Why revenue leaders have switched to Cognism

01

85% data accuracy

Cognism delivers phone-verified Diamond Data®, improving the accuracy of mobile contact data and reducing wasted outreach across global revenue teams.

Customers report higher first-connect rates and fewer unproductive dials, enabling more efficient execution at scale.

 

“We previously used ZoomInfo and saw contact information accuracy rates of around 50%.” “When we tested Cognism’s data as part of the procurement process, we recorded data accuracy of around 85%.” Justin, Bright Network

02

30–40 percent reduction in tech overhead costs

Credit-based pricing models restrict outreach and create hidden cost pressure as teams scale activity across markets.

Cognism removes credit ceilings, giving revenue leaders predictable access to European data without throttling execution or forcing incremental spend.

“Price is irrelevant; it’s all about ROI, and Cognism won the battle. The decision to move from Lusha was a very easy one.” Louis, Team Sunday

03

Over 75% match rate

Cognism Enrich delivers consistently high match rates, helping teams maintain clean, complete CRM records at scale.

“As for the percentage enrichment rate metric, we took a different sample set of 500 contacts that didn’t have an email address or phone number. Again, Cognism came out on top with over 75% match rate, higher than all other vendors.” Siddhartha, Darwinbox

What’s the difference between Seamless.AI and Cognism?

When comparing Cognism to Seamless.AI, consider the quality of the sales data and the features for the price.

For instance, Seamless doesn’t offer phone-verified mobiles, and its data is geared toward the US, claiming that the tool is unsuitable for use outside of the US.

Cognism is a leader in US mobile coverage. It also has the most complete data in EMEA with phone-verified mobiles for outstanding prospecting results.

Here’s a quick summary of how the two tools compare:

Why teams switch from Seamless.AI to Cognism

“We reviewed Cognism and tools like Lusha, Seamless.AI and ZoomInfo.” “I think from the outside, these tools look very advanced and fancy. They claim to be a 5-in-1 solution, or they can do anything we want to do.” “But we had a trial for one and discovered that the database was not very up to date. Compared to Cognism, it’s very old. The European database is not as strong as Cognism.” “In terms of pricing, they were very expensive, and everything is an ‘add-on’, so the packages alone are very limited. For example, you’d have to spend double the amount to get something as simple as a new filter.”

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 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.”

IT Director @Henderson Scott

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 Italy, 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 that are on DNC lists from reps. Meaning that its customers have complete confidence in the legality of its outreach.

The Cognism platform follows these compliance-based actions: 

  • A stringent B2B data verification process. 
  • Ensures all data is legally sourced and of the utmost quality.
  • Is regulated by the ICO and provides users with a notified database.

Seamless.AI vs Cognism: Usability & Integrations

Seamless.AI offers a tool that syncs easily with CRMs. Integrations include Salesloft, HubSpot, MS Dynamics, Salesforce, Pipedrive and Zoho.

Cognism includes integration with Salesforce, Hubspot, MS Dynamics, Pipedrive, Salesloft, Bullhorn, Outreach & Zapier in all packages.

The Cognism web app makes it simple for teams to build targeted lists, while the Sales Companion browser extension lets reps prospect seamlessly across LinkedIn, corporate websites, and CRMs. Instead of hunting through multiple tools, salespeople get compliant, high-quality data wherever they work online.

Cognism’s AI Search allows users to filter companies and contacts with natural language prompts. Just type (or speak) what you’re looking for, and AI Search returns a tailored list of accounts and contacts using automated filtering logic. For example: “Show me CMOs at FinTech companies in Germany.”

Sales Companion is built to optimise seller time — shortening the path from research to revenue. With AI-powered contact and company recommendations, reps get a personalised dashboard pre-filtered to their territory, surfacing in-market decision-makers automatically. Cortex enriches this further with intent surges, funding alerts, hiring signals, and company events, helping reps multi-thread and generate pipeline faster.

With Smart Personas, users can set up persona-driven contact recommendations in seconds by simply describing their business and what they sell. Cortex translates that into job title, country, industry, and segment filters, and can also recommend relevant intent topics and technographics based on the business model.

Sounds great, but...

Seamless.AI has an AI Assistant. 

Seamless.AI’s writing assistant can generate outreach copy, but sales teams don’t win on more content; they win on better context.

Cognism’s Cortex AI is governed, compliant, and powered by verified data. It delivers AI Search, Smart Personas, and real-time contact recommendations.

Unlike Seamless, our AI assistant is included in every package and not sold as an add-on, so every team gets the context they need to drive real conversations that convert.

Cognism vs Seamless.AI: Databases & Data Coverage

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.AI 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. 

Machine learning processes check millions of data points daily, and a team of researchers verifies the data. This ensures accuracy and compliance, and the 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 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. 

Here’s how Cognism mobile phone numbers differ from standard mobile numbers. 👇

How standard mobile numbers compare to Cognism's phone-verified numbers.

Sounds great, but...

Seamless.AI has stronger US coverage.

While Cognism is known for its excellent EMEA data coverage, it’s not lacking in the US. Customers have reported 90% accuracy in US markets, with praise for contacts in niche markets.

Seamless.AI Pricing

According to its website, Seamless.AI pricing includes two paid packages and a free plan. Every package includes:

FAQs about Seamless.AI vs Cognism

Cognism is a sales intelligence platform that is one of the best Seamless.AI alternatives. Cognism is a leader in US mobile coverage and has the most complete data in EMEA with phone-verified mobiles for outstanding prospecting results.

Cognism is the better choice for businesses looking for a sales intelligence platform that offers up-to-date, accurate data in an easy-to-use interface. The quality of its verified mobiles and B2B emails are unmatched by Seamless, as are its user-friendly interface and excellent customer service. 

So if you’re looking for the best tool to help you reach out to potential leads and target customers, Cognism is the clear winner.

Yes, Cognism is an excellent alternative when comparing Seamless competitors. Cognism provides highly accurate and up-to-date contact information that helps sales and marketing teams find the information they need to make fewer calls, contact the most relevant people, and hit quota faster. 

Furthermore, Cognism has received overwhelmingly positive reviews from its users. In particular, many users praise its user-friendly interface, accurate data and excellent customer service.

Seamless.AI follows the California Consumer Privacy Act (CCPA) and states in its Terms of Use that the services offered might not be suitable for use outside the US.

There’s no mention of GDPR compliance or DNC list scrubbing. What’s more, Seamless.AI resells user data that includes personal emails, which require different levels of consent and compliance obligations. 

Cognism does not extract user-submitted data through its browser extension to sell. It only includes B2B emails to ensure GDPR and CCPA compliance. Even better, Cognism offers DNC list filtering for 13 countries.

Seamless.AI offers three pricing plans and a free trial. You'll need to request a demo in order to receive a quote which might be less than a Cognism quote. 

Keep in mind that Seamless.AI uses a credit-based pricing system. So your team will need to purchase more credits when they run out.

Cognism data is unrestricted, which offers more value to teams, especially heavy diallers.

All Cognism plans include features and integrations designed to make prospecting as efficient as possible. There are no hidden platform fees; you only pay for licenses and add-ons.

Seamless.AI uses a co-op model for intent data, pulling signals from a network of B2B publishers and online activity.

While this provides some visibility into buyer research, it isn’t tightly connected to verified contact data and is sold as an add-on, which may make it less flexible and more costly to use.

Cognism, on the other hand, partners with Bombora, the industry leader in intent data, to provide up to 100 premium intent topics, which are included and configurable during onboarding.

Crucially, these insights are combined with Cognism’s Diamond Data® phone-verified mobiles and verified emails, so GTM teams can act immediately on trusted, in-market buying signals.
