Sixty

Sixty is an AI productivity platform designed to help professionals stay in touch with their network and manage their time without wasting effort on tasks that AI can handle. The product handles inbox management by surfacing only the most important emails and clearing noise, provides automated scheduling with daily and weekly agenda snapshots, generates meeting briefings that summarize all past interactions with attendees, and sends real-time alerts for last-minute schedule changes. Sixty also offers an outreach feature that tracks birthdays and professional milestones across a user's network and makes it easy to send timely, personalized messages or gifts. The platform is positioned as a relationship intelligence layer on top of a user's calendar and email. Sixty is headquartered in Portland, Oregon.
