12 Best Apollo.io Alternatives & Competitors (2026)

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.

Clearbit focuses on real-time company and contact enrichment APIs that integrate directly into marketing and sales workflows. Its strength lies in lightweight, developer-friendly data pulls for personalization at scale. Versus LeadGenius, Clearbit offers narrower global coverage and minimal human verification, making it less suited for teams requiring fresh, opted-in contacts or monitoring of role changes across EMEA and emerging markets. It serves best as a supplementary tool rather than a full replacement for comprehensive B2B intelligence.

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.
