Watefy makes CLEAN AND HEALTHY drinking water by adding vital minerals calcium, magnesium, and bicarbonates. WATEFY is a startup that invented novel technology to make water healthy for humans, animals, and useful for agriculture. WATEFY brings the solution to the acute global Problem – MAGNESIUM DEFICIENCY that causes severe illness, diseases, and death of millions around the world, in developed and developing countries as well. The associated annual costs in the EU and the USA are more than 1 trillion US$. The Solution: Rising magnesium quantity in drinking water to 20-30mg/L dramatically improves the health of the population of all age and social groups. Watefy ambition is to make the Best Quality and Healthy water accessible and affordable to Millions of People around the world. The Technology: Watefy succeeded to harness little-known processes of developed hydrodynamic cavitation to realize efficient physical and industrial processes to enrich water by essential magnesium bicarbonate. Product: Watefy developed 3 Product verticals for different markets: • Water Mineralization Systems for seawater desalination and drinking water conditioning utilities; The market volume – US$3B; This niche will grow fast with growing the demand for drinking water. Watefy systems are X30 smaller, and X10 lower cost in CapEx, and 50% cheaper in OpEx vs the benchmark – calcite contactors, which besides all its cons, are able to add to water calcium only. There is NO available technology able to add magnesium to the water. • Systems for “ man-made” mineral water for the Bottled Water market niche: US$250B, and growing at 10% annual rate; Absolutely new product on the market: top quality at a fraction of present prices. The manufacturing can be set at any location; • The customers – grocery chains, which do not have their sources of high-quality mineral water (actually, no-one has!) and willing to sell mineral water under their private labels under the Licensing. • ·Novel Water Appliances (residential and commercial) to make 24/7 clean and healthy drinking water containing essential minerals. Hot/cold/carbonated water of the quality of the best global brands. Low cost of “made” water, its availability, and drastic reduction of use single-use plastic bottles. The new market assessed at US$5B, one-of the kind appliance to meet the consumers' demand for low-cost high-quality water at home. All 3 Products will be marketed in the NO-COMPETITION environment.
