Agencia 51

What Agencia 51 does

Agencia 51 is a full-service creative agency based in Villamayor (Salamanca), Spain, operating as a brand under parent company Grupo UNDANET S.L. The company delivers events, corporate communication, branding, advertising, digital marketing, and audiovisual production for a mix of large enterprises and SMEs, with a named client base that includes Warner Bros, Filmax, Antena 3, Telefónica, Iberia, KIA, and Universidad de Salamanca. Its service portfolio is organized around five core pillars: Eventos (physical and digital event management), Comunicación (strategic corporate communication), Branding (naming, logo, identity systems), Publicidad (cross-channel advertising), and Marketing Online (subscription-based digital marketing delivered through the Digitaliza platform), plus a Production line that leverages Grupo UNDANET's IT and software capabilities.

The underlying technology is conventional agency tooling rather than proprietary infrastructure: Google Analytics, Google Search Console, Google Ads, Facebook/Instagram Ads, Spotify Ads, and YouTube integrations support the Digitaliza subscription plans (Basic €900/month, Medium €2,100/month, Advanced €2,900/month, plus Custom). The Eventos Online sub-brand offers virtual assemblies, tastings, presentations, and congresses. Five proprietary event sub-brands (FAMILYLAND, TIRE PRO FEST, 9/16 FILM FEST, The Sustainability Gathering, Peace City World Congress) build a portfolio of owned event IP alongside client work. The firm's go-to-market is hybrid: direct enterprise sales via website contact forms and quote-based event proposals, paired with a self-serve subscription channel for SMEs on the Digitaliza platform. The headcount of 30+ professionals and a ~20-year operating history indicate a stable, organically funded mid-sized agency rather than a venture-backed scale-up.
