Cognism is the best data governance vendor for quality, up-to-date, and European B2B data. It’s well-suited to organisations that require a compliant data foundation, including alignment with GDPR and CCPA, and depend on reliable contact data to engage decision-makers effectively.

Verified mobile data increases the likelihood of reaching the right contacts, supporting more consistent execution across target accounts.

Cognism offers flexible access and exporting options designed to support how revenue teams actually work, without creating unnecessary friction in day-to-day execution.

2. Lead411

Best for businesses on a budget with a focus on US prospecting across channels.

Lead411 is a USA data vendor that provides company, employee, and buyer intent data as well as features for sales and marketing. It helps sales reps get general prospect information and research in-market prospects actively looking for a solution online.

When considering this B2B data provider, keep in mind that you’ll need credits to unlock contact data. Users also mention limited EU, APAC, and LATAM data. 

Top features:

• Buyer intent data
• CRM Enhancer

• Multi-channel campaigns

Pricing: 

Lead411 offers monthly and annual plans. Depending on the duration, you can choose between Basic, Pro, and Unlimited. Up-to-date pricing is available on its website.

3. Seamless.AI

Best for automated lead generation in the US.

Seamless.AI is a data-as-a-service vendor that uses AI to crawl the web and discover lead generation data.

When it comes to datasets, Seamless is predominantly US-focused. The Seamless.AI Terms of Use state that it cannot represent that the services are appropriate for locations outside the United States.

What’s more, this database provider collects customer-submitted data to improve its database.

Top features:

• Buyer intent data
• CRM Enhancer
• Lead scoring
• Multi-channel campaigns

Pricing: 

Seamless.AI pricing packages include Free, Pro, and Enterprise. The pricing is based on credits and the required number of user seats.

“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.”

Adapt.io is a B2B database vendor that allows you to find the most important information about your prospects and personalise your B2B outreach campaigns.

Best for small to mid-sized sales teams and professionals focusing on tailored communication and improved outreach.

LeadIQ is a B2B data provider that collects information from public and private sources (social media platforms, job boards, SERPs). It integrates with all major CRM platforms like Salesforce, but may not be suitable for heavy dialers, as every LeadIQ plan limits the number of mobile numbers.

While its integrations are good, it requires its users to ensure GDPR compliance with any data they control.

Top features:

LinkedIn Sales Navigator is one of the top data companies for prospecting. You can use it to build prospect lists on LinkedIn, and it has one of the largest professional databases for recruiters and SDRs.

While users can only access some features on Advanced and Advanced Plus plans, they can narrow their search based on industry, location, company size, job title, etc.

However, while you can research and send InMails to prospects and companies in your target market, Sale Nav is not a data provider.

Apollo.io is one of the big data vendors with automation capabilities for scaling outreach. It helps teams uncover leads quickly and efficiently. 

Apollo uses a dual credit system that charges users once per mobile and once per email, which may make it costly for dial-heavy users. Plus, according to Apollo’s T&Cs, the company can use customer-submitted data to supplement its database.

Furthermore, if compliance is key for you, be aware that Apollo.io had two data breaches in 2018 and 2021.

Top features:

• Buying intent and intent filters
• Data enrichment
• Sales call transcriber, analyser, and insight extractor

15. ZoomInfo

Best for Enterprise businesses looking for a comprehensive solution in the US. 

ZoomInfo is one of many data providers in the USA. Its algorithms gather data from millions of sources in real-time. You can access a suite of business intelligence tools that include detailed company profile insights, including revenue, technology usage, number of employees, and more.  

Like many email providers on our list, ZoomInfo pricing is credit-based. While ZoomInfo has expanded its database into Europe, its global data and certain features come at an extra cost. 

What’s more,  although it’s a trusted data vendor, some users complain about the freshness of the data it collects.

Top features:

• Sales automation.
• Web form optimisation. 
• Digital advertising. 
• Buyer intent. 
• Website visitor tracking. 

Pricing: 

You must request a custom ZoomInfo pricing quote. You can choose different tiers for sales, marketing, and recruitment.

When evaluating data service providers, data accuracy is everything! Cognism is the best choice for high-quality B2B data. 

Just ask Mollie: 

“Cognism’s data quality was about 30% better than everything else we were looking at.” “With ZoomInfo, the data quality in Europe isn’t what we would need. With Lusha, we get something, but when we dial, it’s not at all where we would expect it to be.”
