Adsum Agency

Adsum (formerly Seogi) is a Dutch performance marketing agency based in Den Bosch, specialising in e-commerce growth for established brands. The site was built around a complete rebrand, requiring a clean, professional aesthetic that balances authority with approachability. The design uses strong editorial photography, a warm neutral palette, and a service structure built around five clearly differentiated specialisms. The build includes a CMS-driven cases and news section, a sticky contextual navigation with dropdown specialisms, and an inline callback widget. The site is positioned to attract senior e-commerce advertisers, and the copy and layout reflect that audience throughout.
