Why revenue leaders have switched to Cognism

01

70 percent more accurate European data

Teams switching to Cognism consistently see stronger match rates and cleaner CRM records.

This improves confidence in forecasting, routing and downstream automation without introducing compliance risk.

"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

02

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 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

03

60% more deals closed

Teams switching to Cognism report higher connection rates with verified decision-makers, supporting faster deal progression and improved sales velocity.

“The tool has paid for itself. The largest deal closed in company history was helped by generating an email from the Cognism platform. The email address allowed us to reach the contract decision-maker and close the deal earlier than anticipated.” Marc, OneUp Sales

LeadGenius mentions aligning with the California Consumer Privacy Act (CCPA) and being GDPR compliant.

Richard Caldicott
IT Director @Henderson Scott

Cognism is a globally compliant B2B data provider. Customers praise Cognism as a company that goes above and beyond to ensure customers aren’t violating privacy laws.

While being GDPR and CCPA compliant, Cognism also 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.

LeadGenius vs Cognism: Usability & Integrations

LeadGenius is built for SMEs, so the tool doesn’t have as many features and add-ons as others in the market. However, LeadGenius reviews show that users are pleased with the reliable and helpful support they get from AEs. It integrates with Salesforce, Marketo, Zapier, Outreach and HubSpot.

Cognism customers speak highly of its interface, usability and support. Integrations include Salesforce, HubSpot, MS Dynamics, Pipedrive, Salesloft, Bullhorn, Outreach and Zapier.

Then there’s the AI advantages:

  • Web app & extension: Build targeted lists in the Cognism web app, while the Sales Companion extension delivers compliant data directly from LinkedIn, corporate websites, and CRMs.

  • AI Search: Filter companies and contacts with natural language prompts, such as “Show me CMOs at FinTech companies in Germany.”

  • Sales Companion: Get a territory-ready dashboard with AI-powered recommendations, enriched by intent surges, funding alerts, hiring signals, and company events.

  • Smart Personas: Describe your business once, and Cortex builds persona-driven filters, instantly recommending the right contacts, intent topics, and technographics.

Where do Cognism and LeadGenius get their data?

According to the LeadGenius Privacy Policy, the tool collects personal information from the following sources:

  • Customers, business partners, service providers, social media networks, and advertising partners.
  • Publicly available sources - websites, public “yellow pages”, blogs, social media sites, search engine results etc. 
  • Third-party sources users connect to the platform.
  • Companies that provide personal information to supplement existing data.
  • Referral information. 

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. 

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.

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...

We like the custom datasets LeadGenius builds for us.

Custom data can be useful, but it comes at the cost of speed and scalability. Cognism’s Diamond Data® is already phone-verified and governed for compliance, so you get ready-to-use data without waiting on manual research.

Instead of building datasets from scratch, your team gets verified contacts, intent signals, and integrations out of the box. So, they can focus on selling, not sourcing.
