What Underline does

Underline a.s. is a privately held, full-service strategic, creative, and communication agency headquartered in Galerie Mánes, central Prague, Czech Republic, with a secondary registered office in Prague 2. Founded approximately two decades ago and led by Director Marek Řídký, the firm operates with a headcount of 11–50 employees and serves major Czech and international enterprise clients across telecommunications (T-Mobile), consumer electronics (Panasonic), energy (E-ON, ČEPS), retail (Albert/Ahold, OBI, Penny Market), finance (ING, GE Money, Raiffeisen Bank), beverages (Budějovický budvar, Becherovka), consumer goods (Wrigley, Colgate-Palmolive), real estate (CBRE, Galerie Myslbek), and entertainment (Ticketmaster).

The agency's service portfolio is built around an integrated 360° communications model combining digital, social, direct, new media, events, guerrilla & viral, loyalty & motivation, TV, print, outdoor, radio, and PR. Specialized lines include influencer marketing (with a 5,000+ influencer database and up to 20-metric brand analysis), user testing and reviews for e-commerce clients, and custom website/campaign-microsite development. Underline has no proprietary technology platform; its execution stack relies on standard third-party tools — Google Analytics, Facebook/Meta, LinkedIn, and the Czech-market Seznam.cz — for analytics, social media management, paid advertising, and influencer activation including dark-post campaigns.

Commercially, Underline operates as a B22B professional services firm using a direct enterprise sales model. Revenue derives from project-based fees and ongoing client retainers, custom-quoted by scope; pricing is not publicly disclosed. The company is privately owned by founder/management (no institutional investors disclosed), has no funding history, and operates solely within the Czech Republic market under the legal entity Underline a.s., a Czech joint-stock company (akciová společnost).
