How it works

Five places buyer intent data comes from

Every provider sells a view of the same thing: signs that an account may buy soon. The difference is where they look. That choice decides what you can see, how fresh it is, whether you can check it and how much privacy risk you take on.

Publisher co-op

BomboraFive by Five

Member B2B sites share reading activity through a tag. The provider rolls it up to the company and flags topics read more than that company's normal level.

Resolves toCompany

Good atBroad topic coverage, built on logged page views.

Watch forYou see a score, not the pages or the people.

Publisher and review sites

G2TechTargetTrustRadius

One company records activity on sites it owns: articles and downloads on a publisher network, or category and comparison pages on a review site.

Resolves toCompany, sometimes the person

Good atThe provider sees the activity directly, often from logged-in users.

Watch forCoverage stops at that site's audience and categories.

Bidstream

Many resellers

Ad auction requests show which pages load for which IP address. The provider maps the IP address to a company and the page to a topic.

Resolves toCompany

Good atVery wide reach at low cost.

Watch forRemote work and VPNs weaken IP matching, and EU regulators have challenged how bid data is collected.

Your website visitors

Leadfeeder

A script on your own site matches each visitor's IP address to a company, so you see which companies read your pages.

Resolves toCompany

Good atFirst-party: it is your own pricing and product pages.

Watch forOnly covers companies that already found you.

Public business events

Autobound

Dated events that often come before a purchase: funding, SEC filings, new executives, hiring, reviews and posts. Each has a source link.

Resolves toCompany and contact

Good atA rep can check the event and quote it in the first line.

Watch forAn event is a reason to buy, not proof of research. Combine it with fit.

ABM platforms such as 6sense and Demandbase do not add a sixth source. They combine several of these, add their own models and sell the result as scores, stages and audiences. For how a surge differs from a dated event, read B2B intent data and buying signals.

When not to buy intent data

  • Your market is a few hundred named accounts

    You can watch them directly: their news, filings, hiring and visits to your site. A topic score adds little.

  • Nobody will act on it within a week

    Intent loses value fast. A surge in a dashboard that nobody opens is money spent for nothing.

  • Your buyers do not research your category online

    A new category or a niche with little published content gives thin, noisy topic data.

  • You sell to very small companies

    A ten-person company reads too little to show a surge. Events such as funding, formation and hiring cover it better.

  • You have no fit model yet

    Intent on accounts you cannot sell to is noise. Fix your ideal customer profile and contact data first.

Evaluation

Buyer intent software evaluation checklist

Intent products look alike in a demo. These twelve questions show the differences that matter after you sign. Send them to every vendor on your shortlist and compare the written answers.

Source

  • Can the vendor name its sources?

    Named networks, sites or filings, and the share of the data each one supplies.

    Red flag: "Proprietary" with no names, or no answer on how much is bidstream.

  • Is a surge measured against each account's own baseline?

    A surge means more than that company's normal level, not more than the average company.

    Red flag: Large technology companies surge on every technology topic.

  • How specific are the topics?

    Topics as narrow as your product, such as "Kubernetes adoption", not only "cloud".

Matching and evidence

  • Company or person level, and how is the person matched?

    A stated method: a logged-in user, a hashed email or a named contact.

    Red flag: Person-level claims that rest on a job-title guess.

  • Can you see why an account scores high?

    The topics, dates and pages or events behind each score.

    Red flag: A number you have to trust.

  • Does it work for small companies and remote teams?

    A clear answer on coverage by company size and on IP matching for remote workers.

Delivery and freshness

  • How old is the newest record when it reaches you?

    A written refresh cadence (daily or weekly) and the delay to your CRM.

  • Can you take the raw rows out?

    API or bulk files, so you can score intent with your own fit data.

    Red flag: Platform only. Your scoring lives in their tool.

  • Does it reach the place your team works?

    CRM fields, ad audiences, a sales tool or an AI agent: test the one you will use.

Compliance and contract

  • How was consent collected?

    Publisher consent and opt-out, a data processing agreement, and a clear answer for EU data.

  • What exactly do you pay for?

    Account caps, topic caps, seats, contract length and renewal terms in writing.

  • Will they run a backtest on your deals?

    They score 20 recent closed-won accounts using data from before each deal.

    Red flag: They only demo on accounts they chose.

The backtest

  1. Pick 20 accounts that closed in the last two quarters, and 20 that did not.
  2. Ask each vendor what it showed for those accounts in the 90 days before each deal.
  3. Count how often the winners stood out. Evidence you can open beats a score you have to trust.

Why the source matters for privacy

Bidstream data carries the most risk. The UK ICO reported that real-time bidding raised serious data protection concerns (ICO, 2019), and the Belgian regulator found that the ad industry's consent framework broke GDPR (Belgian DPA, 2022). Co-ops say member publishers collect consent (Bombora). Ask every vendor for the same answer in writing.

By API

Topic intent and buying signals in one API

The Autobound Signal API serves co-op topic intent from Five by Five's Market Pulse. Each company and topic gets a composite score from 0 to 100, measured against that company's own baseline, and a stage label. A score of 60 or more counts as surging. The snapshot loads once a week.

The same API key returns dated events across 35 signal types and 700+ subtypes, so you can rank with intent and write with events. See buyer intent signals: fields and coverage.

FAQ

Buyer intent data providers: questions

What are buyer intent data providers?
Buyer intent data providers sell signs that a company, or a person at it, may be getting ready to buy. The signs come from five places: reading activity shared across a publisher co-op, activity on one company's own sites (a publisher network or a review site), ad auction data (bidstream), visits to your own website, and public business events such as funding, filings, hiring and leadership changes.
What is buyer intent software?
Buyer intent software is the product layer on top of intent data. It scores accounts, groups them into audiences and sends them to ad, CRM and sales tools. ABM platforms such as 6sense and Demandbase sell intent this way. Data providers such as the Autobound Signal API sell the underlying records by API, so you can score them in your own tools or give them to an AI agent.
What is the difference between co-op, first-party and bidstream intent data?
Co-op intent pools reading activity from many member sites that run the provider's tag, and compares it with each company's normal level. First-party intent comes from sites one company owns, such as a publisher network, a review site or your own website, so the activity is observed directly but only for that audience. Bidstream intent reads ad auction requests and maps IP addresses to companies. It reaches further but matches less reliably, and EU regulators have challenged how bid data is collected.
How much do buyer intent data providers cost?
Most intent vendors do not publish prices. Bombora, 6sense and G2 show no public price, and Demandbase quotes a platform fee plus a fee per user. Leadfeeder lists a free plan and paid plans. Ask each vendor about account caps, topic caps, seats and contract length. Autobound publishes its credit prices: company intent costs 1 credit per company-topic row, a call with no results is free, and new accounts get 1,000 free credits.
Is intent data GDPR compliant?
It depends on the source, not the category. Ask how consent was collected, whether the vendor signs a data processing agreement and how people opt out. Bidstream data carries the most risk: the UK ICO reported in 2019 that real-time bidding raised serious data protection concerns, and the Belgian data protection authority found in 2022 that the ad industry's consent framework broke GDPR. Company-level scores carry less personal data than person-level intent.
Can I get buyer intent data through an API?
Yes. The Autobound Signal API has buyer intent endpoints for companies and contacts by topic, plus search and enrich endpoints for 35 signal types, all with one API key in the X-API-KEY header. The same data is available to AI assistants through the Autobound MCP server. 6sense, Demandbase and ZoomInfo also offer APIs, usually tied to a platform plan.
Which intent data providers are the best?
There is no single best provider, because each one sees a different slice of buyer activity. Pick by source first: co-op for broad topic coverage, review-site or publisher data for your category, your own site for companies that already know you, and signal data for dated events you can quote. Then run the same backtest on each shortlisted vendor.
