dehaze is building proprietary AI infrastructure to identify risks of chronic diseases earlier and more precisely on already existing health data. We save integrated health insurance companies 10% of their health spend and help patients live a healthier life. Our proprietary technology works where others can't: on unharmonized already existing health data. Founded by 3 serial entrepreneurs, we are backed by institutional investors and operate across Brazil, with expansion into the US and Europe planned.
