If you want the fastest answer: choose TechTarget Priority Engine for tech buyers, 6sense for predictive revenue teams, and Demandbase for account-based marketing at scale. Intent data helps teams spot buying signals before a form fill, and vendors like Bombora say their data comes from a co-op of more than 5,000 B2B sites [source: Bombora].
TLDR: TechTarget is best when you sell IT, security, cloud, or software products and need named accounts showing real research activity. 6sense is the slicker choice for scoring accounts, predicting stages, and pushing sellers toward the next best action. Demandbase is strong for big ABM programs with ads, account lists, and sales alerts in one place. For example, if 1,000 accounts visit review pages and 7% show “high intent,” your team can focus on 70 hot accounts instead of annoying all 1,000.
Quick scorecard
- TechTarget Priority Engine: Best for real tech purchase intent.
- 6sense: Best for AI scoring and sales timing.
- Demandbase: Best for enterprise ABM and account ads.
- Bombora: Best for topic intent across many B2B sites.
- ZoomInfo Intent: Best if you also need contacts and company data.
1. TechTarget Priority Engine
Best for: B2B tech marketers and sales teams.
TechTarget Priority Engine is very focused. That is its charm. It tracks buyer research across TechTarget’s large network of IT and business tech sites. So if someone reads about endpoint security, cloud backup, or CRM tools, that signal can show up for your team.
The big win is specificity. You are not just getting “Company X is interested in security.” You may see which topics, vendors, and content types people consume. That helps sales avoid lazy openers like, “Just checking in.” Thank goodness.
Watch out: it is strongest in tech. If you sell office furniture or snacks, this is not your magic box.
2. 6sense
Best for: revenue teams that want predictions.
6sense feels like a command center for modern sales and marketing. It pulls in intent, web visits, CRM data, campaign data, and firmographics. Then it scores accounts and places them into buying stages.
The platform is popular because it does more than say, “This account clicked something.” It tries to answer, “Are they ready now?” That is the real question. Sellers do not need more noise. They need a hotter list.
The catch is setup can feel heavy. If your CRM is messy, 6sense will remind you. Loudly. Expect cleanup before the fun begins.
3. Demandbase
Best for: enterprise ABM teams.
Demandbase is built for account-based marketing. Think target account lists, ads, intent, site visits, sales alerts, and reporting. It is good when marketing and sales both agree on named accounts and want to work them together.
Its strength is orchestration. You can build account segments, run ads, spot engaged accounts, and send that activity to sales. It is especially useful when buying groups are large. One person clicking a page may mean little. Ten people from the same account doing research? Now we have a story.
Honestly, it feels like small teams may pay for parts they barely use. Demandbase makes more sense when your ABM motion is mature.
4. Bombora
Best for: broad topic intent.
Bombora is known for “Company Surge” data. In plain English, it shows when a company is reading more than usual about certain topics. That could be “data warehouse,” “payroll software,” or “zero trust security.”
This is great for timing campaigns. If an account suddenly spikes on a topic you care about, sales can act fast. Marketing can also change ads, emails, and content based on that topic.
Weak spot: Bombora is less of a full sales suite by itself. Many teams pair it with CRM, MAP, or sales engagement tools.
5. ZoomInfo Intent
Best for: teams that want intent plus contacts.
ZoomInfo is not only an intent tool. It is also a large B2B database. That matters. Intent without contacts can be annoying. You know an account is active, but who do you call? ZoomInfo tries to solve that in one place.
Sales teams like it because they can move from signal to outreach faster. Find the interested account. Pull contacts. Check titles. Push to sequences. Done.
Downside: data quality can vary by region and role. You still need to verify key contacts before you launch a big push.

Which one should you pick?
- Pick TechTarget if your buyers research tech topics and you want strong purchase signals.
- Pick 6sense if your team needs account scoring, buying stages, and sales prompts.
- Pick Demandbase if ABM is your main growth motion and ads matter.
- Pick Bombora if you want broad topic spikes across many industries.
- Pick ZoomInfo if sales needs names, numbers, emails, and intent in one workflow.
Final verdict
TechTarget Priority Engine wins for deep tech intent. 6sense wins for predicting who may buy next. Demandbase wins for large ABM teams that want ads and account engagement in one system.
The best tool is not the fanciest one. It is the one your sales team will actually use on Monday morning. If reps ignore the alerts, the platform becomes a very expensive dashboard. And nobody needs another one of those.
