Mapbox

Mapbox is a highly aggressive, fiercely modern, and massively disruptive "Developer-First Location Data Platform." While ArcGIS and QGIS are massive desktop applications built for GIS scientists, Mapbox is a suite of incredibly powerful APIs and SDKs built explicitly for Software Engineers. It powers the custom, highly styled maps inside massive global apps like Strava, Instacart, Snapchat, and The Weather Channel. The absolute core differentiator of Mapbox is its "Stunning Custom Vector Rendering and API Architecture." Standard Google Maps look like Google Maps. Mapbox allows a company's developers to inject massive amounts of their own custom data onto a map, perfectly match the colors and typography to the brand's aesthetic, and render millions of data points smoothly in a mobile app using highly optimized vector tiles. Furthermore, Mapbox provides staggering backend tools for "Turn-by-Turn Navigation and Logistics Routing." When a massive delivery company needs to route a driver through a complex city, they don't use a desktop GIS tool; their app makes an API call to Mapbox. For modern tech unicorns, logistics startups, and mobile app developers who need to embed elite, custom spatial intelligence directly into their own software, Mapbox is the undisputed titan.
