Why isn’t there an app for that?

Life is busy; relationships are hard. We searched for the right tool for our relationships (yes, we tried Airtable!) but nothing was perfect.

These tools were manual, tedious, and hard to come back to. We decided to build a better solution.

Dex was founded in 2019, and we’ve been building ever since. We named it Dex because we're creating the simple, modern rolodex of today.

What we believe

  • 🔐
    Privacy

    We'll never sell or share your data. Your data remains yours.

  • Simplicity

    Dex isn't a sales CRM — there are no deals or pipeline here. We’re making Dex for relationships, not sales.

  • Speed

    Your life is busy enough. Intuitive interfaces + less data entry = more time with the people that matter.
