Fibbler vs ZenABM vs DemandSense: 2026 Comparison

Fibbler, ZenABM and DemandSense read the same LinkedIn company-engagement data and sell three different things on top of 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. None of the three puts a dollar figure on the spend landing outside your ICP, and none of them can replace the targeting that produced it. That is what ContactLevel's free Ad Analytics measures, and what the paid Audiences plan fixes.

I'm Dag, co-founder of ContactLevel. We ship a free LinkedIn Ads analytics product that competes with all three tools on this page, so read this knowing that. Every competitor price and feature below was checked on 17 September 2026 against the vendor's own pages. Where a claim only exists on one competitor's blog about another competitor, I say so. This page is opinionated. It is also the comparison I would want if I were shortlisting.

What each tool actually does

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 is the only tool of the three that writes to your campaigns in a way that changes 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.

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 engagement per HubSpot deal stage. LinkedIn only today; Meta and Google analytics are coming. The paid Audiences plan is the fix: contact-level audiences synced to LinkedIn, Meta, Google, Reddit and X at 70-99% match rates.

Side by side

Every competitor cell was checked on 17 September 2026 against fibbler.co/pricing and the Fibbler docs, zenabm.com/pricing and the ZenABM docs, and the demandsense.com homepage, where DemandSense keeps its pricing (its /pricing URL is a 404).

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 have 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 and what an analytics tool 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

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).

Where Ad Analytics fits

Pick ContactLevel Ad Analytics first, whatever else you buy, because it is free and 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. If that number is fine, keep whichever paid tool matches the job above. If that number looks like ours did, the report is the least of your problems.

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 17 September 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 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. A $129 report that surfaces a $10,000 monthly miss is the best money in the stack. It is also the moment you realise the tools on this page give you one lever to pull afterwards: exclusions, caps and scheduling applied to the same native targeting that produced the miss.

Third, the fix costs as much as the miss. Audiences at $1,000 a month is 10% of this account's budget, 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.

The honest boundary

ContactLevel Ad Analytics does not do several things all three competitors do, and you should know them 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. ZenABM has both from $199, Fibbler has an MCP from $129, DemandSense has a read-only MCP in early access. → No identification of anonymous strangers. DemandSense's WebID names US visitors you have never met. Website Visits identifies people already on your list when they land on the pixel, on paid plans. → 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 pipeline by deal stage rather than multi-touch revenue attribution. We do not compute influenced closed-won revenue over a lookback window. If your CFO wants that number, all three competitors produce it and we do not.

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.

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.

Frequently asked questions

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.

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; person-level click and visit tracking exists only in the paid Audiences plan, for people you put in the audience.

What is the best free LinkedIn Ads analytics tool?

As of 17 September 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 identity-graph identification of anonymous visitors (DemandSense). No scheduling, frequency caps or exclusions pushed into LinkedIn. LinkedIn only today, with Meta and Google coming. Pipeline by HubSpot deal stage rather than multi-touch revenue attribution. What it adds is ICP match, the dollars outside it, and a paid Audiences plan that replaces the targeting at 70-99% match rates.
