Apollo vs Cognism: Which Should You Choose?

Apollo and Cognism sit in the same category. Both license a B2B contact database, wrap outreach features around it, and want to be the data layer underneath your outbound.

This comparison covers entry pricing, contract terms, usage metering, and what buyers report about data quality.

What is Apollo?

Apollo is a B2B contact database with sequencing, a dialer, and enrichment bundled into one per-seat subscription. It’s the default self-serve entry point into the data category. Third-party reports put its database at 230M to 275M contacts.

The commercial mechanism is a shared credit pool. Every reveal costs a credit whether it’s an email or a phone number. Apollo pools credits across the team, and they expire at the end of the billing cycle. Teams choose it for convenience on one bill and one login rather than for best-in-class data.

Pros

• Free plan you can test coverage on: You get the contact database, basic filters, and the Chrome extension, so you can check your ICP before spending a dollar.
• Everything on one bill: Sequencing, a built-in dialer, intent topics, waterfall enrichment, and email warmup all ship from $49 per user per month on annual billing.
• Intent topics come bundled: Paid tiers include 6 intent topics rising to 12 at the top tier, so intent sits inside the seat price rather than arriving as a separate license.
• Filter depth you can build a real ICP with: More than 65 attributes cover title, seniority, headcount, geography, tech stack, hiring signals, and funding, with Boolean logic on title fields. Narrow segments come out of the search rather than out of a manual cleanup pass.

Cons

• Data accuracy draws consistent complaints: Multiple independent reviews report real-world accuracy around 65–70% and bounce rates of 15–25%. Several conclude that teams need a second verification tool.
• Credits expire with no rollover: Apollo’s credits FAQ states plainly that credits don’t carry into the next cycle or on renewal. On annual billing, Apollo grants the full year upfront, and you forfeit whatever’s unused at the 12-month mark.
• International dialing sits behind a 3-seat minimum: Apollo gates the international dialer, custom reports, and SSO to the top tier. That tier has no single-seat option, so its real entry price is $357 per month.

Pricing

Apollo runs a free plan plus 3 paid tiers on annual billing: Basic at $49 per user per month, Professional at $79, and Organization at $119 with a 3-seat minimum. Monthly billing adds 20–25% depending on the tier, and every paid tier is self-serve with no demo required to buy. Credits are the variable worth watching, since they expire each cycle and Apollo doesn’t publish top-up rates.

What is Cognism?

Cognism is a UK-based B2B contact data provider that competes on compliance and accuracy rather than volume. It licenses a contact database, layers Bombora intent on top, and sells Diamond Data, its human-verified mobile numbers, as the reason to pay for the higher tier. 

The commercial model is unusual for the category: A platform fee plus per-user licenses, with unlimited views inside contractual access limits and no credit meter running in the background. Its center of gravity sits on the data layer, so most teams pair it with a sequencer they already own.

Pros

• Diamond Data changes connect rates: Human-verified mobile numbers are the most cited reason buyers move up a tier. G2 reviewers generally report 2–3x connect-rate improvements on UK and EMEA contacts.
• Unlimited views instead of a credit pool: Cognism doesn’t meter views, and exports run up to 25 records at a time inside your contractual access limits. Nobody on your team spends the last week of the month watching a counter, and budget conversations stop being about credit top-ups.
• GDPR posture is built into the product: A GDPR-first build plus UK ICO registration, which comparative analyses note runs deeper than most US-first databases carry. For teams prospecting into the EU, that’s the purchase rationale.
• Hitting a limit blocks access rather than billing you: Exceeding contractual limits stops the workflow rather than generating a surprise invoice, which keeps the annual number predictable. Cognism doesn’t publish the fair-use ceiling, so it’s worth asking where it sits before signing.

Cons

• No free tier or self-serve trial: A 25-lead sample exists, but it runs through the sales process, so you can’t check coverage for your ICP before a conversation.
• The platform fee lands before any seat cost: Buyer-reported figures put the entry platform fee near $15,000 a year, so a single user lands around $16,500 before you add anything else.
• Coverage thins outside Europe: Multiple independent reviews report weaker US coverage and uneven Diamond coverage, with buyer sentiment notably more mixed among US-only teams.

Pricing

Cognism publishes no prices, so every figure in circulation is buyer-reported. Reported structure is a platform fee plus per-user licenses across 2 tiers, near $15,000 a year plus $1,500 per user at entry, and near $25,000 plus $2,500 per user above it. Contracts are annual and paid upfront. Buyers report onboarding at $500 to $1,500, Bombora intent topics at $200 to $400 each, and renewal increases at 10% to 15%.

Apollo or Cognism: Which should you choose?

Both tools hand you contact data and leave the outreach strategy to your team. 

The decision turns on where your buyers sit and which channel you lead with. It also turns on how much you’ll commit before you’ve watched the data perform.

Choose Apollo if…

You want to test data coverage before you commit budget

The free plan gives you the contact database, basic filters, and the Chrome extension, so you can run your ICP through it and see what comes back. That matters more than it sounds, because coverage for a narrow segment is the thing no pricing page can tell you. Basic and Professional both bill monthly, so you can run a real quarter without signing an annual deal.

Professional carries a 14-day trial on top of that. Apollo for Startups takes 50% off annual Basic or Professional for the first year, capped at 5 seats for companies with 20 or fewer employees. The evaluation costs you time rather than budget.

You need data, sequencing, and a dialer on a single bill

Apollo bundles the whole motion into one per-seat subscription. Your team works from one login instead of stitching a database to a sequencer to a calling tool. The entry tier includes waterfall enrichment and email warmup. Those are 2 line items a small team would otherwise buy separately.

Professional removes the sending caps rather than raising them. You get unlimited mailboxes, unlimited daily sends, and the US dialer with call recording. For a team of 3–10 people selling into the US, that consolidation is the whole purchase rationale.

Choose Cognism if…

Cold calling into the UK and EMEA is your main channel

Diamond Data is human-verified mobile numbers. G2 reviewers generally report 2x to 3x connect-rate improvements when they switch to it, concentrated on UK and EMEA contacts. If connect rate is the number your quarter turns on, that’s a direct line to pipeline rather than a feature comparison. European coverage draws consistently strong reviews across G2, Capterra, and Reddit.

It’s the reason EU-focused teams keep renewing. Cognism doesn’t meter views inside your access limits, so a heavy calling motion doesn’t burn through an allocation halfway through the month. The trade you’re making is budget certainty for data certainty.

GDPR compliance is a procurement gate

Cognism is built GDPR-first and holds UK ICO registration. That’s a real distinction when legal reviews the contract before your sales team sees the tool. For companies prospecting into the EU, that posture is the purchase rationale rather than a compliance badge on the footer.

The commercial model helps here too. Hitting a contractual limit blocks access instead of generating an overage invoice, so the annual spend stays predictable for finance. Support quality shows up alongside data quality as a recurring strength in reviews, and that matters when compliance questions land mid-contract.

Why AiSDR might be a smarter third option

Apollo and Cognism both sell you the raw material. Your team still decides who to target and works out what to say. Then it builds the sequence and handles every reply that comes back.

AiSDR is built for the team that wants the outcome instead of the ingredients. It measures success in meetings that show up rather than emails sent.

Ami AI Strategist

Neither tool tells you what campaign to run. Ami does that first. It reviews your offer, your CRM data, and your past campaigns.

Then it suggests specific audiences and niches worth going after, based on your goals. AiSDR has trained Ami on more than 20,000 campaigns. The plays it proposes come from what has already worked rather than from a blank canvas.

The practical version is short. Ami analyzes your site and builds a campaign in about 20 minutes, and you review and launch in 2 clicks. Around 80% of AiSDR customers use it instead of building campaigns by hand, and campaign execution runs about 6x faster than doing it manually.

For a small team that has never had a dedicated outbound strategist, that’s the gap it closes. 

Live AI search

Both tools ask you to trust that a licensed database is still accurate, which is where the accuracy complaints and the regional coverage gaps come from. AiSDR builds the list on demand instead. Live AI search finds prospects when you need them, with contact data valid as of today. Nothing decays on a shelf between refreshes.

It also handles the audiences a filter set can’t reach. You describe who you want in plain text and the AI goes and finds them. That works for ultra-niche ICPs that don’t map to a firmographic dropdown.

Ami decides what to look for and Live AI search goes and finds it. The 2 run as one system rather than as separate steps. There’s no credit counter to watch and no allocation to forfeit at renewal, because you aren’t paying for records that were collected months ago.

Intent and CRM data

Timing is the part a contact record can’t give you. AiSDR pulls website visitors, LinkedIn profile visitors, LinkedIn social engagement, and LinkedIn keywords together as signals in one place. Outreach fires when someone shows a public, verifiable sign that they have the problem you solve.

The CRM side runs in both directions. Through its HubSpot and Salesforce integrations, AiSDR processes, scores, and enriches your account data for inbound and outbound leads alike. It then reaches out only to accounts the AI has qualified. Enrichment and qualification work against any publicly available web data.

The research behind a message is something a human could go verify. That’s why the outreach reads as timely rather than intrusive.

AiSDR customers convert at 1–3%, against an industry average of 0.1–0.5%. That works out to 1–3 meetings per 100 targeted leads.

Campaign Builder with multichannel conditional sequencing

Data doesn’t send anything, and a sequencer you bring yourself still needs someone to run it. AiSDR’s Campaign Builder covers email, LinkedIn messages, connection requests, InMails, and calls in a single flow. Text, voice notes, AI video, and memes are available as mediums inside the same sequence.

Conditional logic sits behind a drag-and-drop interface, so you can build something simple or something layered without needing to write prompts for it. The AI handles replies, objections, follow-ups, and unsubscribes until the goal is met.

Behind the scenes, AiSDR procures and configures lookalike mailboxes, runs continuous warmup, and tests deliverability on a schedule. That’s the work agencies charge thousands for.

Pricing starts at $250 per month on the Solo plan, and all 3 plans are self-serve. Contracts run quarterly and bill monthly, so you’re committing a quarter rather than a year.
