Why Keep? Because friendships need care.

Loneliness is one of the great quiet crises of our time. We built Keep so the people who matter to you don't simply fade out of your life.

Loneliness is not a personal failure.

Loneliness affects every age group, and it is growing. It rarely means someone knows too few people. Usually what is missing is closeness to the few who really matter.

The research is clear: good relationships are among the most important factors for a long, healthy and happy life. Without them, it is not only our mood that suffers, but our health too.

Our wish for friendship hasn't changed. Our everyday life has.

Friendships rarely end with a fight. They get quieter, until “We really should catch up” has turned into a whole year.

  • Fewer shared routines

    School, university or a sports club used to bring us together automatically. Afterwards, every meetup has to be planned on purpose.

  • Fewer third places

    The corner pub, the sports field, the café: places where you simply run into each other are becoming rarer.

  • Busy weeks, new cities

    Work, family and moving leave little room. Nobody leaves on purpose, you just reach out a little less.

Friendship takes time.

A study from the University of Kansas measured how many hours together it takes for acquaintances to become friends. Friendship doesn't come from one big meetup, but from many small moments.

Nobody can be close friends with everyone.

Anthropologist Robin Dunbar showed that our social world is built in layers. The closer the circle, the fewer people fit into it and the more time they need.

  • 5Intimate: family and closest friends
  • 15Personal: close friends you count on
  • 50Social: friends and colleagues
  • 150Public: casual acquaintances

Keep uses exactly these four circles. Each comes with its own contact rhythm. More about circles

The way back to the fire.

You don't beat loneliness with more followers or endless group chats. You beat it by looking after the few relationships that hold you. That is exactly what Keep helps with.

  • Reminders in time

    You decide how often you want to hear from someone. Keep nudges you before a few weeks turn into a year.

    More about reminders

  • See where you stand

    On the campfire, every friend sits as close as your contact is recent. You see right away who needs some warmth.

    See the campfire

  • Remember what matters

    Birthdays, important dates, notes and gift ideas. So you know where you left off next time you talk.

    All features

  • Build new friendships

    New acquaintances need regular contact too. Set a rhythm and keep at it until acquaintances become friends.

    Take the friendship test

Not a CRM. A place for friendship.

Personal CRMs treat friends like sales leads. Keep treats them as what they are: the people who make life worth living.

Personal CRMs

  • Track “interactions” like metrics
  • Optimize for networking value
  • Complex fields and pipelines
  • Built for professional gain

Keep

  • Remembers what matters to your friends
  • Helps you show up reliably
  • Calm, simple and without a feed
  • Built for real friendship

Why we built Keep

We kept forgetting birthdays. Important moments. The details that matter. Not because we didn't care, but because life got busy and the small things slipped away.

So we built Keep: an app that helps you show up for the people who matter to you. Because when you are there for others, they are there for you too.

“The only way to have a friend is to be one.”
Ralph Waldo Emerson
