TL Digital Solutions GmbH is a remote-first company that provides a collaborative logistics platform called TradeLink. We simplify B2B shipment collaboration for mid-sized businesses. Our open layer connects users, assets, and systems in shared shipment processes, offering simple workflow tools to all participants.
