If you are comparing Cognism and Apollo, you are probably solving two problems at once. One is outbound performance in Europe. The other is a legal team asking whether the dataset you are about to buy is actually lawful to use on EU residents. These two questions have different answers for each tool, and the stacked price tag is 3-10x different.
I am George, founder of Leadpipe. I have sat on both sides of this decision with teams selling into the UK and DACH. This post is the straight comparison on GDPR posture, mobile coverage, pricing, and workflow, plus the option that shows up when you ask “where is the warmest pipeline actually hiding?”
Short answer. Cognism is usually the right buy for EU and UK outbound with compliance discipline. Apollo is the right buy for US-centric SDR teams that want one tool for list build, sequencer, and dialer. The GDPR gap between them is real, not marketing.

What is Cognism
Cognism is a London-headquartered B2B sales intelligence platform built to sell into Europe. The dataset runs around 400M profiles with heavy investment in UK, DACH, Benelux, Nordics, and France coverage. The signature product is “Diamond Data,” a human-verified mobile number dataset.
Strengths:
- EU and UK mobile coverage is the best in the category. If outbound dialing in Europe matters, Cognism usually wins here.
- GDPR-native posture. Notified-party model under Article 14, TPS (UK), CTPS (UK), DNC lists checked before export.
- Strong intent data via Bombora partnership on higher tiers.
- Clean CRM sync into Salesforce, HubSpot, and Dynamics.
- SDR-friendly Chrome extension and integrations with Outreach, Salesloft, and Apollo.
Weaknesses:
- Annual contracts, enterprise pricing. No monthly, no self-serve.
- US coverage is real but not as deep as ZoomInfo or Apollo at the same price.
- No built-in sequencer or dialer. You stack Outreach or Salesloft on top.
- Custom-quoted pricing slows procurement.
- Smaller EU companies and niche ICPs are still thin.
What is Apollo
Apollo is a platform that bundles a database (275M contacts, 73M companies) with a sequencer, a dialer, a meeting scheduler, and an AI writer. The pitch is consolidation: $49-$99 per seat replaces a separate database plus Outreach or Salesloft.
Strengths:
- Consolidation. List build plus sequencer plus dialer in one tool.
- Public pricing, monthly billing, fast self-serve onboarding.
- Strong US SMB and mid-market coverage.
- Chrome extension and native CRM sync.
- Low switching cost. SDRs productive on day one.
Weaknesses:
- EU mobile coverage is uneven. Cognism wins there.
- GDPR posture is legitimate interest plus customer-managed. TPS/CTPS handling is on you.
- Broad database, not deep. Decayed titles on niche ICPs.
- 90-95% email accuracy (claimed). Bounce on aged records runs higher.
- Sequencer is good enough, not category-leading.

GDPR posture, honestly
This is the real differentiator for EU-selling teams. Both vendors process personal data of EU and UK residents; they do it under different frameworks.
Cognism:
- Notified-party model. Article 14 notifications sent to EU and UK individuals whose data is in the database.
- TPS and CTPS checked on UK mobile numbers at export.
- National DNC lists honored across supported EU geos.
- DPA available, joint-controller or processor depending on configuration.
- Audit trail is defensible in a regulator review.
Apollo:
- Legitimate interest framework for processing professional contact data.
- DPA available, EU data governance documented.
- TPS and CTPS handling is the customer’s responsibility by default.
- Mobile suppression in DACH is narrower than Cognism.
- Posture works for most US-centric teams with an EU tail. Strict EU-first teams often find it thin.
Neither tool is non-compliant. They operate under different lawful bases and the evidentiary burden lands in different places. If your legal team wants the provider to carry more of the weight, Cognism is easier to defend. If your EU footprint is light and your team is comfortable managing lawful basis themselves, Apollo’s framework is usually acceptable.

Pricing
Cognism:
| Tier | Annual cost | Notes |
|---|---|---|
| Platinum | ~$15,000-$25,000/yr | Core platform, Diamond Data, intent |
| Diamond | ~$25-45K/yr | Higher volume, advanced permissions |
| Enterprise | ~$40-80K/yr | Full API, Dynamics, governance |
Apollo:
| Tier | Price | Seats | Notes |
|---|---|---|---|
| Free | $0 | 1 | Limited credits |
| Basic | $49/user/mo | 1+ | Sequencer, mobile access |
| Professional | $99/user/mo | 1+ | AI writer, dialer, reports |
| Organization | Custom | 5+ | SSO, advanced controls |
Rough side-by-side for a 10-seat team:
| Scenario | Cognism (mid) | Apollo Pro | Apollo + Outreach |
|---|---|---|---|
| Sticker (annual) | ~$25,000 | ~$11,880 | ~$28,000 |
| Sequencer | Not included | Included | Outreach bundled |
| EU dialing coverage | Strong | Moderate | Moderate |
| Monthly billing | No | Yes | No (annual) |
Price-per-seat is misleading. For a US SMB SDR team that never dials the UK, Apollo costs half as much. For a team running outbound into DACH and the UK, the extra cost of Cognism is usually justified by connect rate alone.
Workflow fit
| Workflow | Cognism | Apollo |
|---|---|---|
| Build EU-compliant list of 1,000 contacts | Strong | OK |
| Dial UK mobile numbers at scale | Best-in-class | Moderate |
| Sequence cold email in same tool | No (integrations) | Yes |
| Run ABM with intent signals | Strong (Bombora) | Light |
| Enrich existing Salesforce contacts | Native | Native |
| Push to HubSpot lists | Native | Native |
| Route to Outreach / Salesloft | Native | Native |
| Self-serve trial | No | Yes |
If your motion is dial-first in Europe, Cognism plus a sequencer beats Apollo alone. If your motion is email-first in the US, Apollo’s bundle is hard to beat on price.
The scenario where each wins
Pick Cognism if:
- You sell into UK, DACH, Benelux, Nordics, or France as a primary market.
- Mobile dials are a core part of SDR motion.
- Legal or compliance is strict about GDPR posture.
- You already own Outreach, Salesloft, Apollo, or Instantly for sequencing.
- You want the provider to carry lawful-basis evidence, not you.
Pick Apollo if:
- Your ICP is US SMB or mid-market.
- You want list build plus sequencer plus dialer in one tool.
- You need a new hire productive on day one.
- You want monthly billing and easy cancel.
- Your EU footprint is a tail, not the main market.
Pick neither, at least not first, if your website gets meaningful traffic and you have not identified those visitors yet.
The third angle
Both Cognism and Apollo answer “where can I buy cold contacts to email and call?” That is still a legitimate question. It is no longer the highest-ROI question for most B2B companies in 2026.
If you are spending $25K on Cognism or $12K on Apollo without identifying the visitors already on your site, you are paying for cold while giving away warm.
Cold email reply rates have collapsed below 1% for most teams. Mobile connect rates in DACH are stressful even with Diamond Data. Meanwhile 97-98% of your B2B website visitors never fill a form. In EU and UK traffic especially, that hidden pipeline is the warm channel most teams ignore.
Leadpipe installs a pixel, deterministically matches B2B visitors against our own identity graph, and returns full person records: name, business and personal email, phone, LinkedIn, firmographics, 100+ attributes, daily refresh, 60B intent signals across 5M monitored websites.
Compliance posture. Leadpipe is CCPA compliant, GDPR aware (company-level default for EU and UK traffic, person-level requires affirmative consent), and registered as a data broker in CA, TX, VT, and OR. DPA available, subprocessor list published. SOC 2 Type II readiness is in progress.
In US B2B traffic, we see 30-40%+ match rates at the person level. Our independent accuracy test across 75,000 visitors over 120 days put Leadpipe at 8.7/10 for deterministic identification.
Pricing. $147/mo for 500 identifications on Pro, $299/mo for 1,500 on Growth (about $0.20 per fully enriched warm lead), $599/mo for 5,000 on Scale. Month-to-month. For an EU-selling team that is roughly 2% of a Cognism Diamond tier, on warm leads who came to you.
For the positioning argument see midbound, replacing cold outreach data and the death of the lead form.
Our verdict
Cognism for EU and UK outbound with compliance discipline. The mobile coverage and the GDPR framework are worth the annual contract if Europe is your market.
Apollo for US SMB and mid-market SDR teams that want one tool for the whole motion. Price is hard to beat if the bundle actually fits.
For the warm channel hiding in your own traffic, use a tool built for that. Buying cold data before you identify your warm visitors is the most expensive inversion I see in 2026 GTM stacks.
