Title: Last year I launched a website that allow people to see rainfall statistics that are based on satellite data. Historical rainfall information usually comes from rain gauges, and while these are fantastic there are many parts of the world that don&#x27;t have many long term gauges, or where that data is hard to access. Satellite data can be an invaluable source of information for those data-scarce areas.<p>The business model is to sell &quot;extreme precipitation&quot; data that can be used for flood modelling. Unfortunately, after a year I still haven&#x27;t made a single sale. I&#x27;ve tried various ways of advertising, mainly via messaging people on LinkedIn  who would actually have a use for it. I&#x27;m still proud of what I&#x27;ve built, even if it&#x27;s a flop!<p>The tech stack is SolidJS with a Django API backend.<p>Fun feature: jump to a completely random part of the world by clicking the &quot;Random&quot; button.<p>I&#x27;d love feedback on anything, such as how to improve the UI&#x2F;UX of the mobile view of the map page.
