What Zweitag does

Zweitag GmbH is a Münster, Germany-based digital product consultancy founded in 2008 that designs, develops, and scales custom software products for German Mittelstand and enterprise clients. The firm operates through a documented three-phase methodology (SCOPE — digital roadmap; BUILD — custom digital solution development; SCALE — team empowerment and market success) delivered by cross-functional teams combining design, development, and strategy capabilities. Its service portfolio spans web and mobile application development, IoT platform engineering, microservice ecosystems, UX and MVP prototyping, and enterprise IT integration, with named clients including BASF, Deutsche Bahn, Trusted Shops, PFREUNDT, AGRAVIS, Westfalen AG, and STRABAG Property and Facility Services.

The company's product layer is anchored by kamium, a proprietary GDPR-compliant generative AI platform that lets enterprises chat with their own corporate knowledge while keeping data inside the customer's own Microsoft account under full customer control; kamium is reported to be in use at over 50 companies and is distributed via its own dedicated website (kamium.de). A complementary asset, the KI Use Case Datenbank, offers a curated library of generative AI prompts and use cases across marketing, sales, project management, legal, HR, QM, and other functions. Zweitag holds ISO 27001 certification for information security and positions its AI offering explicitly around EU GDPR/DSGVO and EU AI Act compliance, targeting risk-averse German and European enterprise buyers.

Commercially, Zweitag runs a private, bootstrapped services-led model with no disclosed funding rounds, project-based engagements, no public pricing, and multi-year contract cadence. Demand generation is primarily content- and community-driven via an active blog, the German-language 'Digital Deep Dive' newsletter, LinkedIn, YouTube, Instagram, GitHub, and the company-hosted 'Digital Product People' meetup group, with primary engagement initiated through the website contact form. The company is led by two Managing Directors, Christian Peters and Julian Schneider.
