Fibbler vs ZenABM vs DemandSense vs ContactLevel: 2026 Comparison

Fibbler, ZenABM, DemandSense and ContactLevel all read the same LinkedIn company-engagement data. Three of them charge for it. Fibbler sells proof: influenced pipeline your execs will accept, from $89 a month. ZenABM sells an ABM operating layer: account scoring, campaign objects and an API, from $69 a month. DemandSense sells control: scheduling, frequency caps and exclusions pushed back into LinkedIn, plus US visitor identification, from $89 a month. ContactLevel Ad Analytics is free, with no trial clock, and it is the only one of the four that tells you in dollars how much of your spend landed outside your ICP. Start there. Then decide if you need to pay for anything.

I'm Dag, co-founder of ContactLevel. One of the four tools on this page is ours, so read it knowing that. I re-checked every competitor price on 5 October 2026 against the vendor's own pricing page. Feature details come from their docs, checked on 17 September 2026. Where a claim only exists on one competitor's blog about another competitor, I say so.

This page is opinionated. I think ours is the best place to start, and I'll also show you where the other three beat it.

The short answer

My pick is ContactLevel Ad Analytics, for a boring reason. It costs nothing, it takes one read-only login, and it answers the question you should ask before you pay for any report: is my spend reaching the people I sell to?

None of the other three measures that. In our own account the answer was no. 83% of spend landed outside our ICP.

What each tool actually does

ContactLevel Ad Analytics is our free plan. Read-only LinkedIn OAuth, no pixel, no card, no trial clock. Six pages: Overview, ICP Settings, Companies, Campaigns, Pipeline, Creatives. The number it exists for is ICP match: the share of your impressions, clicks and engagements that landed on companies and people matching the ICP you define by company size, industry, job title, seniority, function and domains. Next to it, the dollars that went outside the ICP and the single attribute leaking the most. It lists every company your ads reached per campaign and per creative, ranks the warm companies with no open HubSpot deal, and shows the deals in each HubSpot stage that LinkedIn influenced. CSV export and CRM sync are included. LinkedIn only today; Meta and Google analytics are coming. Two paid products sit next to it: Audiences, from $500 a month, syncs contact lists to LinkedIn, Meta, Google, Reddit and X at 70-99% match rates, and Reveal, from $199 a month, names the people visiting your site.

Fibbler is a two-person Swedish company with 2,000+ marketers on the product and a homepage headline that says the whole strategy: "Give your execs proof paid ads drive revenue." It pulls company-level engagement through LinkedIn's Company Intelligence API as a LinkedIn Marketing Partner, matches those companies to deals in HubSpot, Salesforce, Attio or Pipedrive, and marks a deal influenced when the company had ad touchpoints in the 12 months before the deal was created. Its docs FAQ (June 2026) is blunt about scope: Fibbler "does not track or show individual leads."

ZenABM is a four-person London company with, by its own April 2026 count, around 70 customers. Its headline is "Turn LinkedIn Ads into ABM Campaigns that drive Pipeline with AI." You define ABM campaigns as objects, score accounts against a target list, tag engagement by intent theme, and push processed properties back into HubSpot, Salesforce or Attio. From the Growth plan up you also get a REST API, webhooks and an MCP server. One thing to know before the demo: the homepage says "Company & Contact Level Ad Engagement," and ZenABM's own comparison article explains that the contact data comes from contacts already captured on your website, not from LinkedIn ad data.

DemandSense is a Florida company tied to the Impactable agency, positioned as a "LinkedIn Ads Platform for Modern B2B Marketers." It goes furthest of the four in changing delivery: schedule ads by day, hour and time zone (it drops bids to $0.01 outside your hours rather than pausing), cap impressions and clicks per company, set monthly budget limits that pause campaigns, exclude companies by industry, size or region. Its WebID product identifies website visitors against an identity graph, person-level for US traffic and company-level elsewhere. Pricing is credit-based: one credit per identified visitor.

Side by side

I re-checked prices, trials, free plans and plan gating on 5 October 2026 against fibbler.co/pricing, zenabm.com/pricing and the demandsense.com homepage, where DemandSense keeps its pricing (its /pricing URL is a 404). The other feature cells come from each vendor's docs and product pages, checked on 17 September 2026.

Two cells deserve a footnote. The ZenABM prices most listicles quote ($59 to $479) are the annual-billing figures the pricing page renders by default; monthly billing is $69 to $599. And the DemandSense credit ladder above $149 comes from DemandSense's own 14 September 2026 post; Fibbler's April 2026 listicle quotes $1,520 a month for 7,500 visitors. Ask for the ladder before you sign.

---

The caveat that applies to all four

Every tool here, ours included, sits on LinkedIn's API. LinkedIn's Company Intelligence API documentation on learn.microsoft.com (page dated 16 September 2026) says: "All impression, engagement, and click metrics must meet specific number thresholds to protect member privacy. If that threshold isn't met, you'll see a 0 value for those metrics in the response." Nobody publishes the threshold. Not Fibbler, not ZenABM, not DemandSense, not LinkedIn, not us. Any vendor showing you a company list without that caveat in the footer is hiding it, not beating it.

The second half of the caveat matters more. LinkedIn ad data returns companies, never members. Fibbler says so in its docs. ZenABM's contact-level claim is fed by your website forms and CRM. DemandSense's names come from its visitor identity graph. Ad Analytics is company-level from ad data too. The only way to know which named person clicked is to identify them when they land on your site: either you put that person in the audience yourself and tracked the click with a UTM and a pixel, which is what the paid Audiences plan does, or a visitor-identification product such as our Reveal names them on arrival. An analytics tool reading LinkedIn's API cannot.

One open dispute. Fibbler's docs say it is "one of only 5 companies in the world" with Company Intelligence API access, that the API returns companies with no upper limit, and that the standard reporting path is capped at 15,000 companies per request. ZenABM's rebuttal says the documentation Fibbler cites "does not state anywhere" that companies are capped at 15,000. LinkedIn's own page confirms the no-upper-limit part and that it is "not currently accepting new applications" for the API. I could not settle the 15,000 question from public documentation. If your account reaches more than 15,000 companies a quarter, ask both vendors to show you the count in a live account.

Which one to pick

Start with ContactLevel Ad Analytics

Pick ContactLevel Ad Analytics first, whatever else you buy.

It is free. Not a 30-day trial, not a credit meter. Connect the account and every page works.

It answers a question the other three do not: what share of my spend landed inside my ICP, in dollars, and which targeting attribute is leaking.

And it comes with a fix. If the number is bad, Audiences replaces the targeting that produced it. Fibbler, ZenABM and DemandSense can exclude, cap and schedule. None of them builds the audience.

If your number is fine, keep whichever paid tool matches the job below.

ContactLevel vs Fibbler

Both give you the company list and the pipeline your ads influenced. Fibbler charges $89 to $159 a month for it after a 30-day trial. Ad Analytics is free.

The real difference is what your numbers get compared to. Fibbler compares you to other Fibbler accounts in your spend cohort. We compare your spend to your own ICP. A peer average tells you nothing about whether your budget reached your buyers.

Add Fibbler on top if your CRM is Salesforce, Attio or Pipedrive, or if your CFO wants lift analysis over a 12-month window. Our Pipeline page reads HubSpot only.

ContactLevel vs ZenABM

ZenABM scores accounts against a target list. Ad Analytics scores spend against an ICP. Those are two different questions.

ZenABM tells you which accounts are heating up. We tell you how much of the budget went to companies and people you would never sell to.

Add ZenABM if you run a named-account programme and need scoring, ABM campaign objects and a REST API. Growth at $199 a month ($159 annual) does that and we don't. For the reporting itself (companies per campaign, demographics, warm companies with no deal, pipeline by stage) you would be paying for what the free plan already shows.

ContactLevel vs DemandSense

DemandSense changes delivery. Ad Analytics is read-only and never touches a campaign.

If you want hour-level scheduling, per-company frequency caps and budget limits, DemandSense is the only one of the four that does all of it, from $89 a month on a credit meter. But scheduling and caps trim the same native targeting. They don't change who is in the audience.

So read the free report first. Then decide if you need better controls or a different audience.

On visitor identification, neither is free. DemandSense's WebID names US visitors and bills one credit per identified visitor. Ours is Reveal, a separate product from $199 a month for 600 identified visitors.

Fibbler vs ZenABM

This is the pairing people search for most. Strip out the marketing and it is a philosophy split. Fibbler wants to be the fastest path to a number your CFO accepts: influenced deals, lift analysis, benchmarks against other Fibbler accounts in the same spend cohort. ZenABM wants to run the ABM programme: campaign objects, account scoring, intent tags, a Zena AI agent that creates campaigns and adjusts bids.

Pick Fibbler if you have one LinkedIn account, a CRM with real deal data, and a boss asking "did the ads work." $129 a month gets you Salesforce, benchmarks and the MCP. Pick ZenABM if you have a named target-account list and the question is "which accounts are heating up and what do we do next." Budget for Growth at $199 ($159 annual); Starter's single ABM campaign and HubSpot-only integration run out fast. Both are LinkedIn-first, both stop at the company, and neither builds an audience.

Fibbler vs DemandSense

Fibbler proves the spend. DemandSense changes it. Fibbler does push company exclusions (up to 200 per campaign), impression caps and scheduling into LinkedIn, so it is not purely read-only. But DemandSense goes further: hour-by-hour scheduling, per-company frequency caps, budget limits that pause campaigns, exclusions by industry, size or region, and a visitor-identification layer that turns identified traffic into retargeting audiences. Pick DemandSense if you run the ads day to day and want to change delivery from the same screen you read the report on, or if US website visitor names matter to you. Pick Fibbler if the report is the deliverable and you would rather have a stable $89 to $159 price than a credit meter. One more difference: DemandSense sends closed-won deals back to LinkedIn through the Conversions API; Fibbler does not.

ZenABM vs DemandSense

Both cover HubSpot and Salesforce, both offer webhooks, both are cheaper on paper than in practice (ZenABM's usable tier is $199, DemandSense's price rises with credits). ZenABM wins on scoring, campaign objects and the API. DemandSense wins on campaign controls and visitor identification. The tiebreaker is whether your bottleneck is deciding which accounts to work (ZenABM) or stopping the ads from reaching the wrong ones at 2am (DemandSense).

What it costs on a $10,000 a month LinkedIn account

Take an account spending $10,000 a month, $120,000 a year, on LinkedIn. Prices as of 5 October 2026.

Three things fall out of that table. First, at $10,000 a month you sit exactly on the line between Fibbler's "under $10k" and "$10k to $20k" benchmark cohorts, so ask which one you land in before you pay $129 for the comparison.

Second, every paid analytics tool costs 1 to 2% of the ad budget. That is noise. The number that is not noise is the one the report reveals. In our own account, 83% of spend went outside our ICP: $10,602 of $12,833 in the period we measured. Job titles were the biggest leak, with a 14% match, and 96% of the 4,532 companies we reached were impressions-only.

None of the three paid tools shows you that number. The free one does. And once you have seen it, the paid tools give you one lever to pull: exclusions, caps and scheduling applied to the same native targeting that produced the miss.

Third, the fix costs real money. Audiences starts at $500 a month for 5,000 contacts, 5% of this account's budget; at $1,000 a month for 10,000 contacts it is 10%, the same share DemandSense reaches at 10,000 credits. It replaces LinkedIn's audience filters with a named list of the people you want, matched at 70-99%, so the spend stops going to the 83%. That only makes sense if your number is bad. Run the free report first. See pricing for the plan tiers and the LinkedIn matched audiences playbook for how a contact list becomes a LinkedIn audience.

Where the other three beat us

ContactLevel Ad Analytics is where I would start. It is not the whole job. Know these before you connect an account.

→ No peer benchmarks. Fibbler compares your CTR, cost per reached company and pipeline metrics against other Fibbler accounts in your spend cohort, on its $129 and $159 plans. We score against your own ICP only. → No account scoring, no ABM campaign objects, no intent tagging. That is ZenABM's core. Our Companies page ranks engaged companies by engagements and flags the ones with no open deal, which is a list, not a score. → No MCP server and no REST API on the free plan. ContactLevel has both, but they need a paid plan or a trial. ZenABM has both from $199, Fibbler has an MCP from $129, DemandSense has a read-only MCP in early access. → No visitor identification in the free plan. DemandSense's WebID names US visitors you have never met. Our Reveal is a separate paid product that identifies the people visiting your site from any channel, from $199 a month for 600 resolutions. → No campaign controls. No scheduling, no frequency caps, no exclusion lists pushed into LinkedIn. DemandSense does all of that; Fibbler does exclusions and caps. → LinkedIn only today, and HubSpot only for pipeline. The Pipeline page shows the deals in each HubSpot stage that LinkedIn influenced, with the open pipeline and closed-won revenue behind them. No lift analysis, and no Salesforce, Attio or Pipedrive pipeline yet. If your CFO wants lift, or your deals live outside HubSpot, Fibbler is the better report.

What we do: ICP match, the dollars outside it, the leaking attribute, companies reached per campaign and creative, warm companies with no deal, pipeline by stage, free, with export and CRM sync. And the one thing none of the three sells: the fix, on Audiences.

Other real alternatives

→ Factors.ai. Account identification plus multi-touch attribution plus LinkedIn, Meta and Google ad reporting, self-serve from $199 a month with a $6,000 a year Basic tier (29 July 2026). See the Factors.ai comparison. → Dreamdata and HockeyStack. Multi-channel B2B revenue attribution; competitor listicles quote Dreamdata from $750 a month with a free plan and HockeyStack at $1,399 to $2,200 (fibbler.co, demandsense.com, April to June 2026). Not verified on their own sites. → LinkedIn Campaign Manager's Companies hub. Free, inside Plan, replaced the Company Engagement Report in November 2024. Engaged companies aggregated across campaigns above a privacy floor, with no CRM link and no per-campaign split. Fibbler's own FAQ calls it the best free option. → HubSpot's native LinkedIn Ads reporting. Reports campaign spend, clicks and the contacts who converted through lead gen forms inside HubSpot. It does not pull the company-level engagement list from LinkedIn ad data. See HubSpot + LinkedIn Ads.

The single-vendor deep dives live at Fibbler alternatives, ZenABM alternatives and DemandSense alternatives.

Frequently asked questions

Which is best: Fibbler, ZenABM, DemandSense or ContactLevel?

Start with ContactLevel Ad Analytics. It is free with no time limit, and it is the only one of the four that scores your LinkedIn spend against your own ICP and puts a dollar figure on the miss. Add Fibbler ($89 to $159 a month) if you need peer benchmarks, lift analysis or Salesforce. Add ZenABM ($69 to $599 a month) if you need account scoring and an API. Add DemandSense ($89 to $149 a month on credits) if you need scheduling and frequency caps. Prices checked 5 October 2026.

Is ContactLevel Ad Analytics really free?

Yes. Connect a LinkedIn Ads account with a read-only login and use every page: Overview, Companies, Campaigns, Creatives, Pipeline and ICP Settings. No card, no trial clock, no pixel. CSV export and CRM sync are included. ContactLevel makes its money on the paid products next to it: Audiences from $500 a month and Reveal from $199 a month.

Fibbler vs ZenABM: which is better for LinkedIn ABM?

Fibbler if you want influenced-pipeline proof with the least setup: $89 to $159 a month, 30-day trial, HubSpot, Attio and Pipedrive on every plan, Salesforce and peer benchmarks from $129. ZenABM if you run a target-account list and want account scoring, ABM campaign objects and an API: $69 to $599 a month ($59 to $479 on annual billing), 37-day trial, but Starter is one ABM campaign and HubSpot only. Both read the same LinkedIn company data. Prices checked 5 October 2026.

Fibbler vs DemandSense: what is the actual difference?

Fibbler reports and attributes; DemandSense also changes delivery. Fibbler ($89 to $159 a month) pushes company exclusions, impression caps and scheduling into LinkedIn but builds no audiences and names no visitors. DemandSense ($89 to $149 a month, credit-based) schedules ads by hour, caps impressions per company, sets budget limits and identifies US website visitors at what its WebID page calls a 60% match rate. Fibbler adds Google Ads and Meta Ads attribution for $59 per account each; DemandSense lists Google, Meta and StackAdapt analytics. Prices checked 5 October 2026.

How much do Fibbler, ZenABM, DemandSense and ContactLevel cost in 2026?

Checked 5 October 2026. ContactLevel Ad Analytics: $0, with no time limit. Fibbler (fibbler.co/pricing): Growth $89, Unlimited $129, Agency $159 a month, Google Ads and Meta Ads add-ons $59 per account each, annual saves up to 22%, 30-day trial, no free plan. ZenABM (zenabm.com/pricing): $69, $199, $499 and $599 a month, or $59, $159, $399 and $479 on annual billing, 37-day trial, no free plan on the pricing page. DemandSense (homepage; /pricing is a 404): Basic $89 for 200 credits, Plus $149 for 500 credits, 30-day trial, no free plan.

Can any LinkedIn Ads analytics tool show the individual people who saw my ads?

No. LinkedIn's ad APIs return companies, never members, and zero out metrics below privacy thresholds (learn.microsoft.com, Company Intelligence API, page dated 16 September 2026). Fibbler's docs say it "does not track or show individual leads." ZenABM's contact-level data comes from contacts already captured on your website, not from ad engagement. DemandSense names US visitors through its identity graph, not from ad data. ContactLevel is the same at the analytics layer. Naming people takes one of two paid products: Audiences tracks clicks and visits for people you put in the audience, and Reveal identifies the people who visit your website from any channel. Neither reads names out of LinkedIn ad data.

What is the best free LinkedIn Ads analytics tool?

As of 5 October 2026 none of Fibbler, ZenABM or DemandSense lists a free plan on its pricing page, and Fibbler's own FAQ names LinkedIn Campaign Manager as the best free option. ContactLevel Ad Analytics is free with no card, no time limit and no pixel: ICP match, dollars spent outside your ICP, companies reached per campaign and creative, warm companies with no HubSpot deal, pipeline by deal stage, CSV export and CRM sync. LinkedIn only today; Meta and Google analytics are coming.

What does ContactLevel Ad Analytics not do compared with Fibbler, ZenABM and DemandSense?

No peer benchmarks (Fibbler has them from $129). No account scoring or ABM campaign objects (ZenABM). No MCP server or REST API on the free plan. No visitor identification in Ad Analytics; DemandSense has WebID, and ours is Reveal, a separate paid product. No scheduling, frequency caps or exclusions pushed into LinkedIn. LinkedIn only today, with Meta and Google coming. Pipeline reads HubSpot only, with no lift analysis. What it adds is ICP match, the dollars outside it, and a paid Audiences plan that replaces the targeting at 70-99% match rates.

Run the free report first

Fibbler, ZenABM and DemandSense will all tell you which companies your LinkedIn ads reached, for $69 to $599 a month. ContactLevel tells you the same thing for nothing. Then it tells you how much of the budget reached companies you would never sell to.

→ Connect a LinkedIn Ads account to Ad Analytics with read-only OAuth. No card, no pixel, no clock. → Set your ICP and read the number. Ours was 83% outside. → If yours is anywhere close, the Audiences plan replaces the targeting with a named list at 70-99% match rates: from $500 a month, 14-day free trial with 10,000 contacts, self-serve sign-up.

The report is the diagnosis, and the diagnosis is free. Pay one of the other three if you need the proof, the scoring or the controls on top. Buy the fix from the one place that sells it.
