Seidemann Web

What Seidemann Web does

Seidemann Web GmbH is a German e-commerce development agency headquartered in Reutlingen, founded in 2014 as a spin-off from seidemann: solutions GmbH. The firm delivers custom online shop development, ERP integration, and related e-commerce services for mid-market and enterprise retailers in Germany and Austria, with a portfolio of named clients spanning equestrian, sports, footwear, design furniture, automotive, and warehouse logistics verticals (e.g., Paul Schockemöhle, Bergspezl, Vamos, Groundies, Champion Öl, Pirschershop, Groeger Bauaufzüge, designkatalog, MH Direkt).

The core technical offering is built on Shopware 6 and OXID eSales Enterprise Edition, complemented by a proprietary middleware called sol:fusion — developed by the sister company seidemann: solutions — that connects SoftENGINE ERP Suite with Shopware, OXID eShop, and seller portals such as Tradebyte and Brickfox. The agency supports headless storefront implementations, professional development environments with versioning, automated deployment, and multi-stage testing, and packages cyber security and SEO/performance services around the core build. The firm operates as a certified partner of Shopware AG and OXID eSales AG and maintains a broad partner ecosystem spanning payment, PIM, search, hosting, and email marketing vendors.

Commercially, Seidemann Web operates as a sales-led professional services firm with project-based engagements and ongoing maintenance contracts. No public pricing is disclosed. The agency does not appear to use resellers or indirect channels; clients are acquired through direct outreach, partner referrals, and a portfolio-based website presence. The company is privately held, has no external funding, and combines with its sister company to approximately 60 employees. Managing Director Oliver Richter leads the standalone GmbH (Handelsregister Stuttgart, HRB 749221).
