I've used Notion for around two years now, and I think it's a great tool for startups. It allows you to create Kanban boards, summarize meeting notes, and store documents. Notion is to Jira what Trello is to Asana—perfect for small teams without a project management background who need to organize team spaces and manage projects. However, as your organization grows, a more robust tool like Jira might be a better fit. For its intended audience, which I would say is small startups, Notion is ideal.
