I’m guessing their “momentum” wasn’t on the path of building a sustainable business, particularly given the existence of Microsoft. From a market position standpoint, Paper could have become what Notion is now. Notion even released at around the same time as Paper. Was it that Notion from early on supported Markdown compatibility, which is a distinguishing feature when selling to software startups? Was Paper too aggressively coupled to Dropbox storage, when Google, Microsoft, and Box already had a large share of that market?
