1. Use Case: North American B2B Sales Prospecting & Contact Enrichment
A U.S.-based SaaS company needs to scale its outbound sales efforts with high-quality, enriched contact data (emails, direct dials, company firmographics). Their team also benefits from organizational charts and intent insights to prioritize outreach.
- Why ZoomInfo Excels: ZoomInfo boasts industry-leading North American B2B contact data, including highly accurate emails and direct dials. Its sales intelligence features, such as organizational charts, leadership changes, and “scoops,” provide deep context for effective outreach. Seamless integrations with CRMs and marketing automation tools make it a powerful platform for scaling sales in the region.
- Cognism, on the other hand, is weaker in North American data quality and depth compared to ZoomInfo, focusing more on European markets.
- Why Not 6sense? While 6sense helps identify in-market accounts, it often lacks the deep, direct contact details and comprehensive firmographics that ZoomInfo provides for robust prospecting.

2. Use Case: Account-Based Marketing & Predictive Lead Targeting
A B2B cybersecurity company wants to identify and engage high-intent accounts before they even reach out. Their marketing team needs to deliver personalized, data-driven campaigns and prioritize leads based on active buying signals.
- Reason 6sense is better: 6sense’s core strength lies in its AI-driven predictive analytics, which excels at surfacing in-market accounts and identifying buying signals ahead of competitors. Its robust ABM orchestration capabilities enable hyper-personalized advertising and outreach, ensuring your efforts are directed at accounts showing the highest propensity to buy.
- Why Not ZoomInfo? ZoomInfo has basic intent data but lacks the advanced AI-driven predictive analytics that are central to 6sense’s offering.
- What about Cognism? Cognism is more geared towards direct prospecting and lead generation rather than comprehensive predictive ABM.

Cognism is a B2B sales intelligence and lead generation platform that specializes in global contact data, particularly mobile numbers, and compliance-focused outreach.

3. Use Case: Global Outbound Sales with a Focus on Mobile Numbers
A European-based SaaS company is expanding into EMEA and APAC markets. Their outbound sales team needs verified mobile numbers to directly call decision-makers and accelerate prospecting while ensuring compliance.
- Why Cognism is the best: Cognism offers superior mobile number coverage, particularly in Europe and APAC, which is critical for direct outreach in these regions. Its strong emphasis on GDPR and CCPA compliance provides peace of mind for legal cold calling. The intuitive Chrome extension further streamlines prospecting directly from platforms like LinkedIn.
- How about ZoomInfo? While powerful in North America, ZoomInfo’s mobile number coverage is weaker in EMEA/APAC.
