We developed Welcomy, a B2B web-app management-solution where the sales-, marketing-, and account staff can intelligently manage the "last mile to the customer" by creating web-apps which entail all relevant information for customers in their given sales stage. Welcomy enables its users to rapidly create customer-centric web-apps that combine all relevant solution such as software solutions, sales- and marketing-relevant files, contact information, presentations and other documents etc. at their respective sales stage. Further, we developed specific, GDPR-compliant tools, such as a lead-collection tool, a digital product & services tool and an automized whitelabeling and translation feature. Overall, our solution can be shared with the target group or specific decision makers via our unique QR-Code or Short-URL sharing features.
