> library and technology choices made across the entire App Store. I figure this would basically be killer for e.g. sales teams at API companies, analysts following them You nailed it, Patrick, and I wish I talked to you sooner. We were collecting this app data at MixRank for a while before it occurred to us to track every SDK and API integration. It turns out that knowing all the integrations an app has (ads, analytics, social, cloud services, tracking, libraries, etc) is really useful for predicting and understanding your customers! > Do a for loop over your customers and profile as many signals as you can. The most effective signal is the most obvious one: Did the app just integrate my competitor's SDK? This usually means the app is in a trial period and still deciding— you couldn't ask for better timing. Next best is: Did the app just uninstall my competitor's SDK? Then they're likely unhappy and searching for alternatives. (Source: we work with a bunch of sales teams that use us for exactly this)
