What Kosmonaut does

Kosmonaut (legal entity: KOSMONAUT Germany GmbH) is a private, owner-managed E-Commerce agency founded in 2016 in Rheda-Wiedenbrück, Germany. The firm operates at the intersection of design, data, and technology, delivering end-to-end E-Commerce transformation services including consulting, platform implementation, system audits, CX/usability design, composable commerce architecture, integrations, cloud hosting, and ongoing optimization. It serves mid-market and enterprise clients primarily in the DACH region and internationally, targeting B2B industrial manufacturers, D2C brand manufacturers, and omnichannel retailers.

The agency's core technology stack spans leading E-Commerce platforms — commercetools (API-first, headless, MACH principles; certified partner with 11 certificates since 2020), Shopify Plus, OXID eSales, and Shopware — supported by a proprietary React/Next.js headless frontend called Darkstar, a Blueprint methodology for multi-brand rollout, and a reusable Pattern Library. It integrates complementary best-of-breed tools including Findologic, Makaira, ROQQIO, ScaleCommerce, Klarna, and Unzer. The team of approximately 35 internal and external specialists is distributed across Germany, Vietnam, Lithuania, Poland, Spain, and Bulgaria.

Kosmonaut's business model is predominantly project-based professional services, with milestone-tied payments (30% upfront, remainder on progress) for consulting and implementation work, plus an annual recurring maintenance and support stream. No public pricing is disclosed. GTM is sales-led and consultative, anchored on enterprise logos including Schüco International KG, SW-Motech, Rotkäppchen-Mumm Group, Lucky Bike, HARK, Ludwig von Kapff, Bad Heilbrunner, and Steinel. The agency is self-financed, independent, and bootstrapped, with four Shop Usability Awards (including Agency of the Year 2020) as its principal brand credential.

Core offering

Kosmonaut is an international E-Commerce agency that designs, builds, and optimizes E-Commerce platforms for enterprise and mid-market brands. It delivers E-Commerce consulting and strategy, design and development services, and platform implementation across commercetools, Shopify Plus, OXID eSales, and Shopware.

Product overview

Kosmonaut is an international E-Commerce agency operating at the intersection of design, data, and technology. Rather than offering a single unified SaaS product, it provides a portfolio of strategic, creative, and technical services organized around four pillars: Engagement (customer data platforms, marketing automation, personalization), Experience (CX audits, usability, design systems, A/B testing), Engineering (system audits, composable commerce, development/integration, cloud architecture, PIM/DAM/MDM), and Enablement (technical operations, content management). The agency implements these using best-of-breed e-commerce platforms — primarily commercetools (for composable/API-first B2B, B2C, and D2C), Shopify Plus (for rapid time-to-market), OXID eSales (for scalable B2B/B2C), and Shopware — supported by a proprietary React/Next.js frontend called Darkstar. Complementary tools integrated per project include Findologic (search/navigation), Makaira (headless storefront), ROQQIO (middleware/commerce cloud), and ScaleCommerce (cloud hosting).
