What Link Affinity does
Link Affinity is a Spanish-incorporated SaaS company (legal entity FuSEOn Pro Tool S.L., founded by Sico de Andrés) that develops Affinity PRo, an AI-powered digital PR and link building platform marketed under both the Affinity PRo and Link Affinity brands. The platform combines NLP-based semantic affinity analysis, a proprietary Naturalness Algorithm that detects artificial link patterns, generative AI for topic and opportunity discovery, brand perception analysis across Google, ChatGPT, and media outlets, an integrated CRM for media outreach, and an Expert Network (branded Expertomy) for content collaboration.
The business operates a freemium SaaS subscription model with a free account tier and paid plans accessible at affinitypro.io, supplemented by an enterprise demo motion via Calendly and a Certified Partner agency program (with a Partner Excellence tier). Named channel partners include Havas Media Group, Internet República, Flat 101, Webpositer, Human Level, and Miogroup. The product serves SEO agencies, digital marketing agencies, and freelance SEO consultants managing link building and brand authority campaigns across global markets, with English and Spanish localization launched in 2025.
The company appears to be bootstrapped and founder-led: no funding rounds, parent entities, or institutional investors are disclosed. It has won two Global Search Awards (Best Software Innovation in 2021 and Digital PR Tool Software of the Year in 2023), providing third-party validation of its technology positioning in the digital PR category.
