Cognism vs Apollo.io: Databases

sc_Redesign graphic 9

Apollo.io does not state what regions its database covers. When answering the question on its site, the response is to sign up for a free account and run a search.

Cognism’s dataset offers the most complete coverage in the EMEA. The tool has EU and US research teams, making it a great option for anyone looking to find highly-targeted global leads, including NAM and APAC.

Moreover, quality is of utmost importance to Cognism, with phone-verified numbers, the most complete data in Europe and leading mobile number coverage in the United States.

We interviewed Marc Parsons, SDR Team Lead at OneUp Sales, to discover why he chose Cognism over Apollo.io. He said:

“Firstly, we trialled Apollo using a test data sample which didn’t produce adequate results. We proceeded to evaluate ZoomInfo but found the data to be too US-centric. This didn’t fit our ICP of targeting UK companies.”

“The SDRs have pulled data from Cognism for every demo booked. For every deal closed, the AEs have used the database to pull relevant contact details to influence the deal.” 

“Overall, 60% of our deals have come from the team pulling a number from Cognism.” 

Where do Cognism and Apollo.io get their data?

Apollo openly admits to ”scraping millions of records monthly”. On top of that, they “use machine learning algorithms and use a proprietary data network of contributors”.

According to Apollo.io’s T&Cs, Apollo’s customers grant Apollo a “perpetual and irrevocable licence” to access and use, share, sublicense, display, copy, publish and distribute any customer-submitted data. 

This means that by connecting your CRM to Apollo’s software and using its services, you’re adding data to their database.

In contrast, at Cognism, your customer data stays with you.

Apollo has a 7-step email verification process, while Cognism uses 16 steps to verify emails. Apollo mentions verification via data contributor networks, public data crawling, and third-party data providers. 

Unlike Apollo, Cognism excludes personal emails from its email database for lower legal risks and to ensure you are only contacting a notified B2B email database. However, we recommend testing a data sample from both providers to check their accuracy.

Cognism gathers data via its proprietary sources and fills in the gaps from third-party data providers, publicly available sources, manual research and strategic partnerships - the tool does not use customer data to supplement its database. 

Cognism ensures up-to-date B2B data via machine learning processes that check millions of data points daily. A team of in-house researchers verifies the data, ensuring accuracy and compliance. This stringent verification process applies to Cognism’s entire database.

However, Cognism takes data verification to the next level through its exclusive data asset, Diamond Data®.

Diamond Data® comprises phone-verified mobile numbers that make it three times more likely that you’ll connect with your ideal customer. The team phone verifies mobile numbers and includes contacts specifically requested by customers leveraging the Diamonds-on-Demand® service—Apollo does not provide a similar service. 

Diamond Data® allows sales teams to connect with 87% of prospecting lists. Companies are seeing a 54% increase in mobile coverage, and ROI is increasing due to 70% of outbound meetings booked from Cognism mobiles.

Apollo.io versus Cognism: Compliance

Apollo claims CCPA and GDPR compliance. The vendor has recently started checking DNC lists in the UK and US (the feature is in Beta for new direct dial requests), compared to Cognism, which checks lists in 12 countries.

Another difference between Apollo.io and Cognism is that Apollo charges credits if a phone number is revealed on a DNC list.

On the other hand, Cognism’s licence model ensures you don’t waste credits on DNC numbers.

If data compliance is one of your top priorities, we recommend you study Apollo.io’s Terms of Service.

Cognism is GDPR and CCPA compliant and scrubs all mobile numbers against:

  • TPS/CTPS lists in the UK.
  • Do-Not-Call lists in the USA, Canada, Australia and European countries, including Germany, France, Spain, Ireland, Belgium, Croatia, Portugal, Sweden and more.

If a number is marked as TPS or DNC, it means that the user has opted out of receiving unsolicited phone calls by applying to the national do-not-call registry. 

Cognism allows admins to choose whether to hide or show contacts on DNC lists from reps. Meaning that its customers have complete confidence in the legality of its outreach.

The platform follows these compliance-based actions: 

  • A stringent B2B data verification process. 
  • Ensures all data is legally sourced and of the utmost quality.
  • Provides users with a notified database.

Customers like Corporate Traveller praise Cognism for its commitment to compliance:

“Compliance is a major factor when considering how best to access prospect data, and choosing a partner that can combine GDPR conformity, great coverage of the UK market and deliver constantly updated qualified mobile numbers and contact details meant Cognism was the right choice for us.”

Remember, choosing a provider serious about compliance isn’t only about ensuring you don’t incur a hefty fine but also that your teams can prospect confidently. 

Henderson Scott saw the effects of having quality, compliant data when they invested in Cognism: 

“Cognism is our comfort blanket when it comes to compliance.” 

“Whenever a prospect asks where we get their data from, we can confidently say that we’ve sourced their information from a reputable ISO 27001 and SOC Type II certification data company.” 

“With Cognism, you aren’t snowing yourself under with ICO complaints. I couldn’t recommend it enough.”

Apollo.io vs Cognism: Usability & integrations

Apollo.io reviews mention that the desktop platform is easy to use, with good filters and a simple search dashboard.

Cognism integrates with leading CRMS and customers speak highly of the interface, usability and support:

Finn D.

“I want to focus on the two strongest areas where Cognism is the strongest. Firstly, its ability to get more accurate mobile phone numbers and the direct office numbers that any other tool on the market. Secondly, is its integration with both our CRM, Salesforce and Sales Enablement Platform, Outreach”

“The GDPR-compliant and accurate data Cognism provides for us really helps shorten our sales cycles and allows us to get B2B data at the click of a button for whoever we would like to contact.”

FAQs about Apollo.io vs Cognism

Cognism and Apollo.io source intent data but from different providers. Cognism partnered with the industry leader Bombora, while Apollo uses LeadSift. 

LeadSift uses contact and account intent, custom search terms and public web scraping. 

Unlike LeadSift, Bombora’s intent data isn’t scraped. It’s consent-based and collected from a cooperative of 5,000 B2B sites, where B2B buyers actively research a topic when they’re ready to make a purchase. 

  • It considers the historical baseline or typical content consumption when calculating intent.
  • It considers the context and the length of each interaction.
  • Bombora’s dataset is 70% exclusive.

Combining Bombora’s buyer intent with Cognism’s contact data, you can find, prioritise, and connect the right prospects at the right time. It shortens the sales cycle, improves targeting, and creates a more relevant buyer journey. 

Apollo offers low-cost monthly subscriptions that appeal to companies with tight budgets or companies that don’t want to commit to annual plans. 

However, Apollo’s credit-based system, with very limited access to mobile credits, may lead to unexpected costs.

Cognism’s pricing model was created to overcome the scarcity mindset and allow teams to prospect without worrying about credits. Cognism doesn’t restrict access to mobiles and emails. With Cognism, users can view as many contacts or companies as they want without incurring additional costs.

For accurate pricing, please contact your preferred data provider.

“Firstly, we trialled Apollo using a test data sample which didn’t produce adequate results. We proceeded to evaluate ZoomInfo but found the data to be too US-centric. This didn’t fit our ICP of targeting UK companies.”

“The SDRs have pulled data from Cognism for every demo booked. For every deal closed, the AEs have used the database to pull relevant contact details to influence the deal.” 

“Overall, 60% of our deals have come from the team pulling a number from Cognism.” 

And Dan Richards, Lead SDR at Hire Genius, had this to say:

“It’s not just about getting contact numbers. I’ve used Apollo and Lusha, and the numbers are ok, but Cognism beats them every time.”

“But the deciding factor for me is the data entry abilities of Cognism. I can export contacts from LinkedIn to our CRM in just a few clicks, eliminating a huge amount of data entry for me.”
