Universal Diagnostics S.A. (UDX) is a Spanish in-vitro diagnostics company developing minimally-invasive, blood-based solutions for detecting cancer early when treatment options are more plentiful and survival rates are still high. UDX believes that the best way to fight against cancer is by detecting it early. The UDX diagnostic platform is designed to detect various cancer types, e.g. colorectal, prostate, liver, pancreatic lung, breast cancer (>50% of all new cancer cases p.a.) via one simple blood test. The assays rely on a curated set of proprietary methylation marker panels; a simple blood sample collected as part of a routine check-up, can be processed at a reference laboratory or hospital using standard equipment and then uploaded to the UDX Cloud for final algorithmic analysis. UDX’s first marker panel is a colorectal cancer screening test. The test identifies individuals who need to be referred for colonoscopy. Colorectal cancer is the 3rd most frequent cancer and 2nd deadliest cancer worldwide. The challenge is that colorectal cancer is mostly detected in late stages, with significantly decreased survival rates (11% survival rate in stage IV vs. 85% survival rate in stage I). To develop the test and execute its R&D and operations, UDX partners with international research institutions, hospitals, universities, and biobanks around the globe.

150 Charter S.L., under the operational name of aBoatTime & BoatGrid provides technology solutions and services for the nautical sector. It is the only complete ecosystem in the world that allows to connect, via Web 2.0 (real-time availability and online payment), end customers and mainstream tourism (touroperators and OTAs) to the fragmented sector of recreational boat chartering. This is possible thanks to the in-house development of: 1) a reservation management software for fleets (BoatGrid.com) – equivalent to SAP for hotels, 2) the only GDS (Global Distribution System) for boats to date – equivalent to what Amadeus is for flights-, and 3) a transactional website for end-clients (aBoatTime.com) – a real-time search and booking engine. Additionally, aBoatTime & BoatGrid offer integration solutions for B2C channels, such as web services or API connections, in-house development of white labels for channel websites, or an agency portal (BG World) for physical agencies and call centre teams. Our goal is to become the standard for the three categories on a world-wide basis, and make boat chartering a holiday alternative to the masses. Customer groups include fleets, travel sellers (tour-operators and travel agencies), and travel buyers (corporations, travel management companies and final clients). Our partners include Booking.com, Viajes El Corte Inglés or Halcón Viajes, amongst others. We have about 2,000 boats under contract in Europe and the Caribbean, an inventory that is constantly growing, and we have recently launched our Premium brochure for high-end yacht rentals (http://boatgrid.com/bgworld/banners/showDocument?nameDocument=premium_ES.pdf).
