Advertising Services Madrid, Community of Madrid 201–500 employees Founded 2002 Privately Held

SIDN is a Madrid-based digital marketing consultancy founded in 2002, now scaling programmatic and first-party audience capabilities across Spain and into Europe and the US. The tech stack reveals a performance-marketing operation (Google Ads, Meta, DV360, The Trade Desk, BigQuery) paired with measurement (GA4, Looker Studio, server-side tracking) and content distribution (YouTube, TikTok, LinkedIn). The hiring surge is almost entirely marketing-focused (12 of 14 open roles) at senior levels, signaling aggressive demand-gen or client-retention scaling rather than product engineering.
