TL;DR
- Snitcher has the clearest documented multi-client partner portal in this comparison. Its agency dashboard lists client accounts and billing status; entry pricing starts at $49/month, but a partner account does not mean one subscription covers every client.
- Albacross merits a test for European B2B traffic and a combined visitor-to-outreach workflow. Its current Starter price is €59/month billed yearly; HubSpot integration is listed under the €149/month Professional plan. The older €79 figure in this article was stale.
- RB2B is the most direct test when a US client specifically wants a match to an individual visitor. Its person-level identification is US-only. Starter is $79/month and Pro starts at $149/month; Pro/Pro+ list $99/month for up to five additional domains. Additional domains are not proof of separate client permissions.
- Leadfeeder is a practical company-identification choice when a client wants site-visit context and CRM handoff. Discover starts at €79/month billed annually. Activate starts at €369/month and adds verified contact data, which does not mean those contacts personally visited.
- Warmly can suit a high-value client wanting visitor identification and engagement in one programme. Its published AI Web-Deanonymization starting tier is $10,000/year. Price the actual client deployment and service labour before calling it too expensive or profitable.
- Buy on accepted client actions per month, not a vendor's headline identification percentage. Test each client domain separately, and keep company matches, suggested contacts and identified visitors in different reporting columns.
The agency buying problem
A software vendor can identify companies visiting one website and call the implementation finished. An agency has a more difficult job: the manufacturing client in Germany, the US software client and the UK consultancy must each receive their own account, rules and explanation of what the data means. The agency needs enough margin to review matches, remove bad records and send the client a useful action, not another chart of anonymous sessions.
Start with tenant separation. Ask who owns each account and tracking script. Can the agency switch among clients without one client viewing another's domains, CRM credentials or exports? Can the client leave with its own history and configuration? A shared login is not multi-client support. Neither is adding five domains to one account if permissions, notifications and billing cannot be separated.
Then ask what was identified. A company-level match says an organization may be associated with a visit. A contact database may suggest employees at that company. Neither proves that the suggested employee opened the page. Person-level identification is a different claim, with narrower geographic and privacy conditions. Reporting that confuses these layers can damage a client's outreach and an agency's credibility.
Finally ask what a client can do. The client may already know the visiting company, may have an open deal, or may sell to a different subsidiary. The useful output is a reviewed account, relevant page context, assigned owner and suggested next step. Our wider B2B intent data providers guide covers other signal sources; this comparison is for agencies deploying identification across client sites.
Five tools compared
| Tool | Identity the agency can report | Published starting point | Multi-client question | Strongest fit |
|---|---|---|---|---|
| Snitcher | Company visit; decision-maker contacts are separate data | $49/month | Partner portal lists separate client accounts; check client subscription and role setup | Several small B2B client accounts |
| Albacross | Company visit plus contact and outreach data | €59/month Starter, annual billing; Professional €149/month | Confirm separate client tenants, permission level and billing | European B2B client with outbound follow-up |
| RB2B | US person-level; company-level internationally on paid plans | $79/month Starter; Pro from $149/month; extra domains on Pro/Pro+ $99/month for up to five | Are extra domains isolated or pooled? | US client demanding named-visitor evaluation |
| Leadfeeder | Company visit; verified contacts in higher plan are separate | Discover €79/month, annual billing; Activate €369/month | Confirm partner administration and per-client contract | Company-level identification and CRM activity |
| Warmly | Visitor contacts and companies; scope depends on plan and traffic | AI Web-Deanonymization from $10,000/year | Quote client workspaces, credits and agency rights | High-value client adding engagement workflows |
Prices are vendor-published starting figures checked on 27 September 2026, not quotes for a five-client portfolio. They use different currencies, billing commitments, capacities and products. A cheap starting plan can be dearer if it cannot export the needed data or support the client's CRM. The test below compares the delivered service, not just subscriptions.
1. Snitcher
Best for: an agency that wants a documented partner operating model for several clients and needs company-level identification at an accessible starting price.
Snitcher's agency portal documentation describes a central dashboard for invitations, active client accounts, subscription status and billing ownership. That is meaningful: an account manager can see whether a client has signed up and who manages payment without keeping a spreadsheet of personal logins. Its partner programme also offers a free partner account for demos and training. The documented client signup link gives the client a first-year discount; it is not evidence that the agency receives unlimited client licenses for one $49 payment.
The vendor's product comparison page says plans start at $49 per month and scale by the number of identified companies. It also says the underlying visit is resolved from an IP address to a company, while separately supplied business contacts are people worth considering for outreach. An agency should label those outputs differently. “Acme visited the security page” is materially different from “Acme's operations director visited.”
In a pilot, put two client sites on separate accounts and invite a client user into only one. Export activity and verify the client's access boundary. Then sample 50 identified companies: remove ISPs, hosting providers, existing customers and companies that do not match the client's target market. Observe the effect on the actual pricing tier. A price per identified company can be attractive for a small specialist site and less so for a high-volume broad-audience site.
Where it falls short: Snitcher does not claim that the suggested decision-maker is the visitor. If the client needs person-level site attribution, this product alone does not answer that request. The live article claimed a unique certified programme and superior resistance to VPNs and privacy browsers without a defensible comparative test; neither should drive procurement.
2. Albacross
Best for: a European-market client that wants to move from a company visit into segmentation, contact discovery and outreach while keeping the source of each piece of data clear.
Albacross's current pricing page lists Starter at €59/month billed yearly, Professional at €149/month billed yearly, and an Organisation tier by quote. Starter includes visitor filters, Slack/Teams notifications and Pipedrive integration. The page places HubSpot integration, CSV export and Google Sheets export under Professional. That matters more than the headline price when the agency's deliverable is a HubSpot account list. An agency promising that result from the entry plan would need to check the current entitlements or upgrade.
The product combines site identification with verified email and phone credits, prospecting and outreach features. That may reduce handoffs for a client whose seller wants one place to review a visiting company, select a relevant employee and start a campaign. It also creates two different identities in one interface. A suggested contact from a data waterfall is not a person-level match to the website session. In the client report, show company evidence, contact source and verification status in separate columns.
Test the market you actually serve. A Swedish agency with industrial clients can compare matched companies on Swedish, German and US traffic, then inspect legal-entity and subsidiary accuracy. It should review its own tracking notice, consent configuration, contract and data transfer terms with counsel where applicable. A vendor's general compliance claim cannot decide every client's obligations.
Where it falls short: Professional can be the effective floor when export or HubSpot sync is essential; the cheapest displayed tier is then misleading for the buyer's workflow. Confirm agency access, client isolation, credits and cancellation terms in writing before rolling it across accounts.
3. RB2B
Best for: an agency testing whether named US visitor resolution produces a better client action than company identification alone.
RB2B's published price table puts Starter at $79/month with 300 monthly resolutions and Pro from $149/month. Starter can push LinkedIn URLs to Slack or Teams, but the table does not include business email addresses or the wider integrations at that tier. Pro adds business emails and other integrations. A “person-level tool” comparison that assumes HubSpot export and email on the entry plan would overstate what the buyer gets.
The same table shows $99/month for up to five additional domains on Pro and Pro+. That is commercially interesting for an agency, but it should prompt a security demonstration, not an immediate five-client purchase. Ask whether each domain can have different users, suppression lists, CRM connections, notifications, credit reporting and data exports. If not, buy separate accounts or a documented agency arrangement. Do not confuse domain capacity with permission isolation.
RB2B's global tracking guidance says person-level identification applies to US visitors. Paid Starter, Pro and Pro+ accounts also receive company-level identification outside the US, with credits consumed there too. The vendor says customers must configure their own consent-management setup for international tracking; it does not enforce consent for them. That makes RB2B a narrower choice for a mostly European portfolio than the phrase “global visitor ID” might suggest.
For a US client, sample the people returned and have the client's owner verify title, employer, page relevance and whether outreach is appropriate. A named profile is only valuable if those checks produce an acceptable action. Compare cost per accepted action, including resolutions and overages, against a company-level tool with a separate contact lookup.
Where it falls short: US person-level coverage is the central constraint. Agencies also need a clear answer on multi-domain access and credit allocation before treating the published add-on as a client management system.
4. Leadfeeder
Best for: an agency that wants company visits, page context and a CRM handoff, with a free low-volume way to show a client the format before a paid commitment.
Leadfeeder's current pricing offers a free Lite plan after the trial: seven days of visitor history and up to 100 identified companies monthly. Discover starts at €79/month billed annually for company identification, alerts and CRM push. Pricing then increases with monthly identified-company volume. Activate starts at €369/month billed annually, adding verified contacts, intent filtering and other activation tools. The higher tier is a different purchase, not a trivial feature toggle.
An agency can use the Lite period to show a client what a reviewed account brief looks like: company, page viewed, existing CRM status, target-fit reason and owner action. It should not promise a stable service on seven days of history if the client needs monthly trend analysis. On Discover, test the CRM mapping with a subsidiary, an account that already exists and a visitor with no useful target fit. Keep enriched contacts separate from evidence of who browsed.
Leadfeeder is useful when the client's sales team already acts on company-level account signals. A company looking at a pricing page can be worth checking even if the person is unknown. It is less useful when the client insists on a verified named visitor or when the agency cannot staff the review of false and low-value matches.
Where it falls short: the entry price is tied to company volume and annual billing; Activate's contact features cost considerably more. Confirm per-client workspaces and agency administration in the contract rather than assuming that a general partner programme supplies them.
5. Warmly
Best for: an agency serving a client with enough account value and operational capacity to use identification and live engagement together.
Warmly's pricing page lists AI Web-Deanonymization from $10,000/year, with 10,000 credits per month at the starting level and both contact and company visitors in the product description. The separate GTM Signals Package is another $10,000/year if purchased. These are starting list figures, not the price for ten client workspaces. Ask for a written proposal showing which clients, domains, credits, integrations, workflows and staff seats it covers.
This is not automatically a poor agency product because of the annual number. For a client paying a $3,000 monthly retainer, a $10,000 annual software charge is about $833/month, leaving roughly $2,167/month before staff time, other software and overhead if the agency bears it. That may be viable for a high-value account programme, or it may erase the service margin once implementation and review are included. The answer depends on contract allocation and accepted pipeline work, not a blanket rule.
The practical pilot should focus on one client with a clear action: for example, alert an account owner when a known target account returns to a product page, then compare that alert with the CRM's open opportunities and suppression list. Ask which contact-level claims can be supported for the client's traffic, and what happens when identity is uncertain. Do not buy live chat, AI agents or the additional signals package because the platform offers them; add them only if they change a measured client outcome.
Where it falls short: a higher starting commitment and quote-dependent multi-client rights make this a poor default for a portfolio of small clients. The agency must also operate and measure the workflow, not just install the script.
The five-client cost test
Suppose an agency has five B2B clients, each paying $3,000/month for research and outbound support. The agency is considering adding visitor identification. It should build a cost sheet per client, even if the vendor offers a shared agency invoice. Currency conversion and tax belong in the actual budget; the example below uses dollars only for the agency service fee and an illustrative software allocation.
| Monthly line, per client | Illustrative amount | Why it belongs |
|---|---|---|
| Client service fee | $3,000 | Revenue available to fund delivery |
| Vendor license or allocated share | $250 | Replace with plan, credits, domains and overage quote |
| Analyst review: 6 hours at $45 loaded | $270 | Remove false matches and decide relevance |
| CRM and reporting: 3 hours at $45 loaded | $135 | Maintain mapping, suppression and client report |
| Remaining contribution before other overhead | $2,345 | $3,000 minus $250, $270 and $135 |
The $250 license is not any vendor's quoted price. It is a placeholder that makes the decision calculable. For five clients it would be $1,250/month in license allocation and $11,725/month remaining contribution before other overhead, assuming identical fees and effort. A vendor may instead require five contracts, a partner minimum, a domain add-on, higher resolution volume or a yearly prepayment. Those terms change cash flow and contribution. Have sales quote the five exact domains and tell you whether credits are pooled, and then replace the placeholder.
Also calculate cost per accepted action. If a client pays $250 in tool allocation and $405 in labour, and its sellers accept 13 account actions in a month, the direct cost is $655 ÷ 13 = $50.38 per accepted action. If they accept only two, it is $327.50. Neither figure proves ROI; it shows whether the output is economical enough to test against pipeline. A dashboard full of matches that no client accepts is expensive at any starting price.
A 30-day pilot clients can understand
Choose two contrasting clients: one US-heavy site and one European site. Keep their accounts, consent configuration, CRM credentials and reports separate. Run a 14-day setup and observation period, followed by 16 days of reviewed delivery. Record baseline traffic and the relevant pages before installing a new tag so you can distinguish low coverage from low buyer traffic.
For every returned record, capture client, domain, visitor country, vendor identity level, company name, matched domain, page context, timestamp, suggested contact source, current CRM status, exclusion reason, owner and accepted action. Do not let a contact suggestion inherit the label “visitor.” Manually inspect at least 50 matches per client, with an oversample of high-value accounts and obvious ambiguous domains. Where a tool claims person-level results, review those separately. Remove competitors, the client's own offices, service providers and existing customers according to that client's brief.
At the end, report counts in a funnel: sessions eligible for the vendor; identified companies; target-fit companies; correctly mapped CRM accounts; owner-reviewed accounts; accepted actions; meetings or opportunities that followed. This is not a controlled causal study, but it reveals where a vendor's attractive match rate stops turning into useful client work. Ask the client which three examples were useful and which three were embarrassing. Those six records often expose identity and workflow problems more clearly than an average rate.
Then test permissions: client A should see only A's history and exports; a staff member assigned to A should not reach B's data; removing the agency's access should leave the client with its own account. Get the actual invoice or quote and compute accepted-action cost. Renew or expand only when the client can name a repeatable response to the signal.
Which tool should an agency choose?
For a mixed portfolio of smaller B2B clients, pilot Snitcher first if company-level identification suffices and the partner portal's separate client accounts match the agency's operating model. For a European client that needs visitor data connected to outreach and HubSpot, pilot Albacross Professional, because the entry tier does not list the HubSpot integration. For a US client asking who personally visited, pilot RB2B Pro against the actual people the client will contact, and verify extra-domain isolation before putting clients together.
Choose Leadfeeder Discover when the client wants identified companies and CRM activity, and use Lite to demonstrate the report format before committing. Consider Warmly for a client with high-value target accounts and a team ready to operate engagement workflows; get a deployment-specific quote. No ranking replaces a same-traffic pilot. A company match can be useful without a name; a named profile can be useless if the client cannot act responsibly on it.
If a client needs signals beyond its own website, compare intent tools for HubSpot teams and the broader buying signal platforms. For a portfolio concentrated in Europe, our European visitor identification comparison gives the geography a closer look.
Use the Signal-Based Outbound Playbook to define which identified accounts deserve follow-up and which should remain research signals.
FAQ
Can one agency subscription cover five client websites?
Sometimes a plan permits multiple domains, but that is not the same as separate client accounts. RB2B lists an additional-domain charge on higher plans; Snitcher documents a portal for managing client accounts. Ask each vendor for a five-domain quote and demonstrate permissions, billing, exports and handover before sharing a subscription.
Does identifying a company tell the client which employee visited?
No. A company match and a list of relevant employees are different data products. Unless the tool actually resolved a person-level visitor under the applicable conditions, the client should say that the company was associated with activity, not that a named employee viewed a page.
Which tool supports person-level identification outside the United States?
Do not assume any global promise covers every geography and plan. RB2B's published guidance specifically limits person-level identification to US visitors and describes international results as company-level on paid plans. Ask other vendors to show the identity level and lawful collection method for the client's actual traffic by country.
Is the cheapest starting plan the cheapest agency option?
Usually that cannot be known from the banner price. Albacross lists HubSpot and CSV export on Professional, not Starter. Leadfeeder's entry Discover plan differs from Activate's contact features. RB2B's extra domains, resolutions and integrations depend on plan. Add review labour and unused matches to the quote before comparing costs.
How should an agency report match rate to a client?
State the denominator: eligible sessions or unique visitors, date range and country mix. Separate company matches from person matches, then show how many matched the client's target accounts and led to accepted actions. Vendor-reported coverage on a different traffic sample is not the client's result.
What should happen when a client ends its contract with the agency?
The client should be able to retain its own vendor account, tracking configuration, history and CRM connection according to the contract. Establish ownership and export rights before installation. Revoke agency staff access at offboarding and verify that no other client's data is included in the export.
