Congnism is great for anyone in sales , mainly due to integration with other platforms, finding contacts with correct email and phone numbers. They need some improvements with multiple platform integration.

The expectation is to give them your personal email address to get a personal phone number removed from their database, that they did not have permission to have in the first place !

An excellent tool for outbound initiatives

This platform has proven to be a highly dependable resource for our outbound strategies. The quality of the data is impressive, particularly for contacts in the EMEA region, and it is user-friendly. GDPR compliance is a significant benefit for teams in Europe, and the support team has been attentive whenever assistance was required. All in all, a robust solution for B2B prospecting.

Steer clear of this service

This service seems to provide inaccurate contact data. My phone number was wrongly linked to someone I don't know, resulting in numerous unsolicited calls. Based on this experience, I have serious doubts about their data quality and how they handle complaints. I recommend avoiding them!

Solid B2B data quality with potential for enhancement

This sales intelligence platform is well-organized and effectively aids in daily B2B prospecting. The data and insights on decision-makers are mostly dependable, facilitating quicker research and outreach preparation. The browser extension is user-friendly and integrates smoothly into typical sales processes. However, there are some minor issues. Occasionally, contact information is outdated, and the extension's performance could be improved. Additionally, offering more detailed control over data exports and filtering would enhance usability for experienced users. Overall, this tool is beneficial for sales and business development teams, and a few enhancements in data accuracy and performance could easily merit a full 5-star rating.

Lack of response to data inquiries

This service has created false data about me by associating my email with someone else in finance, resulting in a flood of unrelated finance emails. Despite submitting two requests for data access, I have received no reply. Their forms require business and LinkedIn details, which I do not possess, making it impossible for me to submit my inquiries.

Concerns about data selling

I recently discovered that my data has been sold, leading to daily calls. Additionally, the online form to request data removal is not functioning.
