There are no companies that rise meteorically, capture billions of users and then collapse if they can't monetize. There are just companies that quietly provide products and services users want. If that's considered a failure to you, then... okay? Signal is American, but Telegram is Russian. And you can just, you know, send a text message, without involving any third party (but both your phone companies can see it).
Oh and the b2b companies... like ASML and SWIFT.
