Composer

There's almost zero public signal on Composer right now, which makes sense if it's early, but here's why it caught my attention: most markdown tools are solo acts, and most "collaborative" docs are either Notion-style wikis or code-first IDEs. Composer is explicitly positioning itself for you, your team, AND your agents — meaning they're betting that the next wave of document workflows isn't just human-to-human, it's human-to-AI-to-human. That framing is different. No founder name, no numbers, nothing shipping yet, but the thesis is sharp. Keep an eye on this one if you're tracking agent infrastructure tooling.
