# Arcalea > Arcalea is a marketing intelligence firm that connects marketing spend to closed revenue. It builds four proprietary systems, Galileo (multi-touch attribution), Compass (search intelligence), the AEO Index (AI search visibility), and QMA (Quantitative Market Assessment), on a single first-party data architecture, and delivers SEO/AEO, paid media, and data/AI services on top of them. Arcalea's core philosophy, consistent since 2015: marketing is a measurable science. The company is known for rigorous, first-party attribution and for early, in-depth work on Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO), how brands earn citations in AI answer engines such as ChatGPT, Perplexity, Gemini, and Google AI Overviews. ## Platform & products - [The Arcalea Intelligence Platform](https://arcalea.com/platform): Overview of the four proprietary systems and the shared data architecture behind them. - [Galileo, Attribution Intelligence](https://arcalea.com/galileo): Multi-touch attribution built on first-party CRM/ERP data, with five attribution models, independent of platform self-reporting. - [Compass, Search Intelligence](https://arcalea.com/compass): ML analysis of total addressable search demand across traditional and AI search, quantifying the economic value of organic visibility. - [AEO Index](https://arcalea.com/aeo-index): Recurring research measuring brand visibility and citation share inside AI answer engines. - [QMA, Quantitative Market Assessment](https://arcalea.com/qma): Competitive-landscape and market-entry analysis across 20 dimensions before budget is committed. - [Integrations](https://arcalea.com/integrations): Native CRM/first-party data integrations (HubSpot, Salesforce, SugarCRM, Slate, Epicor, Tealium, and more). ## Services - [SEO & Answer Engine Optimization](https://arcalea.com/seo-aeo-content): Traditional search, AI answer engines, and content built to be cited and to move buyers. - [Paid Media Management](https://arcalea.com/paid-media): Paid search, paid social, programmatic, and native advertising managed against revenue outcomes. - [Data, AI & ML](https://arcalea.com/data-ai): Multi-touch attribution, audience intelligence, CRM integration, agentic AI workflows, and ML data pipelines. - [How it works](https://arcalea.com/how-it-works): Arcalea's engagement model and how the four systems are deployed. ## Guides & research - [Marketing Planning Diagnostic](https://arcalea.com/diagnostic): A free, 21-step self-guided marketing planning diagnostic built on G-STIC, the 5Cs, Kellogg 7Ts, and Arcalea’s QMA.
