Sixty

Sixty is an AI assistant that manages incoming email, meeting invites and alerts so users are interrupted only when something matters. It works in the background of a user's devices and is positioned as a personal relationship management tool for people with heavy communication loads. The core features are briefings, agendas, email, alerts and outreach. Briefings give a single document before a meeting that summarizes past communications and background on attendees. Agendas are short emails summarizing the day or week. The email feature filters inbox noise down to what is important, alerts flag last minute schedule changes only when they affect the user's day, and outreach prompts users about birthdays and milestones of people in their network, with options to send a greeting or gift. The vendor describes the platform as free, and the site does not publish any paid plan prices. Sign up is through a signup link on the site. The company has announced a $3.5 million seed round led by 468 Capital, and the site's messaging centers on reducing interruptions and recovering time, including a Take Back Your Time movement it promotes.
