Bombora vs 6sense: Which Intent Data Provider Should You Buy?

The short version

Bombora is a data vendor and 6sense is a platform, and that single difference decides most Bombora vs 6sense evaluations. Bombora sells the widest third-party B2B intent feed on the market, Company Surge, and delivers it into whatever stack you already own. 6sense sells intent as one component of a revenue platform that also does predictive account scoring, first-party visitor identification, contact data, advertising and a sales workspace. If you already have somewhere to activate intent, Bombora is the cheaper and more flexible buy. If you do not, 6sense saves you from assembling that stack yourself, at a price that reflects it.

The two are not mutually exclusive. 6sense has a Bombora partnership and can ingest Company Surge data, and a common enterprise pattern is Bombora as the broad topic feed inside 6sense as the scoring and activation layer. The head-to-head question is really "do I need the platform," not "which signal is better."

Bombora vs 6sense at a glance

Everything in the table is taken from the vendors' own product and pricing pages and their G2 listings, linked in the sources. Where a vendor does not publish a number, the cell says so rather than guessing.

Where the signal comes from

Bombora: one source, done thoroughly

Bombora's entire product is Company Surge. It operates a data co-op of B2B publisher and vendor sites that agree to share consented, de-identified content-consumption data. Bombora maps each page to topics in its taxonomy, resolves the reader to a company, and each week compares the company's activity on each topic against that company's own baseline. A statistically significant increase produces a surge score. The output is a list of accounts, topics and scores, updated weekly.

The strength of this model is that it is broad, consented and neutral. Bombora does not compete with the platforms it delivers into, which is why 6sense, Demandbase, ZoomInfo, Warmly and RollWorks all resell or integrate it. The weakness is that it is account-level topic data and nothing else. You do not get names, you do not get a fit score, and you do not get a prediction of where the account is in its journey. You get "this company is reading more than usual about these topics."

6sense: several sources, blended into a prediction

6sense builds its intent signal from at least three places. First, a proprietary crawl of web content that it classifies by keyword and resolves to accounts through its own identity graph. Second, first-party data from your own website, de-anonymized to the account level via the 6sense tag. Third, partner data, including Bombora Company Surge where contracted. It then runs those inputs through a predictive model trained on your historical opportunities to assign each account a buying stage and a fit score.

The strength is that the output is closer to an answer. Instead of "this account surged on three topics," you get "this account is in Decision stage for your product line and here are the contacts." The weakness is that the model is opaque, its quality depends on the volume and cleanliness of your CRM history, and the whole thing lives inside 6sense. You cannot easily take the 6sense buying-stage score and push it into a competitor's platform.

Which signal is better?

Neither, in the abstract. Bombora's topic surge is the more transparent signal: you can see exactly which topics fired and reason about them. 6sense's buying stage is the more actionable signal when it is right, and harder to sanity-check when it is wrong. Teams with strong ops staff tend to prefer Bombora's raw feed because they can build their own scoring; teams without that staff tend to prefer 6sense because the scoring is done for them.

What you can do with it

Bombora: bring your own activation

Bombora publishes a long list of delivery destinations: Salesforce, HubSpot, Marketo, LinkedIn Campaign Manager, the major DSPs (The Trade Desk and others), and the ABM and paid-media platforms including 6sense, Demandbase, RollWorks and Metadata.io. The data arrives as account lists with topic scores, and each destination decides what to do with it. That flexibility is the reason to buy Bombora. It is also the reason Bombora with nowhere to send it is the most common intent data mistake we see.

A typical Bombora deployment looks like this: 8 to 20 topics tied closely to the product, weekly surge lists pushed into the CRM for sales prioritization and into an ad platform for audience building, with a feedback loop built in the CRM to check which surging accounts converted. Metadata.io, our disclosed sponsor, is one of the paid-media tools that takes Bombora surge lists and turns them into LinkedIn, Meta and display audiences; 6sense and Demandbase do the same inside their platforms.

6sense: activation is the product

6sense's activation is built in. Segments defined by buying stage, fit and intent feed directly into 6sense display advertising, into LinkedIn through its integration, into Salesforce and HubSpot as fields and alerts, and into the 6sense sales workspace where reps see accounts, contacts and recommended actions. Orchestration rules can add accounts to sequences, assign owners and trigger Slack alerts. None of this requires another tool, which is precisely what enterprise buyers are paying for.

The trade-off is that 6sense's advertising runs through its own DSP and reporting, and its contact data is credit-based. If you already run paid media elsewhere or already own a contact database, you will be paying for capabilities you will not use. Our sister site 6sensealternatives.com covers the teams that have hit that wall.

Pricing: what is public and what is not

Bombora does not publish pricing. It sells annual data licenses whose size depends on the number of topics, the delivery destinations and, for some packages, the number of accounts. Public G2 reviews describe it as a mid-five-figure annual commitment for a typical mid-market license, with enterprise deals higher; we treat those as anecdotes, not list prices.

6sense publishes a packaging page with four tiers. The Free tier is for sales users, with limited credits for contact data and basic account identification. Team, Growth and Enterprise are custom-priced and add the predictive model, advertising, orchestration and more credits as you go up. G2 reviews and public commentary consistently describe full 6sense platform contracts as a six-figure annual commitment for enterprise deployments. Again: anecdote, not list price.

The practical summary is that Bombora alone costs less than 6sense alone, but Bombora alone is not a complete solution, and the cost of the activation stack you pair it with has to be counted. A team that buys Bombora plus a paid-media tool plus a sales-engagement tool may or may not end up cheaper than a team that buys 6sense; it depends entirely on what they already own. The intent data pricing page lays out the ranges with sources.

Which to choose, by scenario

You already run an ABM platform, a CDP or a paid-media tool

Buy Bombora. You have the activation layer; you need the widest feed. Adding 6sense on top would duplicate scoring and advertising capabilities you already pay for.

You have a CRM and not much else

Lean 6sense, or Demandbase (see the Demandbase review). A raw Bombora feed into a bare CRM produces lists that nobody acts on. The platform's value is that it turns the list into ads, alerts and sequences without you building the plumbing.

You are a sales-led team that wants names, not accounts

6sense, or ZoomInfo Intent. Bombora is account-level and has no contact database. 6sense bundles contacts on credits; ZoomInfo attaches its contact database to surging accounts.

You sell software and your buyers use review sites

Whichever you pick, add G2 Buyer Intent. Neither Bombora nor 6sense sees the moment a buyer compares you against a competitor on G2. The Bombora vs G2 page covers that pairing.

Your ICP is mostly under 200 employees

Neither, at least not first. Third-party intent coverage thins out for small companies because they do not generate enough research traffic to surge. Start with first-party visitor identification (RB2B or Warmly) and add third-party intent once you have proven you can act on the accounts you already know about.

You are leaving 6sense and want to keep the intent

Bombora is the obvious replacement feed, since 6sense may already have been delivering Bombora topics to you. Pair it with a paid-media tool and a sales-engagement tool and you keep most of the signal for a fraction of the platform cost. Metadata's comparison against 6sense makes that case from the sponsor's side; read it as a vendor page, not a neutral one.
