from a vendor, and your competitors can license it too | Yours exclusively |
| Main weakness | Inference. It is a model's guess about interest | Coverage. It only sees prospects who actually engage |
Third-party intent solves the discovery problem: which of the thousands of accounts you have never spoken to are in-market right now. That is genuinely hard, and Bombora and 6sense are good at it.
First-party intent solves a different problem: of the prospects you have reached, which ones are serious, and what do they actually want. No amount of third-party modeling answers that, because the signal does not exist until the prospect says something.
Most teams eventually run both. The mistake is buying a six-figure third-party contract to answer a question first-party data answers for free.

1. Bombora - The Category's Underlying Layer
Best for: Teams that want the most widely used third-party intent feed
Bombora runs a cooperative of B2B publishers and aggregates content-consumption data across it into Company Surge scores against thousands of topics. It is the closest thing the category has to a standard, and a large share of "intent data" sold by other platforms originates here.
Strengths: The broadest publisher co-op in B2B; topic taxonomy is mature; feeds into most major CRM and ABM platforms.
Limitations: Account-level only, so you still have to guess who at the account to contact. Weekly batching means the signal can be stale by the time a rep acts on it.
2. 6sense - Enterprise ABM and Predictive Scoring
Best for: Enterprise revenue teams with a dedicated RevOps owner
6sense combines co-op intent, anonymous web-traffic resolution, and predictive models into account scores and buying-stage predictions. Its strength is orchestration: it does not just flag intent, it routes and sequences against it.
Strengths: Deep predictive modeling; anonymous visitor resolution; strong ABM orchestration.
Limitations: Enterprise pricing and a multi-month implementation. Value depends on having someone whose job is to run it. For smaller teams, see our guide to 6sense alternatives for SMB sales teams.
3. Demandbase - Intent Plus Advertising
Best for: ABM teams running paid media and sales plays together
Demandbase pairs account intent with an advertising platform, so the same account list drives both ad targeting and sales outreach. For teams where marketing and sales run one motion, that integration is the differentiator.
Strengths: Tight ad-to-sales loop; solid account identification; mature ABM tooling.
Limitations: Most valuable if you are actually running ABM advertising. Enterprise-tier pricing and complexity.
4. G2 Buyer Intent - Late-Stage Signal
Best for: Catching accounts already comparing vendors
G2 sells intent derived from activity on its own review pages: who viewed your category, your profile, and your comparison pages. Because someone reading a head-to-head comparison is far along, G2 signals tend to be later-stage and higher-conviction than co-op topic surges.
Strengths: Genuinely high-intent moments; direct competitive context when someone views a comparison page.
Limitations: Only sees activity on G2. Coverage depends on your category being active there, and on your own review presence.
5. ZoomInfo - Data and Intent in One Contract
Best for: Teams that want contact data and intent from a single vendor
ZoomInfo layers intent signals on top of its contact and company database, so a flagged account arrives with contacts attached. That removes the "now find the right person" step that pure intent feeds leave behind.
Strengths: Contact data and intent in one place; large database; workflow tooling included.
Limitations: Intent is a secondary strength rather than the core product. Pricing scales quickly with seats and credits.
Intent from what prospects actually say
Parsley's presales agent answers your prospects' questions on LinkedIn and email, and captures first-party buying signals from every conversation. Free to start.
Get started free6. Cognism - EMEA-Focused Intent and Contact Data
Best for: Outbound teams selling into Europe
Cognism pairs compliance-focused European contact data with licensed intent signals. For teams where EMEA coverage and GDPR posture matter more than raw US database size, it is a common pick over ZoomInfo.
Strengths: Strong EMEA coverage; compliance-first positioning; phone-verified contact data.
Limitations: Intent is licensed rather than proprietary. Less depth than a dedicated intent platform.
7. TechTarget Priority Engine - Publisher-Owned Signal
Best for: Enterprise technology vendors selling to IT buying committees
TechTarget owns its publisher network rather than aggregating a co-op, so it can see named individuals researching specific technical topics on its properties. For enterprise IT sales, that specificity is hard to replicate.
Strengths: Person-level detail within its network; deep technical topic taxonomy.
Limitations: Only useful if your buyers actually read TechTarget properties. Narrow outside enterprise tech.
8. Dealfront (Leadfeeder) - European Visitor Identification
Best for: Identifying which companies visit your website in Europe
Dealfront, formed from the Leadfeeder and Echobot merger, resolves anonymous website traffic to companies and layers on European company data. It answers a narrower question than the platforms above, and answers it affordably.
Strengths: Accessible pricing; strong European company data; quick to deploy.
Limitations: Company-level, not person-level. Only sees traffic that reaches your site.
9. Parsley - First-Party Conversational Intent
Best for: Knowing what a specific prospect wants before the first call
Parsley is the AI presales agent for LinkedIn and email, powered by Google Gemini. Reps drop a Parsley link on their LinkedIn profile and in outbound emails; the agent answers prospects' questions from the team's own sales docs and captures what each prospect asked as first-party intent data.
It belongs on this list as the first-party entry, not as a replacement for the eight above. Bombora tells you an account is researching your category. Parsley tells you that a named person asked about SSO, your Salesforce integration, and annual pricing - which is a different and later signal.
Strengths: Person-level and real time by construction; signals are yours exclusively; captures intent on outbound surfaces before a prospect reaches your website; buyer intent temperature plus a separate MEDDIC qualification read, both syncing to Attio, HubSpot, Salesforce, Pipedrive, Folk, Close, and Salesflare; usage pricing at 10 cents per conversation with no contract.
Limitations: No account discovery. Parsley cannot tell you which unknown accounts are in-market, because it only sees prospects who engage with a link. If discovery is the problem you are solving, pair it with one of the third-party providers above.
How to Choose
| If your problem is | Start with |
|---|---|
| We don't know which accounts are in-market | Bombora or 6sense |
| We run ABM advertising and sales together | Demandbase |
| We want to catch people comparing vendors | G2 Buyer Intent |
| We need contacts and intent in one contract | ZoomInfo or Cognism |
| We sell enterprise IT | TechTarget |
| We want to see European website visitors | Dealfront |
| We don't know what our prospects actually want | Parsley |
| We have budget for exactly one thing | Whichever of discovery or qualification is actually costing you deals |
The last row is the one most teams get wrong. Third-party intent is expensive because discovery at scale is expensive. If your pipeline problem is that reps walk into calls without knowing what the prospect cares about, that is a qualification problem, and a six-figure discovery contract will not fix it.
Frequently Asked Questions
What is B2B intent data?
Intent data is any signal suggesting a company or person is actively researching a purchase. Third-party intent is modeled from activity on properties you do not own - publisher networks, review sites, ad exchanges - and is usually account-level. First-party intent comes from your own properties and conversations, and is person-level and exclusive to you.
Which intent data provider is the most accurate?
Accuracy depends on which question you are asking. For "is this account in-market", Bombora and 6sense have the largest signal pools and are the usual benchmarks. For "what does this specific prospect want", third-party accuracy is not really the relevant measure - no model infers a question a prospect has not been asked. That is what first-party conversational intent captures directly.
Is first-party intent data better than third-party?
Neither is better in the abstract. Third-party has breadth and finds accounts you have never touched. First-party has precision and tells you what a known prospect actually said. They fail in opposite directions: third-party is a guess about many accounts, first-party is certainty about fewer. Most teams that can afford both run both.
Do I need intent data if I already have a CRM?
A CRM records what already happened with people you already know. Intent data is about what is happening now, often with people who have not contacted you. They complement each other, which is why every provider here syncs into the CRM rather than replacing it. See how buyer intent software fits into a CRM workflow.
How much does B2B intent data cost?
Enterprise third-party platforms typically run annual contracts, and 6sense and Demandbase are commonly quoted in the five-to-six figure range depending on scope. G2 and Dealfront sit lower. First-party tools price differently because there is no data license to fund - Parsley is 10 cents per conversation with no subscription. Check current pricing with each vendor, since it moves.
The Bottom Line
Eight of the nine providers here answer the same question with different data: which accounts might be in-market. If that is your bottleneck, pick on coverage, budget, and how well the vendor integrates with what you already run.
But intent data has a blind spot that no amount of third-party coverage closes. It can tell you an account is researching. It cannot tell you that the VP of Engineering evaluating you needs SAML SSO, has a Q3 deadline, and is also looking at a competitor - unless someone asks her.
Parsley captures exactly that: first-party buyer intent from real conversations on your LinkedIn profile and in your email threads, synced to your CRM before the first call. Start free with 25 conversations, then 10 cents per conversation with no subscription.
