Market Presence & Data Strength
Europe
ZoomInfo provides European coverage, but its strength lies more in the U.S. market. While it does offer GDPR-aligned data, some users find the platform less agile when prospecting across diverse EU countries.
Apollo.io, though global in reach, often receives mixed feedback regarding data accuracy in regions like Eastern Europe and the Middle East. For European-focused prospecting, both platforms may require supplemental tools or enrichment.
United States & Global Markets
ZoomInfo leads the pack in the U.S. with unmatched data depth, enrichment, and real-time intent signals making it the preferred choice for enterprise teams.
Apollo.io dominates among startups and mid-sized businesses with over 275M+ contacts and native sales engagement features. Its freemium model drives adoption, and its global reach is strong, though international data depth varies by region.
India
ZoomInfo offers limited penetration in India, with data primarily focused on larger firms and multinational entities. Direct mobile numbers and localized intelligence are still sparse.
Apollo.io sees growing adoption in India due to its free tier and ease of access, but its database lacks reliable mobile coverage and verified local contacts.
For teams selling into India or APAC, neither platform stands out for depth, accuracy, or mobile availability highlighting a key gap in their global data coverage.
Zintlr's Data Coverage
Zintlr's Data Coverage
This is where platforms like Zintlr are bridging the divide. Zintlr offers a powerful combination of global scale and unmatched Indian market depth featuring over 90M+ Indian contacts and 400M+ global records enriched with direct mobile numbers, firmographics, and personality insights.
While Apollo.io emphasizes integrated outreach workflows and ZoomInfo leads with enterprise-grade intelligence and U.S. centric data, Zintlr strikes a balance delivering high-quality, actionable data across regions while staying intuitive and cost-effective. For teams targeting India, APAC, or managing global prospecting at scale, Zintlr emerges as a smarter, more adaptable alternative.
Apollo.io vs Zoominfo: Pricing Breakdown
Both Apollo.io and ZoomInfo follow a credit-based pricing model, a common standard among modern B2B contact and data platforms.
Apollo.io, on the other hand, offers structured monthly plans starting at $59 for Basic and going up to $149 for Organization. While it packs in features like advanced filters, dialers, and lead scoring, these are often reserved for higher-tier plans. A key drawback is that unused credits don’t roll over, and pricing scales per user potentially increasing the total cost for larger teams.
ZoomInfo, delivers high-quality, enterprise-level B2B intelligence but it comes at a premium. The base pricing starts around $15K/year for small teams, scaling up to $40K+ for enterprise needs. Credit usage, add-ons, and rigid contracts mean prices often exceed initial quotes.

Zintlr's Pricing: Flexible, Transparent, and Built for Modern Teams
If you’re looking for a platform that bridges the gap offering deep B2B data (including mobile numbers), flexible pricing, and strong market coverage across the globe and in regions like India Zintlr is emerging as a smart alternative to both. With a growing user base and a focus on data quality, affordability, and usability, Zintlr brings together the best of both worlds for modern prospecting teams.
Compliance & Data Privacy
Apollo.io, while compliant with standard data regulations, has historically focused more on scale and functionality than strict privacy positioning. It offers basic data usage disclosures and maintains GDPR-aligned practices, but lacks the depth of certification and compliance transparency. This makes Apollo a better fit for markets with less stringent data privacy environments, like the U.S.
ZoomInfo states that it complies with GDPR, CCPA, and other data privacy regulations. Its Privacy Center allows users to access, update, or delete their information, supporting global opt-out rights. Operating under the “legitimate interest” basis in the EU, ZoomInfo also offers CCPA opt-outs for California residents. While not officially GDPR-certified, the platform emphasizes responsible data handling. However, its data sourcing transparency continues to raise questions, making it essential for compliance-driven teams to evaluate its fit.
