Making friends as an adult isn't a talent — it's a routine: shared activities, repetition, and a bit of nerve. Here's the practical path, minus the platitudes.
In school and at university, friendships happened on the side: same rooms, same schedule, the same people every single week. Nobody had to arrange anything — the system did it for you. With your first job, that system disappears, and many people only notice years later that their circle has quietly shrunk.
Friendships need three core ingredients: physical proximity, repeated unplanned encounters, and settings where people can let their guard down. An office made of video calls, a new city, or a packed calendar provide exactly none of them. The problem is not you — it is the missing structure.
The good news: you can build that structure yourself. Recreate those three ingredients deliberately, and you will make new friends at 25, 35, or 45 — usually faster than you expect.
One-off encounters feel great but rarely turn into friendships. The lovely person from the party stays the lovely person from the party if there is no second meeting. That is why formats with built-in repetition work so much better: the weekly run club, the games night every other Thursday, the standing dinner table.
So don't plan to “go out more”. Pick one or two recurring activities and commit for eight weeks. By the third time, people greet you by name; by the fifth, there's an inside joke; by the eighth, it feels like a crew. That is exactly how your old friendships formed — except back then, the timetable enforced the repetition for you.
The easiest way in is something you enjoy anyway — sports, cooking, board games, photography. A shared activity removes the pressure: the topic of conversation is built in, silences are not awkward, and nobody stands in a corner with a drink hunting for the perfect opening line.
That is exactly what SUPA is built for: you see public activities in your city — from volleyball to going to a concert together — you see who's coming before you commit, and you join with one tap. The group coordinates in the chat, and “we should hang out sometime” becomes an actual plan with a time and a meeting point.
One: sports groups and run clubs — low barrier, built-in repetition, and shared effort bonds people. Two: games nights — two hours of laughing together beat ten rounds of small talk. Three: multi-week courses like a language, pottery, or dancing — seeing the same faces for weeks is half the way to friendship.
Four: volunteering — working on something together builds trust fast, and the scene is famously open to newcomers. Five: regulars’ tables and open meetups in your scene, from tech to bouldering. Six: your own neighborhood — the courtyard flea market, the sports club around the corner, the café that recognizes you after three visits.
Seven: use existing contacts — tell two or three people you're actively growing your circle and let them bring you along. Eight: a dog introduces you to more people in a month than most manage in a year. Nine: coworking instead of home office, one or two days a week is plenty. Ten — the most underrated: host something yourself. The person who invites never has to hope for an invitation. Even a simple walk with an open guest list makes you the center of a new circle.
After a move, the same rules apply — just compressed. The first weeks are gold, because everything is new and you are in explorer mode anyway. Set yourself a simple quota: one activity per week, however small. Consistency beats motivation.
Order matters too: find recurring formats first, big events second. A weekend festival is fun, but the Tuesday run club is what builds a circle. In Cologne, Düsseldorf, Bonn, Berlin, and other cities, SUPA lists open activities where everyone expects new people to show up — the city pages below are the fastest way in.
The jump from nice acquaintance to actual friend never happens on its own — someone has to make the next move. Let it be you: after an activity, make a concrete plan (“Same time next Saturday? I’ll post in the group.”) instead of a vague “see you around”.
The 48-hour rule works well: follow up within two days of a good meeting. Research suggests it takes roughly 50 hours of shared time for acquaintances to become friends — which sounds like a lot but is just one weekly meetup over a few months. Friendship is less magic than calendar.
Mistake one: staying online-only. Endless chats without meetings feel like progress but are not. Mistake two: giving up too early — quitting after two attempts means stopping right before the repetition threshold where friendships actually form. Mistake three: only going to huge events where everyone stays in the group they arrived with.
And the most common mistake: waiting to be invited. Most people around you would love more real connections — it is just rare that anyone dares to make the first move. Be the person who does. Usually, that is all it takes.
Research suggests roughly 50 hours of shared time to go from acquaintance to friend, and considerably more for close friendships. In practice: one recurring meetup a week over two to three months — not one perfect evening.
Most reliably through recurring activities: sports groups, courses, volunteering, regulars’ tables — or by hosting something yourself. After 30, spontaneous time is scarce, so fixed formats with a clear date win.
No — at open activities most people come alone, precisely to meet new people. On SUPA you see who's attending beforehand and can coordinate in the group chat, so you already know names when you arrive.
The one that gets you into a real meeting fastest. Pure chat apps produce many matches and few encounters. Activity-based apps like SUPA flip it around: the shared plan comes first, and the connection follows naturally.
