1. Cognism
Cognism is one of the top Seamless.AI competitors on the market. It’s an AI sales intelligence solution that drives customer revenue growth in Europe. Use it to create strong pipelines with high-quality and compliant B2B data that connects teams with senior-level contacts faster than ever before.
Cognism also includes an AI-driven solution called Sales Companion. It’s designed to give sales teams personalised access to in-depth account data and ensure fresh outreach with the next best profile suggestions.
Fuelled by Cognism's high-quality contact data, including five forms of firmographic signals, it drives healthy pipelines in target markets.
How does Cognism stand out against Seamless.AI?
If you’re focused on expanding into Europe or want to win more deals there, then you need Cognism.
The major difference between Cognism and Seamless.AI is that Seamless states its services are not appropriate for use outside of the US.
Unlike Seamless.AI, Cognism was built for the European market and prides itself on being GDPR and CCPA-compliant.
Its data is checked against DNC lists in 13 countries, more than most other data providers, including Seamless, which doesn’t mention DNC list filtering on its site.
What’s more, Seamless.AI collects user-submitted data through its Chrome Extension to resell. This includes personal emails. While having personal email addresses can be exciting, it can require different levels of consent and compliance obligations.
Cognism does not extract user data from its browser extension and only supplies B2B emails to ensure compliance.
Key features

- Phone-verified cell phone numbers to help you connect with 87% of your list.

Tips for choosing a quality Seamless.AI competitor
When looking at Seamless.AI alternatives, consider if your favourite tool has all the features that are important to your business.
It’s also a good idea to compare pricing.
Some sales tools cost more than others but offer better data coverage and features, while some are more affordable but might lack the products your business requires for success.
For example:
Intent data helps teams discover customers who are searching for a service or product like theirs and are ready to enter the sales funnel.
This might not be an essential part of your prospecting workflow. Instead, you might want a prospecting tool with accurate mobile numbers or GDPR-compliant contact data. Not all Seamless.AI alternatives supply these features.
You might also discover that some Seamless.AI competitors, like Cognism, have unrestricted access to data on all plans, while other tools have credit limits on all but their most expensive custom plans.
Top tip:
Check out customer reviews and case studies to better understand how each platform works and how it compares to Seamless.
