Pricing: $99/month vs €89-499+/month
MentionFox starts at $99/month with no annual commitment. That price includes GEO monitoring, social listening across 50+ platforms, lead generation, contact enrichment, email outreach, and active GEO optimization via Fox Promoter. The Agency tier at $499/mo adds white-label reports and multi-client management.
AthenaHQ starts at €89/month for basic GEO monitoring and scales to €499+ for advanced features, higher prompt volumes, and agency management. AthenaHQ focuses exclusively on GEO and AI visibility without bundling social listening or lead generation. The starting prices are comparable, but the feature sets included at those prices differ dramatically.
GEO Monitoring Depth
Both platforms provide solid GEO monitoring across major AI models. Both track how your brand appears in ChatGPT, Gemini, Perplexity, and Claude responses. Both show competitor comparisons and visibility score trends over time. Both track AI Overviews in search results.
AthenaHQ goes deeper in two specific areas: revenue attribution and multilingual support. Revenue attribution connects your AI visibility data to actual business outcomes, helping quantify the ROI of your GEO efforts. This is particularly valuable for teams that need to justify GEO investment to executives. The 115+ language support makes AthenaHQ one of the most globally capable GEO tools available.
Revenue Attribution: AthenaHQ's Standout Feature
This is where AthenaHQ genuinely excels. Revenue attribution tracks the path from AI visibility to website visits to conversions, giving you hard numbers on what your AI search presence is worth in dollars. For B2B companies with longer sales cycles, this data helps connect the dots between "ChatGPT recommends us" and "that recommendation generated $X in pipeline."
MentionFox does not offer revenue attribution for GEO monitoring. Its ROI tracking comes through a different channel — the lead generation pipeline. When MentionFox finds a mention, extracts a lead, enriches their contact info, and helps you close the deal, the ROI is direct and measurable. But it is not the same as attributing organic AI visibility to revenue.
The Broader Platform Advantage
MentionFox's advantage is breadth. Where AthenaHQ gives you deep GEO monitoring, MentionFox gives you GEO monitoring plus an entire social listening and lead generation platform. Social listening across 50+ platforms, lead extraction from conversation threads, contact enrichment with email/LinkedIn/phone, email outreach sequences, and active GEO optimization via Fox Promoter — all in one subscription.
For teams that need multiple tools, MentionFox can replace a GEO monitor + social listening tool + lead gen tool + outreach tool. AthenaHQ replaces only the GEO monitor, meaning you still need separate subscriptions for everything else.
When AthenaHQ Is the Better Choice
AthenaHQ is the right choice for global brands operating across many markets and languages. If you need to monitor AI visibility in Japanese, German, Portuguese, Arabic, and 110+ other languages, AthenaHQ's multilingual depth is unmatched. MentionFox's GEO monitoring has more limited language coverage.
Teams that prioritize revenue attribution over lead generation will also prefer AthenaHQ. If your goal is to prove the business value of AI visibility to stakeholders rather than directly generate leads from mentions, AthenaHQ's attribution model provides the data you need. For enterprise marketing teams with dedicated analytics functions, this is often the higher priority.
