Cognism vs Seamless.AI: Databases

Seamless data may only be suited for the US; its Terms of Use state that it cannot represent that the services (including data) are appropriate for locations outside the United States.

Cognism has research teams in the EU and the US, making it an excellent option for anyone looking to find highly-targeted leads across NAM, APAC and EMEA.

Quality is of utmost importance to Cognism, with phone-verified numbers and the most complete data in Europe. What’s more, Cognism has 2x more cell number coverage in the United States.

Where do Cognism and Seamless get their data?

Seamless.AI collects personal information from any accounts its customers choose to link. These include websites, professional networks, CRMs, social media platforms, email and mobile contacts.

It also collects personal data from the Seamless.AI Chrome extension, the website, and with your consent. 

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. Unlike Seamless,  it does not supplement its database with user data. 

Data accuracy and currency are ensured via machine learning processes that check millions of data points daily. A team of researchers verify 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 3x more likely 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. A feature that Seamless.AI does not include. 

Diamond Data® allows sales teams to connect with up to 87% of their prospecting lists.

Seamless.AI versus Cognism: Compliance

Seamless.AI follows the California Consumer Privacy Act (CCPA).

There is no mention of it being GDPR compliant on the website or whether or not the tool scrubs numbers against DNC lists. 

What’s more, some Seamless.AI reviews on G2 mention the use of personal emails. While having personal email addresses can be exciting, they can require different levels of consent and compliance obligations. 

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, Australia, Canada, New Zealand, Belgium, Croatia, France, Germany, Ireland, Portugal, Spain, and Sweden.

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.”

Cognism compliance - GDRP & CCPA

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.”

Seamless.AI vs Cognism: Usability

Seamless.AI offers a tool that syncs easily with CRMs.

Cognism customers speak highly of the tool’s interface and usability:

“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”
