Cognism vs apollo.io: which B2B data platform is right for you? Last updated: September 20, 2026 Cognism wins on data quality and compliance; Apollo wins on price and all-in-one features. If you're in Europe or have strict GDPR requirements, Cognism is the safer choice. If you're an early-stage team that needs prospecting, sequencing, and enrichment in one affordable tool, Apollo is hard to beat. The decision comes down to your geography, compliance obligations, and whether you need a dedicated data layer or a full sales engagement platform. Key takeaways * Cognism has stronger GDPR compliance and European mobile coverage; Apollo has a larger overall database and a free tier. * Apollo's pricing starts at $0 (limited) and scales from ~$49/user/month; Cognism quotes custom contracts, typically $15,000-$30,000+ per year for small teams. * Apollo includes built-in email sequencing and dialer; Cognism is a data layer that integrates with your existing stack. * For outbound-heavy SDR teams targeting European accounts, Cognism's phone-verified mobile numbers are a meaningful edge. * Neither tool tells you which companies are actively using your competitors - for that, you need a different approach entirely. What is Cognism and who is it built for? Cognism is a B2B data platform focused on contact and company data, with particular strength in European and UK markets. It provides verified mobile numbers, email addresses, and firmographic data, and is built around compliance - it maintains its own do-not-call suppression list and is designed for teams that need to demonstrate GDPR and CCPA compliance to legal or procurement. The typical Cognism customer is a mid-market or enterprise sales team running high-volume outbound, often with a legal team in the loop. They care more about data accuracy - especially phone numbers - than about having a built-in sequencing tool. Cognism integrates with Salesforce, HubSpot, Outreach, and Salesloft rather than competing with them. Cognism's Diamond Data tier includes phone-verified mobile numbers, where a human has confirmed the number is correct and belongs to the right person. This is meaningfully different from data that's simply scraped and matched, and it explains why Cognism commands a premium price. What is Apollo.io and who is it built for? Apollo.io is a full sales intelligence and engagement platform - it combines a 275M+ contact database with built-in email sequencing, a dialer, LinkedIn integration, and AI-assisted workflows. For a team that doesn't want to stitch together a data tool, a sequencer, and an enrichment layer, Apollo handles all three. Apollo's sweet spot is early-stage and growth-stage SaaS companies where the sales team is small, budget is limited, and people need to move fast without an ops team configuring integrations. The free tier gives you 10,000 email credits per month and access to the full prospecting interface, which makes it one of the lowest-friction ways to get started with outbound. The trade-off is data quality. Apollo's database is large, but mobile number accuracy - especially outside North America - lags behind Cognism. Salesloft's research on B2B data accuracy found that mobile number accuracy varies by as much as 40 percentage points depending on the provider and the region being targeted. For US-focused teams doing email-led outreach, this gap is manageable. For European cold-call campaigns, it matters a lot. How does Cognism's data quality compare to Apollo's? Data quality is where the two platforms diverge most sharply, and it's the single most important factor for SDR teams running phone-based outreach. Cognism's flagship differentiator is phone-verified mobile numbers. For the Diamond Data tier, a real person has called and confirmed the contact before the number enters the database. The result is connect rates that Cognism customers consistently report as materially higher than industry averages - particularly in the UK and Europe where mobile number churn is high. Apollo's mobile number coverage is broader in raw volume but lower in verified accuracy. Their strength is email: with 275M+ contacts and a strong email verification layer, Apollo is one of the better tools for email-first outbound. For teams running email sequences rather than call-first workflows, this is often sufficient. "We switched from Apollo to Cognism for our UK team specifically because connect rates on cold calls had dropped below 4%. Within two months on Cognism Diamond Data, we were back above 11%." - Head of Sales Development, 60-person B2B SaaS, London For European B2B data specifically, Cognism also maintains TPS (Telephone Preference Service) and CTPS suppression lists, which is a legal requirement for cold calling in the UK. Apollo does not natively handle this, which creates compliance risk for UK teams. How does Cognism pricing compare to Apollo pricing? Pricing is where Apollo has a clear structural advantage, especially for smaller teams. Apollo pricing. * Free: 10,000 email credits/month, basic sequences, limited exports * Basic: ~$49/user/month (billed annually) - unlimited email credits, full sequences * Professional: ~$79/user/month - advanced analytics, AI features, more dialer minutes * Organization: ~$119/user/month - custom permissions, SSO, advanced reporting Cognism pricing. Cognism does not publish pricing. Contracts are sold annually, typically with a platform fee plus a data credit package. Based on publicly reported figures and user reviews on G2, most small teams (2-5 seats) pay $15,000-$30,000 per year for a base package. Diamond Data adds cost. For enterprise teams, annual contracts routinely exceed $50,000. The gap is significant. A 3-person SDR team on Apollo Professional pays roughly $2,844/year. The equivalent Cognism contract would typically be 5-10x that. For early-stage companies, this is a real constraint - and it's the main reason Apollo dominates in smaller teams despite Cognism's data quality advantages. What features does each platform offer that the other doesn't? | Feature | Cognism | Apollo | | Phone-verified mobile numbers | | (Diamond tier) | | | | Built-in email sequencer | | | | | | Built-in dialer | | | | | | GDPR / TPS compliance layer | | (native) | Partial | | Free tier | | | | | | LinkedIn extension | | | | | | CRM enrichment | | | | | | Intent data | | (via Bombora partnership) | | (native) | | AI-assisted outreach writing | | | | | | Technographic / competitor filters | Limited | Limited | One gap that neither platform fills well: identifying companies that are actively using a specific competitor. Both Cognism and Apollo offer technographic filters - you can filter by tech stack categories like "CRM" or "marketing automation" - but neither gives you a clean, real-time list of companies confirmed to be using a named competitor product. If competitor targeting is a core part of your ICP strategy, you'll need a dedicated tool alongside either platform. Stealery is built specifically for this: you search a competitor's name and get a filtered list of every company confirmed to be using it, ready to hand off to your sequencer. Which platform is better for SDRs doing high-volume outbound? The answer depends on your motion and your market. Choose Cognism if: * You're targeting UK or European accounts and cold calling is part of your workflow * Your company has legal or procurement requirements around data compliance * Connect rate on dials is a KPI you're measured on - Diamond Data's accuracy justifies the cost * You already have a sequencing tool (Outreach, Salesloft, Apollo sequences) and just need clean data piped in Choose Apollo if: * You're targeting North American accounts where email-first outbound is the primary motion * You need sequencing, dialing, and data in one tool without budget for a full stack * You're an early-stage team that needs to move fast and can't commit to a $20,000+ annual contract * You want AI-assisted email writing baked into the same workflow Gartner's analysis of the sales technology market consistently shows that data accuracy and workflow integration are the two most cited reasons teams switch between B2B data providers - not price. That said, price is almost always the reason early-stage teams don't upgrade in the first place, which explains why Apollo has grown faster in the sub-50-employee segment while Cognism dominates mid-market. Can you use both Cognism and Apollo together? Yes, and some teams do - particularly those that use Apollo for US prospecting and Cognism for UK/EU, or those that use Apollo's sequencing layer while feeding it data from Cognism. The duplication cost is real, but for teams where both markets matter, it's sometimes the pragmatic answer. A more common pattern is to use Apollo as the primary platform and supplement it with Cognism exports for specific campaigns where mobile number quality is critical - for example, a targeted outbound push on a named accounts list where you're cold calling VP-level contacts in the UK. You pay Cognism for verified data on that specific cohort rather than running a full Cognism contract. If your team is evaluating the full stack, it's worth mapping out your outreach motion first: what percentage of your pipeline comes from cold calls vs cold email vs LinkedIn? If it's mostly email, Apollo alone is likely sufficient. If cold calling is 40%+ of your activity and you're in Europe, Cognism's accuracy premium pays for itself in connect rates.
