What k13 marketing does

K13 Marketing is a German sole proprietorship (Einzelunternehmen) founded in 2012 and headquartered in Lübbecke, North Rhine-Westphalia, owned and operated by Holger Kleffmann. The firm operates as a full-service marketing agency serving local and regional small and medium-sized enterprises (SMEs) in the Kreis Minden-Lübbecke region, with a stated focus on neuromarketing and brand psychology as the unifying methodology across its service portfolio. The team consists of approximately 15 people, including social media, SEO, and copywriting specialists.

The agency's core service offering spans six interconnected modules: Corporate Identity development, psychologically optimized website design (built on WordPress with mobile optimization, accessibility, and GDPR compliance), SEO, SEA (Google/Bing Ads), Social Media Marketing (Instagram, Facebook, LinkedIn), and Social Recruiting. Underlying these services is a methodology that integrates frameworks such as Dirk W. Eilert's Motivkompass, StoryBrand, conversion psychology, and ongoing collaboration with external experts including advertising psychologist Sebastian Fröder (since 2017), design specialist Philipp Sniechota (since 2021), and copywriter Youri Keifens (since 2022). The Neuro Web Award 2025, received for the md Hoteleinrichtungen website redesign among 1,200 submissions, externally validates the psychological web design approach.

K13 generates revenue through project-based fees and multi-year retainer arrangements under custom pricing tailored to client scope. Distribution is direct-sales led via personal 30-minute consultations and collaborative workshops, supported by content marketing (blog, podcast), social media, and SEO channels. Customer engagements span both B2B and B2C SMEs across hospitality, manufacturing, banking, brewing, agriculture, healthcare, construction, and municipal government, with several clients maintaining 10+ year relationships. The agency also operates the K13 Web-Check free diagnostic tool, custom GPT assistants trained on client brand profiles, and a podcast distributed on Spotify, Apple Podcasts, and Amazon Music.
