Cognism vs Supered ProspectorOne database for Europe, or every provider through Clay.
Cognism sells its own contact database, strongest in the UK and Europe, with phone-verified mobiles and Do Not Call screening, on a quote. Prospector sells no data: it puts the Clay tables your GTM engineer already built in every rep's hands, on LinkedIn, on company sites and in the CRM record, for $45 per rep per month. If you have no Clay and your buyers are mostly in Europe, buy Cognism. If you run Clay, Clay plus Prospector is the better way for a sales team to prospect: GTM engineers build in Clay, reps never open Clay.
01Supered ProspectorTeams already on Clay who want every rep running the tables from where they prospect, a one-click CRM sync, and each list tracked found, worked and closed. $45 per rep per month, billed annually, from 1 rep.
02CognismMid-market and enterprise teams with no Clay who call into the UK and Europe and want verified mobiles, Do Not Call screening and the compliance paperwork from one vendor. Quote only, 5 seats per package.

Status check
What is Cognism selling in October 2026?Two packages, no price on the page.
Cognism's pricing page sells two Sales Prospecting packages, Standard and Pro, each with "5 seats included," and no dollar figures: every button reads "Talk to sales" (cognism.com/pricing, checked 2 October 2026). Usage runs on credits: "1 credit = 1 revealed contact," with "No charge for viewing previously revealed contacts," and "A credit is only used again if that contact changes jobs." Pro adds premium mobile data, on-demand verification and intent from Bombora, where "Administrators can select up to 12 intent topics from a library of over 11,000 options." MCP and API access now appear on the page, marked New.
What a quote turns into is on Vendr: the median Cognism buyer pays $32,750 a year, across 94 purchases, with buyers saving 26% on average and contracts running from $16,585 to $88,449 (Vendr, checked 2 October 2026). Cognism also owns Kaspr, a self-serve extension for individual reps and small teams.
One fact matters for teams on Clay: Cognism is not in Clay's marketplace. Clay's integrations page lists "200+ providers in one place," and its Cognism integration address returns a Not Found page (clay.com, checked 2 October 2026). So the question is not whether Cognism's data is good. It is whether one database, sold by the seat, is the right purchase once your GTM engineer is building waterfalls in Clay.
The decision table
Cognism vs Prospector at a glanceNine lines that decide it.
Cognism
Supered Prospector
Job it is built for
One vendor for B2B contacts, strongest in the UK and Europe, with phone-verified mobiles, intent on Pro and compliance work done for you.
Clay in every rep's hands: the tables your GTM engineer built become a button reps press where they already prospect. No database of its own, no outreach writing.
Data source
Cognism's own database, including manually phone-verified "Diamond Data" mobiles, scrubbed against "15 major Do Not Call and TPS lists."
Clay's waterfall across 200+ providers, on your own Clay account and credits. Cognism is not one of them today.
Where reps use it
Cognism's web app and its Sales Intelligence Extension (4.3 out of 5 from 11 ratings, 4,000 users) on LinkedIn, Sales Navigator and company sites, with an active Cognism seat.
Inside the Supered Chrome extension: LinkedIn profiles, Sales Navigator, company websites, and HubSpot, Salesforce and Pipedrive records. Reps never log into Clay.
CRM sync
Integrations with "Salesforce, HubSpot, Outreach, Salesloft and more," set up in the Cognism platform; a CRM Enrichment add-on keeps records current.
One click to HubSpot, Salesforce or Pipedrive, field mapping set once by Ops. Before the push, the rep sees the matching CRM record, who owns it and whether the person was worked before.
Pricing model
No published price. Standard and Pro, 5 seats each, one credit per revealed contact. Vendr median $32,750 a year from 94 purchases.
Published: $45 per rep per month, billed annually ($540 a rep a year), from 1 rep. Enrichment runs on the Clay credits you already buy.
Contract and limits
Annual, negotiated. Fair-usage policy per user: 2,000 records viewed and 2,000 exported a month, exports 25 records at a time.
Annual, from a single seat. No free trial yet: it starts with a demo on your own Clay account.
What leaders see afterward
Credits used per revealed contact. What happens to the contact after that lives in your CRM reports.
Every list found, worked and closed, per rep, with closed outcomes Qualified, Recycled or Disqualified, and no duplicate work across reps.
Security and compliance
SOC 2 Type II, ISO 27001 and ISO 27701; GDPR and CCPA; data generally kept inside the EEA.
SOC 2 Type II and GDPR (Supered). Each provider in your Clay waterfall keeps its own sourcing terms.

How we graded: by the job, because the two products do different ones. Lane one is a team with no Clay that calls into the UK and Europe and wants one vendor for verified mobiles and compliance. Lane two is a team on Clay that wants every rep running the tables. Weights in both lanes: contact coverage the rep can reach for that market (35%), where the rep works and the CRM sync (25%), what a leader sees about each list afterwards (20%), price and contract for a 10 to 50 rep team (20%).

Its extension runs Cognism's data only, and Cognism is not in Clay's marketplace. A GTM engineer can still call its API from a Clay table on your own contract.
Two paths to the same goal, a contact in the CRM that a rep works. Cognism: its own database, phone-verified mobiles screened against 15 Do Not Call and TPS lists, one credit per revealed contact, exports 25 records at a time, quote only with 5 seats per package (Vendr median $32,750 a year from 94 purchases). Prospector: Clay's waterfall across 200+ providers on your Clay account, one button for the rep, one click to the CRM, $45 per rep per month billed annually. All checked 2 October 2026.
Fair to them first
What is Cognism best at?Calling Europe, with the paperwork done.
If your reps phone buyers in London, Paris or Munich, Cognism is the vendor to measure others against on the data that matters most there: mobiles. It runs a team of researchers who validate mobile numbers by hand, which it sells as Diamond Data, and it scrubs its records against "15 major Do Not Call and TPS lists," naming registers from the UK's TPS and CTPS to Germany, France, Spain and Sweden. Vendr's own comparison sums up the reputation: "Strong EMEA coverage." On G2 it holds 4.5 out of 5 across 1,371 reviews.
The compliance work is real, not a badge. Cognism's compliance page says it notifies business contacts "of their inclusion in our database within GDPR timeframes," holds SOC 2 Type II, ISO 27001 and ISO 27701, and generally keeps the data inside the European Economic Area (cognism.com/compliance). It is also honest about the limit: each party "acts as an independent controller," and Cognism recommends "customers seek legal advice prior processing and using the data." For a European sales floor, one vendor carrying that file is worth paying for.
The trade-offs are the ones its own terms set. There is no list price, each package starts at 5 seats, and the fair-usage policy caps each user at 2,000 records viewed and 2,000 exported a month, 25 records at a time. Reviewers on G2 name the same two things: price, and coverage that thins outside Europe. None of that makes the data worse. It makes Cognism a strong buy for a team calling Europe and a poor fit for a 12-rep team that already pays for Clay.
Why buyers compare
Why are Cognism customers looking at Clay and Prospector?One shelf, a seat for every rep.
The question is rarely whether Cognism's European mobiles are good. It is whether one database is still the right shape of purchase once a GTM engineer is building in Clay.
One shelf, when Clay asks many.Cognism returns what is in Cognism. A Clay waterfall asks provider after provider until one returns a verified email or phone, and a team on Clay already pays for that reach. For US-heavy or mixed lists, one European-first shelf is a narrow bet.
A quote, not a price.There is no list price to plan against. Vendr's range runs from $16,585 to $88,449 a year, and the packages start at 5 seats, so a small team pays for headcount it may not have. The full breakdown is on Cognism pricing.
Seats for reps who mostly need the account in front of them.A Cognism seat opens the whole database. Many reps only need the contacts for the lead or account on screen, which is what a Clay table, run from that page, returns.
The list after the export.Cognism meters reveals. Whether the contact was worked, and how it ended, sits outside the product. Leaders on Clay ask Prospector to show that per list.
Prospector, for teams on Clay
What does Prospector do that a Cognism seat does not?You build it. Reps run it. Everyone sees it work.
Prospector is the rep side of Clay. Your GTM engineer builds the tables once, person enrichment, the buying committee for an account, the new-logo list for a campaign, and each becomes a flow a rep picks from a Push menu. A rep on a LinkedIn profile, a company's website or a HubSpot, Salesforce or Pipedrive record presses one button, and your Clay table runs on your own Clay account. In Sales Navigator, reps add leads to a prospect list and push the list to a Clay table. Your logic stays yours: waterfalls, tiers, tags and sequence variables. The engineer stops being the list desk.
Before anything syncs, the rep sees whether the person already has a CRM record, who owns it, and whether they were prospected before, so two reps do not work the same buyer. One more click sends the contact to HubSpot, Salesforce or Pipedrive with the field mapping Ops set once. Reps never log into Clay, and they do not need a database seat of their own to build lists.
Then the part a Cognism export does not show. A sales leader sees every list found, worked and closed, rep by rep, and every lead ends the way your process says: Qualified, Recycled or Disqualified. When a leader can see what the tables produced, the Clay budget grows. The full loop is on the sourcing use case, and the rep's view is on Prospector for reps.
Prospector costs $45 per rep per month, billed annually, which is $540 a rep a year and $5,400 a year for ten reps, and you can buy it for one rep. It runs on the Clay plan and credits you already pay for. There is no free trial yet. It starts with a demo on your own Clay account, and the details are on the Prospector page.
Choose something else when the job looks like this
No Clay and no one to build in it.Prospector runs only on Clay. Without a GTM engineer, a database a rep can use on day one is the faster start: Cognism for Europe, or Apollo for a US-heavy list.
European mobiles with the compliance file attached.If your reps live on the phone into the UK and EU and legal wants one vendor answering for Do Not Call screening and GDPR notices, Cognism does that and Prospector does not try to.
Reps who live in an AI chat.If your reps work inside ChatGPT or Claude, Clay's own MCP brings Clay there, governed by Ops.
Run your Clay table from LinkedIn.
A demo on your own Clay account. Bring the table your reps ask for most often.
Cognism vs Prospector: which should you choose?Decide by where you call, and whether you run Clay.
If you have no Clay and your reps call into the UK and Europe, Cognism is the best pick. If you run Clay, Prospector is the best pick: Clay plus Supered is the best way for a sales team to prospect, because GTM engineers build in Clay and reps never open it.
Choose Cognism if
Your buyers are in Europe and you call them. Phone-verified mobiles and Do Not Call screening across 15 registers are the reason to buy it.
You want one vendor to answer for compliance. GDPR notices, SOC 2 Type II, ISO 27001 and 27701, data kept inside the EEA.
You have no Clay and no builder. A rep with a seat can search, reveal and export on day one, on a contract you negotiate.
Choose Prospector if
You already run Clay. Every rep runs your tables from LinkedIn, company sites and the CRM record, with no Clay login.
You want lists you can follow. Found, worked and closed for each list, rep by rep, with no duplicate work.
You want a price you can read today. $45 per rep per month, billed annually, from 1 rep, on the Clay you already pay for.
Some teams keep both. Cognism stays the source for European mobiles, and Clay runs everything else through Prospector. A GTM engineer can also call Cognism's API from a Clay table on your own Cognism contract, so its results land in the same waterfall reps run.

Switching, or using both
How do you move from Cognism seats to Clay and Prospector?Keep what works, move the front door.
You do not have to drop Cognism on day one. The gentler path is to run Clay next to it, see what the tables produce, then decide at renewal.
Turn the tables into buttons.An admin connects Clay inside Supered, and each table or custom workflow becomes a flow reps pick from the Push menu. Start with the Supered Clay template or bring your own tables.
Decide where Cognism sits.Cognism is not in Clay's marketplace, but its Enrich API returns a free preview and its Redeem API charges one credit per contact, never twice for the same person. A GTM engineer can call it from a Clay table for European numbers only. Check your Cognism contract first; the build is on Clay vs Cognism.
Set the CRM mapping once.Ops maps fields for HubSpot, Salesforce or Pipedrive, and every sync after that is one click.
Watch the lists, then decide at renewal.With found, worked and closed per list, you can see what the tables produce before the Cognism renewal. Vendr buyers report bigger discounts when a competitor is in the room.
What else should a Cognism buyer look at?The rest of the shortlist.
If neither Cognism nor Clay plus Prospector fits, these are the other names buyers put next to Cognism. Each has a full head-to-head on our blog.
Apollo.One database with a Chrome extension and built-in sequences, self-serve. The usual pick for smaller US-heavy teams with no Clay. Cognism vs Apollo.
ZoomInfo.Sold on a quote like Cognism, with a deeper North American database, intent and AI agents. Cognism vs ZoomInfo.
Lusha.A lighter database and extension with self-serve plans, and it runs as a step inside Clay. Lusha vs Cognism.
Kaspr.Owned by Cognism: a LinkedIn extension for individual reps and small teams, from $49 per user per month billed annually (kaspr.io, checked 2 October 2026). Kaspr alternatives.
LinkedIn Sales Navigator.Not a contact database: it finds people, it does not give you their email or phone. It pairs with Prospector, which turns a Navigator list into enriched CRM contacts. Cognism vs Sales Navigator.
For teams on Clay, yes. Prospector brings no database of its own: it runs your Clay tables, Clay's waterfall across 200+ providers, from LinkedIn profiles, Sales Navigator, company websites and HubSpot, Salesforce or Pipedrive records, then syncs to the CRM in one click. For teams with no Clay that call into Europe, it is not a substitute; Cognism is the better buy.
How much does Cognism cost compared with Prospector?
Cognism publishes no prices: its Standard and Pro packages each include 5 seats and are sold by quote, at one credit per revealed contact. Vendr's median Cognism buyer pays $32,750 a year, across 94 purchases (checked 2 October 2026). Prospector costs $45 per rep per month, billed annually, from 1 rep, and runs on the Clay plan and credits you already have.
Is Cognism in Clay's waterfall?
Not as a native integration. On 2 October 2026, Clay's integration page for Cognism returns Not Found, while Clay lists 200+ other providers. A GTM engineer can still call Cognism's API from a Clay table with your own Cognism account, where the Redeem API charges one credit per contact. Check your Cognism contract before you build it.
Do reps need a Clay login or a Cognism seat to use Prospector?
Neither. Prospector runs on your company's Clay account and Clay credits, so the team needs Clay, but reps never log into it. They press a button inside the Supered Chrome extension where they already prospect.
Does Prospector scrape LinkedIn?
Prospector works within LinkedIn's terms and does not copy search results in bulk; the contact data comes from Clay's waterfall on the customer's Clay account. In Sales Navigator, reps add leads to a prospect list and push the list to a Clay table.
Which CRMs does Prospector work with?
HubSpot, Salesforce and Pipedrive. Ops sets the field mapping once, reps sync in one click, and before they do, they see the matching CRM record and whether the person was worked before.
