The FinTech company troy is changing the traditional debt collection industry with methods from marketing and CRM. The aim of the start-up with the locations in Lippstadt (NRW) and Hamburg is to maintain the relationship between the company and the customer in addition to the realisation of the receivables. The founders of troy, Philip Rürup and Till Völzke, rely on multichannel communication as well as individualized and data-driven communication in combination with decades of debt collection expertise. The mission: troy becoming the most customer-friendly debt collection company in Europe.
About half of consumers are in default of payment due to forgetfulness or short-term bottlenecks. Despite that, traditional debt collection treats these customers as if they have not paid intentionally. The process is impersonal, bureaucratic and unpleasant. It is obvious that as a result, companies usually lose their customers. troy changes this and continues to treat the customer as a customer. Tried and tested methods of multichannel CRM, targeting approaches and machine learning drive the new approach. troy addresses each customer via the most promising mix of communication channels and with individually adjusted messages. High transparency, multiple payment methods and friendly communication add to the “troy way”. This allows for high recovery rates of both receivables and customer relationships.

These interactive guides lead every user through all processes and show them real-time where to click next within the software – just like GPS navigation systems in cars advice drivers turn-by-turn how to optimally reach the destination. This way complex software can be easily used, without previous knowledge, making extensive software training obsolete.

VACIS is the leading tissue engineering company for body-own blood vessels.
The VACIS technology uses a synthetic rod which induces the formation of a new fully functional blood vessel providing novel therapeutic options for vascular surgery. Prosthetic vascular graft failure is a frequent complication in vascular surgery with substantial morbidity and health care costs. VACIS provides patients autologous graft vessels, with sustained patency and fewer complications requiring less corrective interventions.
Vascular grafts are needed in many areas of medicine. VACIS initially focuses on vascular access in patients undergoing hemodialysis. Other indications will follow after clinical validation of the technology in hemodialysis. Such other indications include peripheral arterial occlusive disease.
VACIS provides an advantage over other therapeutic options in the hemodialysis access market. Current solutions have a low patency: many arteriovascular fistulas fail to mature or no adequate vein is available; the foreign material in synthetic grafts lead to infection, stenosis, thrombosis etc. and the synthetic material does not heal after cannulation.

WMT developes small molecules for cancer indications by targeting the Warburg Metabolism. The Warburg Metabolism was first described 100 years ago by Otto Heinrich Warburg and the therapeutic approach is based on the fact that many cancer cells predominantly produce their energy through a high rate of glycolysis followed by lactic acid fermentation even in the presence of abundant oxygen. Using this mechanism for the treatment of cancer turns out to be very difficult, as interventions targeted at the sugar metabolism also cause harm to healthy cells. The approach WMT is using offers an improved therapeutic window as opposed to classical cancer medicines.
