Best Buyer Intent Data Providers: Types, Examples and How to Choose
The best buyer intent data provider is the one whose data source matches where your buyers research. Bombora draws on a co-op of B2B publishers, G2 on software review activity, Informa TechTarget on its technology sites, and 6sense, Demandbase and ZoomInfo bundle intent into broader platforms. Test any provider against your past wins before buying.
What an intent data provider sells
An intent data provider tells you which companies appear to be researching a topic right now, usually a topic tied to your category or your competitors. You buy it to answer one question: of the accounts that fit our customer profile, which ones should we contact this week?
Almost all third-party intent is account-level. It tells you a company is researching, not which person. Turning that into outreach needs a second step: finding the right contacts at the account and deciding what to say.
First-party intent: what you already own
Before buying anything, count the signals you already collect: visits to your pricing page, repeat visits to comparison pages, trial signups, email replies, abandoned checkouts. These are specific to your product and you control how they are gathered. Their limit is coverage: they only show accounts that have already found you. Third-party intent exists to show the much larger group researching your category on other sites. Most small teams get more from wiring their first-party signals into follow-up than from a third-party feed, so do that first.
Third-party provider types, with real examples
Providers differ mainly in where their data comes from. That source determines what the signal can and cannot tell you.
Publisher co-op: Bombora
Bombora says its Company Surge data comes from a Data Co-op of thousands of B2B media sites and brands, collected through a consent-driven tag. It describes its scoring as relative and account-specific, comparing the last three weeks of an account's research on a topic with a 12-week baseline, so a surge means more research than that company normally does. Bombora describes Company Surge as account-level, with persona insight as a separate layer.
Review site: G2 Buyer Intent
G2's documentation says its signals fire when buyers view your product profile or pricing, compare your product with a competitor, or browse alternatives and category pages that include you. Signals are grouped by buyer organisation, are delivered per product, and the signal types you receive depend on your G2 plan. Because the activity happens on a software review site, it skews toward later-stage evaluation, but only for categories with real G2 traffic.
Owned publisher network: Informa TechTarget Priority Engine
TechTarget, which combined with Informa Tech's digital businesses in December 2024 to form Informa TechTarget, sells purchase intent from research activity on its own network of technology sites. It fits companies selling enterprise technology, and has little relevance outside that market.
Platforms that bundle intent: 6sense, Demandbase, ZoomInfo
6sense and Demandbase are account-based marketing platforms that package intent alongside account identification, scoring and advertising. ZoomInfo sells intent signals alongside its company and contact database. With bundled platforms, ask which intent sources feed the product, since some combine their own signals with partner data.
How to evaluate a provider
Ask these before signing anything:
- Source. Where is the activity observed, and how is it collected and consented? Ask about bidstream data specifically.
- Resolution. How is activity tied to a company? IP-to-company matching weakens with remote work, so ask how the provider handles home networks.
- Coverage of your market. Does the topic list include the problems your buyers research, in their language? Does coverage reach companies of your customers' size? Many feeds are thin below mid-market.
- Freshness. How often are scores updated, and how quickly can a surge reach your CRM?
- Delivery. Does it push into your CRM as a field or a task, or only into its own dashboard that nobody opens?
- Privacy terms. What legal basis supports collection in the EU and UK, and what can you lawfully do with it?
Run a backtest before you buy
Vendor case studies cannot tell you whether a feed works for your market. A backtest can. Give the provider a list of accounts that became customers in the last year and an equal list of good-fit accounts that did not, and ask for each account's intent history for the months before each deal opened. If surges show up before your won deals noticeably more often than for the comparison group, the feed carries signal for you. If they look the same, the data will create busywork. Then run a short pilot: route surging accounts to one rep and compare meetings booked against a control list.
When third-party intent is not worth it
Skip it for now if your total market is a few hundred named accounts that you can simply cover, if your deal sizes cannot pay for an enterprise data contract, if your category is too new or niche for providers to have topics that match it, or if nobody has time to act on signals within days. Intent decays quickly, and an unread feed is the most expensive version of it.
Using intent without sounding like surveillance
Never tell a prospect you saw them researching a topic. Use the signal to decide when to reach out and which problem to lead with, then write as you would to any well-chosen account. Pair account intent with fit: a surge from a company you cannot serve is noise.
On the first-party side, Koryo's pixel turns a known visitor who views pricing into a hot lead with at most one follow-up a week, without storing IP addresses and while respecting Global Privacy Control, so the signals you own reach a person or agent quickly.
Frequently asked questions
- What is the difference between first-party and third-party intent data?
- First-party intent comes from your own channels: pricing page visits, email replies, trial activity and checkouts. Third-party intent comes from activity on other sites, such as publisher networks or review sites, attributed to companies by a provider. First-party data is more precise but only covers accounts that already know you; third-party data reaches accounts researching your category elsewhere.
- Does intent data tell you which person is researching?
- Usually not. Most third-party intent, including Bombora's Company Surge as Bombora describes it, is account-level: it shows that a company is researching a topic, not who. G2 groups signals by buyer organisation. You still need contact data and judgement to decide whom to reach at the account, which is why intent works best alongside fit criteria.
- How do you test whether an intent data provider works?
- Run a backtest and a pilot. Ask the provider for historical intent on accounts you won and on similar accounts you did not, and see whether surges appeared before your wins more often. Then route current surging accounts to one rep for several weeks and compare meetings booked against a control group of fit accounts.
- Is third-party intent data legal to use under GDPR?
- It depends on how the provider collected the data and what you do with it. Ask each provider for its legal basis for collection in the EU and UK, whether it uses bidstream data, and what personal data, if any, it passes to you. Using intent only at company level to prioritise accounts carries less risk than enriching individuals. This is not legal advice.
