The best intent data providers, tested and ranked

Champify came first of eight with 3 out of 5, the only provider to score above 2.5. It flagged 69 of our 100 known buyers, and 48 of those had buying activity we could verify (69.6%), the most verified signals in the test. Its median signal was 10.1 days old, the freshest we saw. Company details were right for 42 of 69 accounts, and it passed 5 of 8 sourcing and privacy checks. Our Champify review has the full results.

Champify tracks your former customers, champions and lost-deal contacts as they move to new companies, and alerts sales in Slack or by email. It runs as a native Salesforce package and you pay by contacts tracked, with an ROI guarantee on every plan. The catches: almost a third of our buyers were missing, there's no native HubSpot integration, and it starts at $500 a month. Users rate it 4.8 out of 5 on G2 from 54 reviews (checked November 2026).

G2 Buyer Intent came second with 2.5 out of 5. It flagged only 60 of our 100 known buyers, but 42 of those signals held up. That's 70.0%, the highest precision in the test, with a median signal age of 10.3 days. Its coverage score of 3 tied with Champify for the best, while value for money was its weakest part at 2. Read our G2 Buyer Intent review.

It shows which organisations viewed your G2 profile, pricing, comparison or category pages, with a buying stage and activity level refreshed daily, and can sync audiences to ad platforms. But it only sees research on G2 and its sister sites, works at account level with no contact data, needs its own G2 subscription per product and has no public price. Company details were right for 37 of 60 accounts.

Leadspace came third with 2.5 out of 5, scoring 2.5 on every part. It flagged 62 of our 100 known buyers, 38 of those signals held up (61.3%), and its median signal was 10.5 days old. Company details were right for 37 of 62, and it passed 5 of 8 sourcing and privacy checks. Steady rather than standout. More in our Leadspace review.

Leadspace is a B2B data platform more than a feed. It combines its own datasets, intent, technographics and your own data into scored profiles, spots buying groups and pushes results into Salesforce, Marketo, HubSpot or Eloqua. It has run since 2007, but publishes no prices and offers no free trial. Users rate it 4.3 out of 5 on G2 from 109 reviews (checked November 2026), with some mentioning outdated data and slow set-ups.

LoneScale came fourth with 2.5 out of 5. It tied for the most accounts found, flagging 69 of our 100 known buyers, and 44 of those signals held up (63.8%). Data accuracy was its best part at 3. But it passed only 4 of 8 sourcing and privacy checks, and its median signal age of 13.5 days was the oldest in the test. Our LoneScale review explains why.

LoneScale keeps Salesforce and HubSpot filled with verified contacts and flags when key people change jobs, looking up details across a chain of sources and charging credits as you go. Every plan has unlimited users, and the Growth plan adds job-posting signals. It starts at $200 a month, with 100 free credits to try first, but it doesn't name its data sources. Users rate it 4.8 out of 5 on G2 from 60 reviews (checked November 2026).

TechTarget came fifth with 2.5 out of 5. It flagged 69 of our 100 known buyers, 43 of those signals held up (62.3%), and its median signal was 11.8 days old. It got company details right for 45 of 69 accounts, the best result in the test. Compliance was its weakest part at 2, after it passed only 4 of 8 sourcing and privacy checks. See our TechTarget review.

Its Priority Engine shows which companies, and often which people, are reading about enterprise IT topics on TechTarget's own technology publications. The same company sells content syndication, ads and lead generation, so intent can feed paid campaigns. Outside IT it has little to offer, there are no public prices, contracts carry minimum spend, and unused budget may be forfeited.

6sense came sixth with 2 out of 5. It flagged 62 of our 100 known buyers, but only 36 of those signals held up (58.1%), and company details were right for just 34, the fewest in the test. Its median signal was 12.8 days old, and it passed 5 of 8 sourcing and privacy checks. Read our 6sense review.

6sense is a full account-based marketing platform, combining company and contact data, intent and predictive scoring with ads, an AI email agent and sales tools. Its intent comes from its own network plus Bombora, G2, Gartner, TrustRadius and PeerSpot. It lists SOC 2 Type 2, ISO 27001 and ISO 42001, but sells only by quote, and its free Sales Intelligence plan ended on August 12, 2026. Users mention data accuracy problems and a steep learning curve.

TheirStack came seventh with 2 out of 5. It flagged 62 of our 100 known buyers, and 35 of those signals held up. That's 56.5%, the lowest precision in the test, and its median signal was 13.4 days old. It passed 5 of 8 sourcing and privacy checks.

TheirStack turns job postings from job boards, applicant tracking systems and company sites into signals about hiring and the technologies a company uses, at company level. You can search in the app, use the API or webhooks, or plug it into Clay, HubSpot or Zapier. It's the cheapest here, with free sign-up credits and API plans from $49 a month. Users rate it 4.9 out of 5 on G2 from 15 reviews (checked November 2026).

Bombora came last of eight with 2 out of 5. It flagged 59 of our 100 known buyers, the fewest, and 35 of those signals held up (59.3%), with a median signal age of 12.5 days. Ease of use was its best part at 2.5; everything else was 2. See our Bombora review.

Bombora's Company Surge scores companies on how much their staff read about chosen topics across a co-op of publisher sites, from a library of more than 25,300 topics. It's sold as data you deliver into your CRM, ad platforms or warehouse, and 6sense and G2 use it as a source. It is company-level only and publishes no prices. Users rate it 4.4 out of 5 on G2 from 157 reviews (checked November 2026).
