What aditive does

aditive is a privately held German full-service media agency (Medienagentur) operating as a civil-law partnership (GbR) — Stefan Pörtner & Peter Tröger GbR — founded in 2006 in Munich and now headquartered in Würzburg with a secondary presence in Munich. The company is bootstrapped, with no external investors, no funding history, and no subsidiaries. Self-described as a "small media agency" (kleine Medienagentur) with 11-50 employees, aditive offers two business lines from a single brand: (1) a project-based media agency arm providing classical advertising, web development (WordPress, ProcessWire, WooCommerce implementation), corporate design, 3D visualization and animation, photography, image-film production, and consulting; and (2) the aditive onlineShop, a WooCommerce-powered e-commerce storefront selling standardized physical products — Alu-Dibond signs and B1-certified vinyl stickers for recycling reminders and safety notices — Made in Germany and shipped within 24 hours.

The underlying technology stack is conventional: WordPress and WooCommerce for e-commerce, ProcessWire and HTML for agency web builds, and 3D visualization/animation tooling for creative services. There is no proprietary platform, no API surface, no mobile app, and no AI/ML layer. Distribution runs through the proprietary aditive.de/shop storefront, the Amazon.de marketplace for select SKUs, and direct consultative sales for agency engagements; checkout supports PayPal plus a broad set of European bank-based methods (Bancontact, BLIK, EPS, iDEAL, MyBank, Przelewy24, Trustly, Multibanco). Unit prices for physical products are low (€6.00-€21.90) with volume discounts up to 15% and free domestic shipping.

Customer reach spans 100+ named organizations across large enterprises (Bayer, Microsoft, Infineon, LEGO, McDonald's, Nokia, Danone, Goodyear, Serviceplan), education (Universität Würzburg, LMU, TUM, Universität Augsburg, Universität Zürich), healthcare (Klinikum Coburg, Rhön-Klinikum), and government/insurance (Versicherungskammer Bayern), supplemented by long-tail B2C online shop buyers. aditive holds a registered trademark (aditive®), is actively operating (2026 copyright), and concentrates its footprint in Germany with cross-border EU payment readiness but no disclosed international offices.
