Vendor Review
Bombora Review: Pure-Play Intent Data, Not a Full Platform Replacement
Bombora is different from every other vendor on this list in one important way: it's not trying to be a full ABM platform. It's a pure-play intent data provider, and its Company Surge® data is widely used as an underlying data source by other ABM vendors — sometimes including alongside or even by platforms competing with 6sense. If your complaint with 6sense is specifically about intent signal quality, and you already own an orchestration/advertising platform, Bombora deserves a look as a data-layer swap rather than a full platform swap.
What Bombora does
Bombora aggregates content-consumption data from a cooperative network of B2B publisher sites, then surfaces "surge" signals when a company's research activity around specific topics spikes above its historical baseline. This is a fundamentally different data-collection approach than 6sense's, which blends multiple signal types (including its own web intent capture and third-party data) into a proprietary predictive model. Bombora is narrower in scope but deep in one specific type of signal: topic-level content research intent.
Because Bombora's data is resold and integrated into many other martech platforms (CRMs, ABM suites, and intent tools across the category), it functions almost like category infrastructure. That's a meaningfully different buying decision than a full-suite replacement — you're not replacing 6sense's whole workflow, you're potentially replacing or supplementing the intent data feeding whatever orchestration layer you choose.
Pricing model
Bombora sells its Company Surge data on a subscription basis scaled by data volume and number of topics/segments tracked, sold directly through a custom sales process. It does not publish list pricing. Because it's a data-only product, total cost is typically lower than a full ABM suite license, but you'll need to pair it with an orchestration, scoring, or advertising platform to get equivalent functional coverage to 6sense.
Strengths
What reviewers and buyers consistently praise
- Widely regarded as one of the most established and broadly-integrated intent data sources in B2B martech
- Transparent topic-level surge methodology — easier to explain to skeptical sales teams than an opaque composite score
- Because many platforms already integrate Bombora data, adoption doesn't always require a full platform migration
- Focused product scope means less implementation overhead than a full-suite ABM platform
What reviewers and buyers consistently flag
- No orchestration, advertising, or scoring/workflow layer of its own — you need another platform to act on the signal
- Topic-surge signal alone doesn't replace a predictive model trained on your specific historical deal data
- Company-level (not contact-level) signal, so it still requires a separate data source for people/contact accuracy
- Not a fit for teams wanting a single-vendor, all-in-one replacement for 6sense
Where it beats 6sense
Transparency and interpretability. A topic-surge signal is far easier to explain and audit than a black-box composite intent score — you can literally show a sales rep "this account's research activity around 'ABM software' spiked 300% versus their baseline last week," which is a more defensible story than an unexplained numeric score. If auditable signal is your top complaint with 6sense, Bombora's approach directly addresses it.
Where 6sense still has an edge
6sense's predictive model factors in many more signal types — not just content-consumption surge, but historical deal patterns, firmographic fit, and proprietary web intent capture — combined into a single prioritization score. If you want one number that tells you which accounts to work first without building your own scoring logic on top of raw surge data, 6sense (or another full-suite platform) does more of that work for you out of the box.
Best-fit customer profile
Teams that already have (or are building) their own orchestration and scoring layer and specifically want a best-in-category, well-integrated intent data source to feed it — not teams looking for a single-vendor full replacement of 6sense's entire workflow. Also a strong fit for teams who want interpretable, auditable signal over a composite black-box score.
How to evaluate Bombora specifically
- Confirm your existing CRM/MAP/ABM stack already has (or can build) a native Bombora integration before buying — check the specific integration list, not just "does an integration exist."
- Ask for topic taxonomy detail relevant to your specific market — surge data is only useful if the topic categories map to what your buyers actually research.
- Model out what additional platform (orchestration, scoring, advertising) you'll need to pair Bombora with, and get a combined cost estimate before assuming this is cheaper than 6sense overall.

Bombora vs. the rest of the field
Bombora is the odd one out on this list by design — every other vendor here is a platform you'd log into; Bombora is a data feed you plug into a platform you already have. Compared to ZoomInfo, Bombora is company-level only, with no contact-level data of its own. Compared to 6sense, it's one input into a scoring model rather than a complete scoring model itself. If you're building rather than buying your ABM stack, or you already own an orchestration layer and just want better raw signal, Bombora is a fundamentally different kind of purchase than the other seven vendors reviewed here.
Questions worth asking in a Bombora sales cycle
- Which of your existing martech tools already have a native Bombora integration, and what does that integration actually surface in your workflow today versus what you'd need to build?
- What topic taxonomy coverage exists for your specific industry and product category — ask for real example topics, not a generic pitch deck.
- How does Bombora's publisher cooperative data-collection methodology compare to 6sense's blended signal approach, and does that difference matter for your specific use case?
Scorecard: Bombora vs. 6sense on seven criteria
Bombora tops the scorecard on the two rows that are its whole business, intent breadth and integrations, and scores low on everything a platform does with the data. That is not a weakness; it is the product boundary.
| Criterion | Bombora | 6sense | Why |
|---|---|---|---|
| Intent data breadth | 5 | 5 | Company Surge draws on a publisher data cooperative of thousands of B2B sites; it is the reference intent feed in the category. |
| Predictive account scoring | 2 | 5 | Surge scores rank topic interest but there is no fit model trained on your deals; scoring is your job or your platform's. |
| Advertising execution | 2 | 4 | Bombora syncs audiences to LinkedIn, DSPs, and ABM platforms but does not run media itself. |
| Sales-rep adoption | 3 | 3 | Signal reaches reps only through whatever CRM or platform you route it into. |
| Implementation speed | 4 | 2 | Data delivery is fast; the work is in the integration you route it to. |
| Pricing transparency | 2 | 1 | Quote-only, scaled by topics and volume; G2 discussions put entry licences in the mid five figures. |
| CRM / MAP integrations | 5 | 5 | Pre-built integrations with most CRMs, MAPs, DSPs, and ABM platforms, including 6sense itself. |
| Average | 3.3 | 3.6 | Unweighted mean. Weight the rows that match your actual complaint with 6sense. |
Do not compare the averages. Bombora is a data supplier, and the fair comparison is 'Bombora plus the platform you route it into' versus 6sense. Several 6sense competitors, and 6sense's own data marketplace, resell Bombora, which tells you how central the feed is.
Switching from 6sense to Bombora: what you gain, what you lose
Switching from 6sense to Bombora is really a decision to unbundle: keep or buy an execution platform, and buy the intent feed separately. The gains are control and interpretability; the losses are everything 6sense did for you automatically.
What you gain
- An auditable signal. 'Research on ABM software surged 300% against baseline' is a story a sales rep can check; a composite score is not.
- Portability. The same feed routes to LinkedIn, a DSP, HubSpot, Salesforce, or an ABM platform, so you are not locked to one vendor's inventory.
- A lower data cost than a full suite, with entry licences reported in the mid five figures rather than 6sense's roughly $60,000 floor.
- Choice of topics. You pick the taxonomy that matches your market rather than inheriting a vendor's keyword model.
- The ability to feed the same intent data into several tools at once, including a sales-alerting tool such as Vector.
What you lose
- Predictive account scoring and buying-stage classification. Bombora tells you who is researching, not who fits.
- Advertising execution. You need a DSP, LinkedIn, or an execution platform to act on the audiences.
- 6sense's proprietary web intent capture and contact-level data; Bombora is company-level.
- A single interface and single reporting view across data, ads, and sales.
- Simplicity. Unbundling means integration work and a second (or third) contract to manage.
Before you sign anything, read the switching-from-6sense checklist and the buyout programs page; the contract-exit mechanics matter as much as the feature gap.
Bombora pricing: what is public and what is not
Bombora does not publish prices. Company Surge licences are quoted by the number of intent topics tracked, the volume of accounts or records delivered, and the number of destination integrations. G2 discussions and buyer reports place entry licences in the mid five figures per year, well below a full ABM suite, with larger enterprise feeds priced higher.
Three things affect the quote more than anything else: how many topics you track (start narrow), whether you need weekly or daily refresh, and which integrations you route data to, since some destinations are metered. Also check whether your existing platform already includes Bombora data; HubSpot, several DSPs, and even 6sense's data marketplace resell it, sometimes at a lower effective cost than a direct licence.
Net: Bombora alone is cheaper than 6sense. Bombora plus an execution platform may or may not be, which is why our 6sense vs. Bombora page walks through the combined-cost math.
For the 6sense side of that comparison, our 6sense pricing page compiles the Vendr and G2 contract ranges (roughly $60,000 to $200,000+ per year for the marketing platform).
What reviewers say about Bombora
Bombora holds a mid-4-out-of-5 rating on G2 across a review base in the low hundreds, with themes that are unusually consistent for a data product. Source: Bombora reviews on G2.
Three things reviewers praise
- Signal quality and breadth: the publisher cooperative is described as the most reliable third-party intent source reviewers have used.
- Integration coverage: pre-built connections to most of the marketing and sales stack make it easy to route data.
- Transparency: topic-level surge scores are easier to explain to sales than composite scores from suite vendors.
Three things reviewers complain about
- Noise: surge signals can fire on accounts with no realistic fit, so you need your own filtering or a scoring layer.
- Company-level only: no contact data, so reps still need another source to know who to call.
- Topic taxonomy fit: niche markets sometimes lack topics specific enough to be useful.

Alternatives to Bombora if it is not the right fit
If you want intent data plus something to act on it, or a different kind of signal, these sibling reviews cover the pairings.
- ZoomInfo: if you need contact-level data alongside intent in one product.
- Metadata.io (our sponsor, disclosed): as the execution layer to route Bombora audiences into paid channels; it does not supply intent itself.
- Vector: to deliver Bombora-flagged accounts to reps in Slack rather than in a dashboard.

Our verdict on Bombora as a 6sense alternative
Bombora is the right move if you want to keep or build your own execution stack and just want the best-known intent feed feeding it. It is cheaper than 6sense, more transparent, and more portable. It is the wrong move if you want one vendor to identify, score, and advertise to accounts for you; that is what 6sense charges for, and Bombora does not pretend to do it. Price the whole stack, not the feed, before deciding.
Frequently asked questions about Bombora
Is Bombora a 6sense alternative?
Only for the intent-data layer. Bombora supplies Company Surge topic intent and routes it to your CRM, MAP, DSP, or ABM platform. It does not score fit, run ads, or provide contact data. Pair it with an execution platform to match 6sense's scope.
How much does Bombora cost?
Bombora does not publish prices. G2 discussions place entry licences in the mid five figures per year, scaled by topics tracked, data volume, and destinations. Check whether a platform you already own resells Bombora data.
Does 6sense use Bombora data?
6sense's data marketplace resells third-party intent feeds including Bombora alongside its own proprietary web intent capture. Buying Bombora directly gives you the same feed with more control over where it goes.
Can Bombora data be used for advertising?
Yes. Bombora audiences route to LinkedIn, programmatic DSPs, and ABM execution platforms such as Metadata (our sponsor), RollWorks, and Demandbase. Bombora does not run the media itself.
What is Company Surge?
Bombora's core product: a weekly score showing when an organisation's research on a topic rises above its historical baseline, drawn from a cooperative of B2B publisher sites. Scores are topic-specific and company-level.
