Bombora Review: Topic Limits, Surge Thresholds and Published Pricing
Bombora's own pricing page publishes a starting figure, a 25-topic ceiling and the surge score thresholds. What that buys, and where the product stops.
Bombora sells account-level intent from a publisher co-op. Its pricing page lists a Growth package starting at $25,000 annually covering 25 topics and the top 25 percent of signals, with Enterprise quoted on request. Company Surge scores run zero to 100, above 60 means increased research, and above 70 is roughly the top quartile.
Key takeaways
- Bombora's pricing page publishes a Growth package starting at $25,000 annually with 25 topics, unlimited users and global coverage, which is unusual disclosure for an intent vendor.
- Company Surge scores run zero to 100: above 60 indicates increased research, and above 70 is approximately the top 25 percent of researching businesses for that topic.
- The Growth package supplies only the top 25 percent band, so the difference between packages is which score range you can see, not a feature list.
- The taxonomy is downloadable in full from Bombora's own navigation, and roughly 44 percent of its topics are company names rather than subjects.

Bombora is the B2B intent data company behind Company Surge. The word also names an Australian surf break and, separately, a band, so to be unambiguous: everything below concerns bombora.com, the co-op that sells topic-level research signals to software and services vendors.
The live B2B intent data guide already covers what a surge score measures against, and the reason buying two intent vendors can quietly mean buying one dataset twice. This page starts where a buyer has to make actual decisions: how many topics you are allowed to track, what score counts as surging, what the vendor's own pricing page publishes, and where the product stops.
The co-op, in the numbers Bombora publishes about itself
Bombora's data comes from a cooperative of B2B publishers rather than from bidstream purchases or scraping, and the "Our Data" page puts numbers on it. That page states the Data Co-op captures signals "of nearly 4.7 million unique domains via 15.8 billion interactions a month, across more than 5,000+ sites", that Bombora resolves those signals to "2.8 million businesses", and that "86% of websites in the Co-op are exclusive to us". The same page describes classification as "BERT-based machine learning", meaning content is scored on what a page is about rather than on which words appear on it.
Those are vendor claims on a vendor page, and they are the ones worth holding onto, because they describe the two constraints that follow you through every later decision. Resolution is to businesses, never to people. And the input is publisher content consumption, so a topic only exists as a signal if the co-op's publishers write about it.

the figure Bombora's Our Data page gives for its taxonomy size
The taxonomy is published in full, and it is mostly company names
Bombora's Our Data page describes its taxonomy as "21,600+ B2B taxonomy or B2B topics". Unusually for this category, the whole list is downloadable without a login: the "Full Topic List" link in Bombora's own Resources navigation points at a spreadsheet at sentry.bombora.com/v2/surge/downloadtopics?type=b2b. The copy pulled for this article on 13 August 2026 carried 21,632 topic rows with the columns Topic ID, Theme, Category, Topic Name and Description, which matches the "21,600+" the marketing page claims.
Reading the file changes how the product looks. Counting its rows rather than taking the vendor's summary, the topics sort into 28 themes, and the largest by a wide margin is Company, at roughly 9,500 rows, or about 44 percent of the taxonomy. Technology is second at around 3,300. Those three figures are counts taken from that download rather than numbers Bombora states anywhere in its marketing. So nearly half of what Bombora tracks is research about named companies rather than about subjects, which is what makes competitive and churn monitoring a first-class use of the product rather than a bolt-on. The tail is genuinely broad, covering Energy, Construction and Manufacturing, Legal, Human Resources, Healthcare and BioTech, alongside a long list of small consumer-adjacent themes.
Bombora's taxonomy guide is explicit that topics are contextual rather than literal, and gives the disambiguation example directly: the models are built to tell "apple" the fruit from "Apple" the company. That distinction is the whole argument for topics over keyword scraping, and it is worth testing against your own category before signing, because a category whose name is a common word is exactly where this either works or does not.
The topic contract: you are buying a couple of dozen topics
Topic count is the practical unit of a Bombora contract, and it is smaller than most buyers expect.
Bombora's pricing page describes the Growth package as carrying "25 topics", with the Enterprise package listed as Custom. The free tier is smaller again: the same page's FAQ offers a Company Surge Alerts account where you "select up to 12 topics" and receive a weekly email of "up to 10 relevant businesses researching your topics".
An independent surface corroborates the same ceiling. G2's integration documentation for Bombora Company Surge states that for that integration "you must select a minimum of 10 topics and a maximum of 25 topics", and that enabling it delivers "up to 25 Bombora Buyer Intent topics directly in my.G2". Two unrelated pages landing on 25 is a strong signal that 25 is the real shape of a standard subscription rather than a quirk of one package.
Bombora's taxonomy guide also recommends how to spend those slots, and the four buckets are a decent planning template whatever vendor you end up with: Brand and Products, Competitors and Partners, Industry and Vertical, and Pain points and Challenges. Twenty-five slots across four buckets is roughly six topics each, which is the constraint nobody models before the contract and everybody argues about afterwards.
What "surging" actually means, in numbers
The live guide explains what a surge score is compared against. The thresholds themselves are published, and they are more specific than most write-ups suggest.
Bombora's pricing page states that Company Surge "scores range from zero to 100", that "Any score above 60 represents an increase in research activity", and that "Scores above 70 represent approximately the top 25% of businesses where there's an increase in research activity for any given topic".
Read that against the package table on the same page and a real difference appears. The Growth package's data coverage row reads "Strongest intent signals (top 25%)", while Enterprise reads "All intent signals". Those two rows are the score thresholds wearing package names. A Growth buyer is seeing the band above roughly 70; an Enterprise buyer also sees the 60 to 70 band, where an account has measurably increased its research without yet being in the top quartile.
That matters for outbound specifically. The 60 to 70 band is earlier, larger and noisier, which is the wrong trade for a small team with one sequence and the right trade for a team that can afford to nurture. Whichever band you buy, the account-level constraint from the live guide still applies: the feed narrows which companies to work, and you still have to choose the people. Bombora's own product pages frame the output as buying stages, mapping accounts to "early research, mid stage research, late stage research".

Price, and the part that is genuinely unusual
Most intent vendors publish nothing. Bombora publishes a pricing and packaging page carrying one figure: the Growth package is listed as "Starting at $25,000 annually", with a "Find out if you qualify" qualifier attached, while Enterprise says "Please get in touch for pricing". There is no monthly option and no toggle on the page, so that annual figure is the only state a visitor sees.
Two rows on that table are worth more than the price. Users are listed as "Unlimited" on both packages, and geographic coverage is listed as "Global" on both. Per-seat pricing is the normal way this category grows expensive after signature, and a vendor publishing unlimited seats at the entry tier removes that particular surprise. The costs that do scale are topics and signal band.
The live intent guide carries a wider reported annual range for Bombora, drawn from what buyers report about negotiated contracts. That range and this figure are not in conflict and they are not the same claim: one describes what deals land at, the other is what the vendor prints. Only the second was verified here.
For a sense of the shape rather than a quote, dividing the published Growth starting figure by its published topic count gives about $1,000 per tracked topic per year. That arithmetic is illustrative and derived only from the two numbers on the pricing page, it is not a rate Bombora quotes, and it ignores every discount, uplift and multi-year term that a real contract carries. Its only use is deciding whether a topic you are considering spending a slot on is worth roughly that much to you.
How the data reaches you, and the second product
Bombora sells signal into other people's software as much as its own. Its site lists native integrations and partner delivery across the B2B stack, naming HubSpot, Salesforce and LinkedIn among featured integrations and 6sense, Apollo and Dun and Bradstreet among featured partners, and the Growth package includes exactly one of those connections. Anyone planning to route signal programmatically should read the connection-shape taxonomy in intent signal APIs for outbound first, because whether a signal arrives by scheduled pull or by push decides what you can do with it.
The distinct second product is Visitor Insights, which Bombora's Insights suite page describes as bringing "de-anonymized site visitor data to life" enriched with firmographic, demographic and intent data. That is a different category from Company Surge and competes with a different set of tools, and de-anonymising traffic on your own site raises match-rate and legal questions that topic intent never raises. Buying Bombora for topic intent does not get you this, and buying it for visitor identification alone would be an unusual choice.
Compliance, and the line that catches senders
Bombora's Privacy Philosophy page states that its "data collection practices create business profiles, not profiles of individuals", and its product pages say the data "is designed to meet the quality and privacy standards (e.g., GDPR, CCPA) of industry leading companies" and that Bombora "has adopted the IAB Transparency and Consent Framework v2.2".
Take that at face value and it still does not do the thing buyers hope it does. The vendor's compliance is not the sender's compliance. A lawfully assembled account-level signal answers where the data came from; the sender still owes their own lawful basis, the country-by-country ePrivacy check set out in GDPR for B2B outbound, and transparency in the first message. On the US side, a co-op that resolves publisher content consumption to companies sits close to the "sell and share" and data-broker material in CCPA compliance, and Bombora's own footer carries a "Do Not Sell or Share My Personal Information" link, which tells you how the vendor reads its own position.
One operational rule from the live guide bears repeating because it is where this product most often embarrasses people: never reference the surveillance itself in a first message. A topic surge is a reason to prioritise an account this week, and it is not a thing to mention to the person receiving your email.
- Yes: Your target account universe is large enough that prioritising it is a real problem
- Yes: You can name 25 topics that matter, across brand, competitors, category and pain points
- Yes: Someone owns acting on a surging account within days, with copy already written
- Yes: You want raw account-level signal to route into your own systems
- No: You expect the feed to tell you which person to contact
- Depends: You want person-level identification of your own site traffic
- Depends: You already buy a platform that resells co-op data, so check for overlap first
Who it actually fits
Bombora fits a team that wants the underlying signal rather than an opinionated platform wrapped around it, that has enough accounts for prioritisation to be a genuine problem, and that has somewhere to put the feed. The unlimited-seat model makes it workable across a whole revenue team instead of two licensed analysts, and the published starting figure makes it one of the few intent products a mid-market company can budget for without a discovery call.
It fits badly where the buyer expects contactable people. It resolves to businesses by design, which is the same account-level-signal, person-level-outreach gap the live guide describes, and no amount of topic tuning closes it. Pair it with firmographic data and technographic data for fit, feed the score into your lead scoring model rather than treating it as one, and keep the response window short enough that the signal is still true when your message lands.

Frequently asked questions.
Frequently asked questions- How much does Bombora cost?
- Bombora's pricing page lists its Growth package as starting at $25,000 annually and its Enterprise package as quote-only. There is no monthly option shown. Both packages list unlimited users and global geographic coverage, so the variables that move price are topic count and which signal band you receive rather than seats.
- How many topics do you get with Bombora?
- Twenty-five on the Growth package, custom on Enterprise, and up to twelve on the free Company Surge Alerts tier. G2's integration documentation independently sets a minimum of ten and a maximum of twenty-five Bombora topics for its connector, which suggests twenty-five is the normal ceiling rather than a quirk of one package.
- What counts as a surging account?
- Bombora's pricing page states that Company Surge scores range from zero to 100, that any score above 60 represents an increase in research activity, and that scores above 70 represent approximately the top 25 percent of businesses researching that topic. The entry package shows only the band above roughly 70.
- Does Bombora tell you which person to contact?
- It does not. Bombora resolves content consumption to businesses, and its privacy page states that its practices create business profiles rather than profiles of individuals. The feed narrows which accounts to work this week, and choosing contacts inside those accounts remains your job, using your own data sources.
