12 Best Clearbit Alternatives & Competitors (2026)

ZoomInfo is a comprehensive B2B intelligence platform offering a large static database of contacts, company data, and intent signals primarily focused on North American markets. Its strengths include broad search filters, buying signals, and CRM integrations that appeal to large sales teams. Compared to LeadGenius, ZoomInfo provides less emphasis on live on-demand human-verified data for LATAM or APAC regions and offers fewer niche vertical contacts outside tech and finance. Pricing tends to be higher for full access, making it less flexible for teams needing tailored global coverage or behavioral insights beyond standard technographics.

Crunchbase delivers company profiles, funding data, and investor information with a focus on startups and public markets. It excels at tracking venture activity and executive changes but updates less frequently than MixRank's hourly cadence. Pricing is tiered with a free tier available, making it more accessible for light research, while MixRank targets high-volume data teams needing raw feeds and technographics. Use Crunchbase when you need broad funding signals rather than deep mobile SDK or web tech install data.

Apollo.io combines a contact database with sales engagement and sequencing tools in one platform, popular among SMB and mid-market teams for its affordable plans and ease of use. It offers strong email finding and basic enrichment features. In comparison to LeadGenius, Apollo relies more on scraped and user-contributed data rather than AI plus human-in-the-loop verification, resulting in lower accuracy for international or niche segments. It lacks LeadGenius's specialized contact activation and deep buying committee mapping for complex enterprise deals.

data.ai (formerly App Annie) specializes in mobile app market data, downloads, and revenue estimates. It provides deeper app store analytics than MixRank but minimal company or people data. Choose data.ai for pure mobile performance tracking and MixRank when you also need technographics, employee profiles, and hourly B2B enrichment.

BuiltWith focuses on website technology profiling and lead lists derived from web tech installs. It provides good historical data but lacks MixRank's people dataset depth and mobile app coverage. Many users pair BuiltWith with other tools for full enrichment, whereas MixRank serves as a more unified source for both web and mobile intelligence.

LinkedIn Sales Navigator provides advanced search and lead recommendations based on professional network activity and company updates. It excels at social selling and relationship mapping. Compared to LeadGenius, it lacks deep technographic or behavioral intel beyond public profiles and offers limited support for bulk data delivery or privacy-compliant activation in regions outside major markets. Many teams use it alongside LeadGenius alternatives for social signals but need additional providers for global contact accuracy and buying group completeness.

SimilarWeb offers website traffic analytics and competitive intelligence with strong digital market insights. It complements rather than replaces MixRank by adding audience metrics that MixRank does not emphasize. Pricing is subscription-based and geared toward marketers, while MixRank targets data teams needing raw company, people, and SDK datasets.

Lusha delivers affordable contact data and enrichment focused on emails and phone numbers with browser extensions for quick lookups. It targets sales development teams needing fast access. In contrast to LeadGenius, Lusha has weaker global coverage beyond North America and Europe and does not provide the same level of AI-human hybrid insights or contact monitoring for role changes. It works well for basic prospecting but falls short for RevOps teams managing complex international ABM programs.

Seamless.AI uses AI to find and verify business contacts in real time through its browser-based search tool. Its strength is speed for US-centric lead generation. Relative to LeadGenius, it provides less emphasis on human-verified niche segments, LATAM/APAC coverage, or advanced features like behavioral intel and buying committee visibility. Pricing is usage-based but data freshness can vary, making it a lighter alternative for teams not requiring enterprise compliance or global scale.

RocketReach offers a searchable database of emails, phones, and social profiles aimed at recruiters and sales professionals. It is known for competitive pricing and broad US coverage. When compared to LeadGenius, RocketReach lacks real-time monitoring, human-in-the-loop depth, and strong international reach in emerging markets. It serves simple lookup needs effectively but does not match LeadGenius for tailored data delivery or privacy-focused activation of in-market buyers.
