No source compared here ranks providers by ROAS for intent-targeted campaigns, so no vendor can be named as the one that delivers high ROAS. What exists are vendor-published customer results that use different bases (return on ad spend, ROI, pipeline, ad-cost reduction) and give no method. The practical answer is to treat every figure as a claim, fill in a Return Claim Sheet for it, check your audience against the Audience Floor (the smallest list an ad platform will serve), and run your own holdout before you buy.

Who Delivers High ROAS for Intent-Targeted Campaigns: The Short Answer

  • Definition (fact). ROAS is revenue divided by ad spend. An intent-targeted campaign is a paid campaign whose audience is built from intent signals: third-party research activity, your own website visits, or both. The provider supplies the audience, not the return.
  • No ranking exists (fact). The vendor pages compared below publish customer examples, not provider-level ROAS, and none states a sample, a window or a comparison group. Demandbase's advertising page shows placeholder figures only. Bombora's page on advertising performance is a video with a short description.
  • Published numbers mix units (fact). 6sense's advertising page shows Qualtrics at "three times return on ad spend", RepTrak at "3x ROI on LinkedIn spend" and "96% decrease in ad costs", and SAP at "60% reduction to ad costs". Those are different measures from selected customers.
  • A small list may not run (fact). LinkedIn requires a minimum audience of 300 before a retargeting segment can serve in a campaign. Leadfeeder's documentation says the same for company lists synced to LinkedIn.
  • Opinion. Pick the provider whose audience path fits your channel and list size, then measure ROAS yourself against a holdout. Do not pick on a published multiple.

What a ROAS Figure Can and Cannot Show

An intent audience is a targeting decision. ROAS is an outcome ratio. They are linked only if revenue is tied back to ad exposure, and several things break that link.

  • What an intent audience can prove: that an account matched a signal rule on a date, and that you chose to advertise to it.
  • What it cannot prove: that the signal means a buying project, or that the ads caused any revenue.
  • What breaks the link in B2B: long sales cycles mean revenue arrives after the reporting window; many ad results are pipeline, not revenue; and platforms can claim credit for conversions they did not cause. Cometly's guide warns that platforms "are incentivized to show you the best possible numbers" and that their tracking limits mean they "often miss conversions or claim credit for sales they did not truly drive." Cometly sells attribution software, so this is an interested party's view, and it agrees with common sense.
  • What closes the gap: a holdout group drawn from the same audience that sees no ads, and revenue counted from your CRM. This is a method, not a result. For the difference between a signal and a declared buying step, see buying signals vs intent data.

Percepture's primer on what is B2B intent data covers the signal types. The how intent data is collected and scored guide covers where each signal comes from.

The Return Claim Sheet

The Return Claim Sheet is this guide's own tool. Fill one in for every ROAS or return figure before it enters a vendor comparison. A claim with blank fields is marketing copy, not evidence.

Field The question Example of a blank
Who states it Vendor, customer, agency or you? A vendor page quoting a customer
Measure ROAS, ROI, pipeline or cost reduction? "3x ROI" with no definition
Revenue basis Closed-won revenue, pipeline or platform-reported conversions? Not stated
Spend basis Media only, or media plus platform fees? Not stated
Window How long after the ad did revenue count? Not stated
Comparison Against what: no ads, other targeting or last quarter? Not stated
Audience How many accounts, and from which signal rule? Not stated
Source and date Where can a reader check it? A tile with no link

Apply it to the vendor pages cited here. Every published figure fails at least the revenue basis, spend basis, window, comparison and audience fields, because the pages do not state them. That does not make the results false. It means they cannot be compared across vendors.

The Audience Floor

The Audience Floor is the smallest list a channel will serve. It decides whether an intent audience can run at all, and it is the part the vendor pages put in a help article, not in the sales copy.

Fact Source (date shown)
A LinkedIn retargeting segment needs a minimum audience count of 300 before a campaign using it starts serving LinkedIn, Website Visitors Retargeting (Microsoft Learn, no date shown)
Company lists synced from Leadfeeder to LinkedIn need typically at least 300 matched companies; the sync is one-way, company-level only and can take up to 48 hours Leadfeeder Help Centre (June 3, 2026)
6sense segments larger than 1 million accounts cannot be synced to LinkedIn; the integration is set up per user 6sense Support (updated July 16, 2025)

Inference: a narrow ICP, such as a few hundred named accounts, may sit under the floor even before match rates are applied, because not every uploaded company matches. No page compared states a match rate. Opinion: if your list is under the floor, ads are the wrong channel for it, and direct contact with named people is the better test.

One Rubric for the Providers

Each vendor is read against the same columns, taken from the page cited. "Not stated" means the page does not say. The table is split in two with rows in the same order.

Tool Ad audience path documented Return figure on the page cited Source page (date shown)
6sense Segments sync to LinkedIn audiences; Google Ads segment sync named on its advertising page Customer tiles: Qualtrics "three times return on ad spend"; RepTrak "3x ROI on LinkedIn spend"; no method given Advertising page (no date shown); Segments for LinkedIn Ads (July 16, 2025)
Demandbase Advertising and intent offered as one platform; DSP page No figures; the metric tiles show placeholders Advertising page (no date shown)
Leadfeeder List sync to LinkedIn Matched Audiences None Sync Lists with LinkedIn Audiences (June 3, 2026)
RB2B Send identified-visitor data to an ad stack for account-based retargeting; says it is "not a replacement for ad platforms or pixels" and "will not identify every visitor" None; says it helps "close the loop" on spend Using RB2B for Ad Retargeting (January 20, 2026)
Unify Not described on the page cited None Plays documentation (no date shown)
Warmly Adds identified visitors to LinkedIn ad audiences automatically None stated as an ad return Retargeting page (no date shown)
Lead Seeker Not an ad platform; no audience sync None How it works (no date shown)
Tool Identity or intent unit Price on the page cited Relationship
6sense Account-level intent and segments Not stated None
Demandbase Account-level; intent supplied from its own bidstream access, by its own statement Not stated None
Leadfeeder Companies from website traffic Not stated on the help page; Discover from $79 a month on its pricing page None
RB2B Company-level; person-level for primarily U.S. visitors on paid plans Not stated on the help page None
Unify Signals and audiences Not stated None
Warmly Identified visitors Not stated None; its pricing page shows "HubSpot is acquiring Warmly"
Lead Seeker Verified people at ICP accounts, found from public signals Pilot $99 one-time; Starter $149 per month; Growth $499 per month; Scale $1,299 per month Publishes this guide

Fact: Demandbase's guide to intent-based marketing tools, last answered September 18, 2026, lists measurement and revenue attribution as one of seven criteria for choosing a platform and names fifteen tools. It states no return figure for any of them. For a provider-by-provider view that is not about ads, see the best intent data providers guide, the top-rated tools for monitoring customer intent signals guide, and the website visitor identification vendors comparison, which owns billing units for visitor tools.

Map ICP, Timing, Contact and Next Action

Check The question What counts as evidence
ICP Is the account one you serve? Your written ICP: industry, size band, geography, exclusions
Timing How old is the signal, and how long is your sales cycle? The signal's date, and your own cycle length from the CRM
Contact Which people at the account will the ad reach, and who will sales call? A named, verified person with a confirmed role
Next action What should happen when an account engages? An owner, an action and a date, set before the campaign starts

Inference: an ad only reaches an account. A named person still has to answer, so the sales step after the ad decides whether the spend becomes revenue. The guide to intent data to identify sales qualified leads covers that step.

An Illustrative Example

The company and numbers below are invented.

Calderwood Controls sells to about 220 plant-operations teams. Its agency proposes a LinkedIn campaign using an intent audience from a provider whose page says "3x return". The Return Claim Sheet shows the revenue basis, window and comparison are blank. The Audience Floor shows 220 accounts is below 300 before any match loss. Calderwood drops the ad plan, assigns a rep to the 220 accounts, and uses the budget to find named plant and maintenance leaders at the accounts that show a dated public signal. Inference: the test now measures calls and meetings per account, which Calderwood can count itself.

Where Lead Seeker and Percepture Fit

Lead Seeker does not run ads, sync audiences or report ROAS. Opinion: it fits the case where the list is too small for an ad channel, or where ads need a sales follow-up. Following how Lead Seeker works, you describe the ICP and roles, it scans public signals and returns a source-backed dossier with a verified contact and the trigger, and it syncs to Salesforce or HubSpot. Prices come from its live pricing page, checked October 25, 2026. For managed work that combines intent sources with sales action, see Percepture's B2B intent data services. Percepture is the agency Bob Generale leads, and it is related to Lead Seeker.

How to Run the Test

  1. Write the Return Claim Sheet for each vendor figure you are shown, and drop any claim whose revenue basis or comparison is blank.
  2. Count your accounts and compare the list with the Audience Floor of your channel, allowing for unmatched companies.
  3. Choose the revenue basis before launch: closed-won revenue, or a named pipeline stage, taken from your CRM.
  4. Split the audience at random: one group sees the ads, a holdout group does not.
  5. Set the window to at least one typical sales cycle, and record the spend including platform fees.
  6. Compare ROAS and meetings per account between the groups, then decide whether to keep the audience provider.
  7. Fix the follow-up: each engaged account gets a named contact and an owner.

Limitations

  • This is a documentation-based comparison, not a hands-on product test.
  • Documents change. Vendor documentation and service requirements can change.
  • No ROAS was tested. Nothing here measures any provider's return.
  • "Not stated" is scoped to the page cited. A vendor may publish figures elsewhere, for example in a gated report.
  • Customer results on vendor pages are selected by the vendor and use different measures.
  • Some pages carry no date, so dates come from the page when shown.
  • The Return Claim Sheet and the Audience Floor are editorial methods, not standards.
  • The example company and numbers are invented.
  • Related-party rows rely on their own pages. Lead Seeker publishes this guide, and Percepture is a related company.

Frequently Asked Questions

What is a good ROAS for intent-targeted campaigns?

No source compared gives an intent-specific benchmark. Break-even ROAS is one divided by gross margin, so a business with a 40 percent margin breaks even at 2.5. Set your target from your own margin and sales cycle.

Does intent data raise ROAS?

No source compared isolates intent targeting from other changes. Test it with a holdout drawn from the same audience, and count revenue from your CRM.

Can a small account list run as a LinkedIn audience?

Only if it clears LinkedIn's minimum. LinkedIn requires a minimum audience count of 300 for a retargeting segment, and Leadfeeder's documentation says company lists need typically at least 300 matched companies.

How This Guide Was Built

The Return Claim Sheet, the Audience Floor and the example are this guide's own editorial methods, not vendor features or benchmarks. Every tool is read against the same columns, and a cell is filled only from a named page or marked "Not stated". The vendor pages are primary sources for their own features and customer claims, and the platform documentation is primary for its own limits. Labels Fact, Inference and Opinion mark what a source states, what follows from it and what the author recommends. Nothing here is a hands-on test of a product or a client result. This is an October 25, 2026 snapshot.
