What is
Dex
Dex is a personal CRM that pulls contacts from LinkedIn, email, calendar, messaging apps and phone into one place and merges duplicates. Each contact gets a timeline of meetings, emails and messages, with notes, tags and keep in touch reminders. It also sends pre meeting briefs and alerts when people in your network change roles, which helps founders and business developers keep relationships warm.
