Nautis is an AI-native operating system designed for startups, functioning as an AI Chief of Staff. It centralizes a startup's operations by maintaining a unified workspace that tracks numbers, deals, investors, deadlines, and documents. The system operates on an approval-based workflow, preparing actions and briefs for the user to review and authorize before any action is taken. The platform organizes a startup's weekly priorities into four primary areas: Focus, Pipeline, Revenue, and Watch. It maintains a live Company Brief that is continuously updated from connected data sources such as calendars, inboxes, and documents. Nautis states that user data remains within the workspace and is not used to train external AI models. It also offers integration with WhatsApp for communication. Typical use cases include daily briefings, meeting preparation, investor pipeline management, and revenue tracking. The tool is intended to reduce the time spent switching between disparate applications and re-explaining business context to different tools. By consolidating information into a single living brief, it allows users to start their day already caught up on key metrics and action items.
