Key takeaways:
- Apollo is an all-in-one prospecting and engagement platform with transparent per-seat pricing, from a free plan up to $119 per user per month.
- Cognism is a data-only provider sold by custom quote, strongest on GDPR-compliant European contacts and phone-verified mobile numbers.
- Apollo wins on budget, breadth, and self-serve access; Cognism wins on European coverage, mobile accuracy, and compliance.
- Pick Apollo if you want data plus outreach in one tool; pick Cognism if clean EMEA data feeds an outreach stack you already own.
Choosing between Apollo vs Cognism usually comes down to one question: do you want a single tool that finds contacts and emails them, or a specialist data source that plugs into the outreach stack you already run? Both promise more meetings booked. They get there in almost opposite ways.
Apollo bundles a contact database, sequencing, and a dialer at a price a solo rep can afford. Cognism sells verified data, mostly to teams selling into Europe, and leaves the sending to your other tools. This Apollo vs Cognism comparison weighs the two on data coverage, pricing, features, and engagement, so you can tell which one actually drives more leads for your team.
Apollo vs Cognism at a Glance
Here is the short version before we get into each dimension. The two tools overlap on the surface (both sell B2B contact data with a Chrome extension and CRM sync) but split hard on price, region, and how much of the outbound motion they cover.
Apollo | Cognism | |
|---|---|---|
Core approach | All-in-one prospecting + engagement | Data provider, no built-in sending |
Best region | North America, broad global | Europe (EMEA) and UK, plus North America |
Database (advertised) | 275M+ contacts, 70M+ companies | 440M+ contacts, 100M+ companies |
Mobile data | Standard, credit-gated on higher tiers | Phone-verified Diamond Data mobiles |
Pricing | Free, then $49–$119 per user/month | Custom quote, no public pricing |
Free plan | Yes, free forever | No (25-lead ICP sample only) |
Built-in outreach | Sequences, dialer, email | None (integrates with your tools) |
Buying process | Self-serve, sign up and go | Sales-assisted, annual contract |
Apollo is the flexible, low-friction option you can start today. Cognism is the higher-touch, data-first option you buy after a sales call. Which fits depends on where your prospects are and how you run outreach, so let's look at each tool on its own before comparing them head to head. You can start a free Apollo account to test its data yourself while you read.
What Cognism Does
Cognism launched in 2015 as a B2B data company focused on accuracy and privacy compliance. It sells contact and company data (emails, direct dials, mobile numbers, firmographics, and intent signals) through a web app, a Chrome extension, and a CRM connector. It does not send email or run sequences. You take the data and load it into whatever outreach or CRM tool you already use.

Its standout feature is Diamond Data, a set of mobile numbers that human operators dial and verify by hand before adding them to the database. Cognism also screens records against do-not-call registries across 15 countries, which lowers the legal risk of cold calling in regulated markets. That manual work is why teams selling into Europe tend to name Cognism first.
The trade-off is reach and cost. Cognism runs on annual contracts sold by quote, with no free plan beyond a 25-lead sample of your ICP. You commit before you see the full dataset, which is a bigger bet than signing up for a free tool.
What Apollo Does
Apollo also launched in 2015, but built outward instead of deep. It pairs a large contact database with a full engagement suite: multi-step sequences, a built-in dialer, email sending, and basic deal management. You can build a list, enrich it, and email it without leaving the tool.
*Apollo's homepage, apollo.io.*
That breadth, plus a free-forever plan and paid tiers from $49 per user per month, is why Apollo shows up on almost every "cheap prospecting tool" shortlist. A single SDR can run an entire outbound motion on one subscription. Data quality is decent for North America and improving elsewhere, though it leans on algorithmic verification rather than the manual phone checks Cognism runs.
Apollo's weak spots are the flip side of its strengths. Its deal-management features are thinner than a real CRM, its credit system confuses people at scale, and European coverage (especially mobile numbers) is the most common complaint. For a tool that tries to do everything, the data layer is the part that shows the seams. You can compare its data against your current source on the free Apollo plan before paying for a seat.
Data Coverage: Europe, Mobiles, and Compliance
This is the dimension that decides most Apollo vs Cognism debates, because the two tools are built for different maps.
Apollo advertises more than 275 million contacts and 70 million companies, with its deepest coverage in North America. Cognism lists over 440 million contacts and 100 million companies, and points its strongest data at Europe: roughly 50 million mobile numbers in the US and more than 120 million contacts across the region. If you sell into the UK, DACH, or the Nordics, that gap is what matters most.
Mobile Numbers and Connect Rates
Cognism's Diamond Data is the clearest technical difference. Because operators physically call each mobile before it enters the verified pool, the phone-verified set is smaller but far more likely to reach a real person. Cognism cites an independent study finding phone-verified numbers connect about three times as often as standard ones. Apollo provides mobile numbers too, but gates them behind credits on higher tiers and verifies them algorithmically, which is why cold callers in Europe report more dead numbers.
Why Compliance Is Part of the Data Question
Clean European data isn't only about connect rates. The UK's Information Commissioner's Office notes that while PECR's electronic-mail rules don't apply to corporate subscribers, UK GDPR still governs the personal data you process, including a contact's right to object to direct marketing (ICO guidance on B2B marketing). Cognism's do-not-call screening and documented, consent-based sourcing are built around that obligation, which matters if your legal team reviews your data vendor.
For North American prospecting on a budget, Apollo's coverage is more than enough and costs a fraction as much. For European mobile-heavy outbound where accuracy and compliance carry real weight, Cognism is the safer data source. Line up the tool with your territory and the choice gets simpler.
Pricing and Transparency
Pricing is where the two tools feel like different products entirely, and it drives the "Apollo vs Cognism pricing comparison" searches for a reason.
Apollo publishes its prices. You can read them, do the math, and buy a seat in minutes.

Cognism publishes nothing. Every plan routes to "talk to sales," and you get a number after a call and an annual commitment.

Plan | Apollo (per user, billed annually) | Cognism (annual, quote-based) |
|---|---|---|
Entry | Free forever (limited credits) | No free plan (25-lead ICP sample) |
Starter | Basic, $49/user/month | Standard: ~$15,000 platform fee + ~$1,500/user, ~$22,500/year for 5 seats |
Mid | Professional, $79/user/month | Pro: ~$25,000 platform fee + ~$2,500/user, ~$37,500/year for 5 seats |
Top | Organization, $119/user/month | Custom (scales by team size and add-ons) |
Apollo's monthly billing runs roughly 15–25% higher than the annual rates above, so the yearly commitment is the cheaper path if you're sure about the tool. Cognism's reported figures come from procurement data, not a public rate card, and renewals typically rise 10–15% a year. Intent data (via Bombora) and other add-ons stack on top, often at $200–$400 per intent topic.
The honest summary: Apollo can cost a single rep under $600 a year, while Cognism starts in the low five figures and climbs from there. One real anecdote captures the shock. In a thread on r/SaaSSales, a team weighing the switch from Apollo to Cognism for EMEA data was quoted "closer to 15K minimum" after budgeting only 3,000 EUR (an anecdotal data point, but a common one). If budget is the deciding factor, this dimension settles it outright.
Features and AI
Both tools have loaded up on AI, but they aim it at different jobs.
Apollo uses AI across the whole workflow: it writes email copy, scores and prioritizes leads, summarizes calls, and suggests next steps inside sequences. Intent data comes from a third-party source (LeadSift) and is available on paid plans. Because everything sits in one platform, the AI can act on your actual outreach, not just your list.
Cognism points its AI at the data itself. Features like AI Search and recommended leads help you build and refine target lists faster, and its Sales Companion surfaces accounts worth a look. Intent signals come from Bombora, but only on the higher Elevate tier or as a paid add-on, so intent isn't a given at every price point.
The pattern holds across the feature set. Apollo gives you more tools that are good enough; Cognism gives you fewer tools built around cleaner inputs. If you want an AI assistant that drafts and sends, Apollo has more surface area. If you want AI that sharpens who you target, Cognism's is tied to better underlying data. Neither is objectively smarter. Each is pointed at a different half of the job.
Engagement and Sequencing
Here the comparison is lopsided, and it's the clearest reason the two tools often sit in the same stack rather than competing.
Apollo runs the whole outbound motion. You build multi-step sequences across email and calls, dial from a built-in phone, track opens and replies, and manage the resulting deals, all in one place. For a small team, that means one login and one bill instead of stitching a data tool to a separate sender.
Cognism does none of this. It has no sequencing, no dialer, no email sending. It expects you to export or sync contacts into Outreach, Salesloft, HubSpot, or a cold-email tool and run the sending there. That's not a flaw so much as a design choice, but it's a real cost if you don't already own an engagement tool.
The reason built-in engagement matters more each year: buyers expect to be reached in more places. B2B buyers now use around ten channels across a single purchase, up from five in 2016, according to McKinsey's B2B Pulse survey. Apollo lets one tool cover email and phone out of the box; Cognism assumes you've built that layer elsewhere. So if you have no outreach engine yet, Apollo saves you a purchase, while Cognism only pays off once your sending stack is already in place.
Pros and Cons
No tool wins every row, so here's the balanced view of where each one helps and hurts.
Apollo's strengths are price, breadth, and access. It's cheap, it does prospecting and outreach in one place, and you can start free today. Its weaknesses are data depth (thin European mobiles, algorithmic verification), a credit system that trips people up at scale, and CRM features that don't replace a real CRM.
Cognism's strengths are data quality, European coverage, phone-verified mobiles, and compliance built for GDPR markets. Its weaknesses are cost (low five figures and up), the opaque quote-only buying process, annual lock-in, and zero built-in sending.
A pattern worth naming from real users: the two tools fail in opposite directions. On Reddit, a rep who ran Apollo for DACH prospecting found only "40% of the phone numbers actually worked," which pushed them to look elsewhere for accuracy (r/SaaSSales, anecdotal). Cognism buyers rarely complain about the data; they complain about the price and the contract. Knowing which problem you'd rather have points you toward the right tool.
Which Should You Pick?
Match the tool to how you sell, not to a feature checklist.
Pick Apollo if you're a startup, SMB, or solo SDR who needs data and outreach in one affordable tool, sells mostly into North America, and wants to start without a sales call. At $49 to $119 per user per month, it's the obvious first prospecting tool, and the free plan lets you test the data before you pay. You can spin up an Apollo account and run a real list in an afternoon.
Pick Cognism if you sell into Europe, depend on mobile connect rates, work in a compliance-sensitive industry, and already own an engagement tool to send from. The cost only makes sense at that profile, but for teams that fit it, the data accuracy pays back the premium.
If neither fits cleanly, the middle path is a data-workflow layer. A tool like Clay pulls from many providers at once and pays only for verified matches, which lets you keep Apollo for outreach while topping up European or mobile data on demand instead of committing to a full Cognism contract. Plenty of teams run exactly that hybrid: Apollo as the engine, a specialist source for the data Apollo misses.
How to Test Both Before You Commit
Don't decide on the demo. Run a small bake-off on your own accounts first:
- Build a list of 100 target accounts you know well, ideally in the territory you actually sell into. You'll judge both tools against the same names.
- Pull those contacts on Apollo's free plan. Export the emails and mobiles, send 20 test emails, and dial 10 numbers. Log the bounce rate and how many calls reach a real person.
- Request Cognism's 25-lead ICP sample for the same segment. Check the overlap: which mobiles Apollo missed, which of its emails bounced that Cognism got right.
- Price the gap. If Apollo covers 80%+ of your list well, the Cognism premium is hard to justify. If half your European mobiles are wrong in Apollo, the connect-rate lift may earn back the quote.
Running the numbers on your real ICP beats any feature grid, because coverage varies wildly by industry and region. Whichever you choose, decide based on territory and budget first. Those two factors settle most of these decisions before features ever enter the conversation.
