If with revenue for year 2020 estimated between 745 and 768 million dollars they are still losing money then what are their operating costs? I am not familiar with how software as a service companies operators but if they are not manufacturing anything then their cost must be mainly development and operator salaries, and rent and such like. So what else is the money spent on? AWS? Google Cloud?
