SocialBook is a two-sided marketplace connecting brands with influencers: search and filter more than 300 million creators, use AI Product Diagnosis to analyze competitor data and get influencer recommendations, manage brand-influencer collaboration, track analytics across Instagram, YouTube and TikTok, check for fake followers, calculate fair influencer rates, and optionally use fully managed campaign services for sourcing, outreach and negotiation.
AI Product Diagnosis specifically – analyzing competitor marketing data to recommend which influencers actually fit a brand, rather than just search filters by follower count or niche – targets the harder matching problem brands actually struggle with. A built-in fake-follower checker is also a genuinely useful trust feature in an industry where follower-count fraud is a well-documented, common problem.
Free to join for both sides is a low barrier to entry, but the platform’s real value concentrates in the paid managed-campaign services and credit-gated AI Diagnosis feature – a brand evaluating fit should budget for those rather than assuming the free tier covers a complete campaign end to end.
