What Müller & Wulff does

Müller & Wulff GmbH, operating as MW Studio, is a custom software development studio founded in 2008 and headquartered in Greifswald, Mecklenburg-Vorpommern, Germany. The company designs and develops native iOS applications in Swift, native Android applications in Kotlin, and web applications using Ruby on Rails, alongside associated APIs and integrations. All infrastructure runs on Linux servers with nginx and MySQL, with client hosting provided on German Hetzner servers to ensure data sovereignty. Notable client projects include the SCRIBOS product authenticity verification apps (active codebase since 2017, now supporting white-label variants and SDKs), the Nachfolgeportal succession-matching platform for three German states, and the Webportal Übernachtungssteuer for Hansestadt Stralsund.

The company operates a long-term partnership business model comprising three integrated service pillars: Produktentwicklung (UX research, UI design, prototyping, design systems), Softwareentwicklung (custom native app and web development), and Hosting & Wartung (long-term hosting, maintenance, monitoring, security updates, and continued development). Pricing is scope-dependent and quote-based following an initial consultation, with revenue mechanics split between project-based professional services and recurring managed services tied to multi-year client relationships. The customer base is concentrated in German public-sector bodies and regional European SMEs and enterprises, with cultural institutions and tourism operators as a secondary segment. The company is owner-managed, with David Wulff as Managing Director and Lars Schimanski as Prokurist, and has operated without external investors since founding.

Distribution is direct and consultative, conducted via a website contact form with an explicit no-sales-pitch policy and a stated one-business-day response SLA. Marketing is content-driven through a technology-focused blog. The company does not maintain channel partners, resellers, or marketplace presence.
