The short version
Bombora is an intent data provider; 6sense is an ABM platform that includes intent data. That distinction settles most of the comparison. Bombora's Company Surge is the most widely distributed third-party intent dataset in B2B, built from a co-operative of publisher sites that contribute content-consumption data, and it is sold as a data licence you activate in your own CRM, MAP, ad platforms, or in partner platforms, including 6sense itself. 6sense combines its own intent sources with de-anonymised web traffic and CRM history into a predictive buying-stage model, and wraps that in segmentation, scoring, and a display DSP. Choose Bombora when you want transparent, portable intent signals and already own the tools to act on them. Choose 6sense when you want the whole workflow in one place and are prepared to pay for and staff it.

Where they differ in practice
Where the intent comes from
Bombora's data comes from its publisher co-operative: thousands of B2B media and research sites that share content-consumption data under a consent framework. The output is a Company Surge score per topic per week, indicating that an account is consuming more content on a topic than its baseline. It is the same dataset resold inside many platforms, so if you have used intent data in ZoomInfo, Demandbase, or older 6sense tiers, you have probably seen Bombora data.
6sense's intent combines several inputs: its own network of research signals, de-anonymised visits to your website, third-party feeds (6sense has offered Bombora and G2 data through its marketplace), and your CRM's history of what converting accounts looked like. The output is a buying-stage prediction rather than a topic score. That blend is more useful for prioritisation and harder to audit.
Transparency versus prediction
This is the central trade-off. Bombora tells you "Account X surged on 'account-based marketing software' and 'intent data' this week with a score of 87." 6sense tells you "Account X is in the Decision stage." The first is easy to defend to a sales rep and easy to route into a workflow; the second is a better answer if the model is right and an unexplainable one if it is wrong. Reviewers of 6sense who complain about black-box scoring are describing exactly this gap, and reviewers of Bombora who complain that "surge does not equal pipeline" are describing its limit.
What you get beyond intent
Bombora is a data product. It offers Visitor Insights for website de-anonymisation, Audience Solutions for pushing intent audiences to ad platforms, and integrations into most CRMs, MAPs, and ABM tools, but it does not offer contact data, predictive scoring, a DSP, or a sales application. 6sense offers all of those. If you buy Bombora, you are committing to assembling the rest of the stack, which is cheaper and more flexible if you already own the pieces and expensive in ops time if you do not.
Activation
6sense's DSP lets you target accounts in a segment with display ads and see stage progression in the same interface. Bombora's audiences are routed to LinkedIn, to programmatic DSPs, and to execution platforms such as Metadata (our sponsor, disclosed), RollWorks, and Demandbase. The Bombora path is more work to set up and gives you a choice of channels; the 6sense path is easier and confines you to 6sense's inventory and reporting. Teams that care about LinkedIn as a primary channel usually find the Bombora-plus-execution-platform route better, since 6sense's LinkedIn integration is an audience push rather than native execution.
Pricing structure
Bombora licenses are priced by number of topics, delivery method, and integrations, with G2 discussions and reseller notes putting entry contracts in the mid-five figures; large enterprise licences with many topics and multiple destinations run higher. 6sense is a platform fee plus credits, seats, media, and add-ons, starting around $60,000 and commonly reaching $100,000 to $200,000. If you buy Bombora data through 6sense's marketplace, you pay 6sense's markup; for teams that want Bombora specifically, a direct licence is generally cheaper. Our 6sense pricing page has the full breakdown.
Implementation
Bombora setup is a data mapping exercise: choose topics, connect destinations, agree a refresh cadence. Weeks, not quarters. 6sense implementations are 6 to 12 weeks and need an owner afterwards. For a small marketing-ops team, this is often the deciding factor.
Which one fits which team
| If your situation is | Lean toward | Why |
|---|---|---|
| You already own a CRM, MAP, and an ad execution tool | Bombora | Intent is the missing input; everything else exists |
| You have no ABM stack and want one vendor | 6sense | Consolidated workflow |
| Sales demands to see why an account is flagged | Bombora | Topic-level evidence |
| You want a ranked account list without debate | 6sense | Buying-stage model |
| LinkedIn is your primary paid channel | Bombora plus an execution platform | 6sense's display-first DSP is a weaker fit |
| Display advertising at scale across accounts | 6sense | Native DSP with stage reporting |
| Under $50,000 total budget for intent and activation | Bombora plus existing tools | 6sense floor exceeds the budget |
| Leaving 6sense but want to keep intent signals | Bombora | Portable, familiar dataset; see switching checklist |
Using Bombora with or after 6sense
Because Bombora is a data provider, it is not strictly an either/or. Some 6sense customers licence Bombora directly and feed it into 6sense as an additional signal, which is redundant if 6sense's marketplace already includes it and useful if they want the raw topic data in Salesforce as well. More relevant to readers of this site: Bombora is the most common intent source for teams that leave 6sense, because it can be routed into whatever replaced 6sense's activation layer. Our switching checklist covers rebuilding intent audiences on Bombora after export, and the ZoomInfo vs Bombora page covers pairing Bombora with a contact database.

Our verdict
If the question is "which intent data is better," Bombora's is more transparent and more portable, and 6sense's is more predictive and more integrated. If the question is "which should I buy," it depends on whether you want a data feed or a platform. Teams with an existing stack and a modest budget should licence Bombora directly and activate it through tools they already own. Teams that want one vendor to own the whole account-based workflow, and can staff it, should look at 6sense and its like-for-like competitors. Buying 6sense mainly to get intent data is the expensive way to get something Bombora sells on its own.
