Lang Consulting Backs E-Commerce Pitch With Revenue Guarantee

Freiburg – October 29, 2026 -- Lang Consulting GmbH says it has supported more than 1,200 online shops over more than seven years. The Freiburg-based agency is pitching verifiable credentials as the main filter for retailers choosing an e-commerce partner.
Founder and Managing Director Sven Lang argues that a wrong choice costs a shop operator more than the service budget. In the worst case, the retailer loses months in which the business should have been developing. In his view, polished websites and high revenue claims do not show who actually delivers the work, how experienced those people are, or which obligations the provider accepts. Lang built and ran online shops before founding the company.
