Why 142? The story behind the number

It is the first question everyone asks, usually within about ten seconds. Why 142? Why not 150, or 100, or no number at all?

It is a fair question, because the number is not branding. It is the entire product. Every other decision we have made, the chronological feed, the 30-day expiry, the absence of follower counts, only works because of the cap. So the number deserves a proper answer, and this page is it.

Why a cap at all

Start with what happens without one.

A network with unlimited connections has a problem: the list grows and never shrinks. Colleagues from two jobs ago, someone you met once at a wedding, accounts you followed for reasons you no longer hold. Within a few years, the people you actually care about are a minority in your own feed.

At that point the network has to make a choice. Either it shows you everything in order, which becomes unusable, or it builds an algorithm to guess what you want, which is how every feed you have ever lost an evening to got started. The algorithm is not the original sin. The unlimited list is. The algorithm is just the repair job.

A cap removes the need for the repair. With at most 142 people, a chronological feed works on its own. There is nothing to rank, nothing to optimise, nothing to guess. The feed shows you what your people shared, in order, and then it ends. We did not build 142 without an algorithm to make a point. We built it with a cap, and the algorithm simply had no job left to do.

Where the number comes from

For decades, researchers have studied how many relationships a human being can actually maintain. The best-known figure is around 150, often called Dunbar’s number after the anthropologist Robin Dunbar, who found it recurring everywhere from hunter-gatherer villages to military units to Christmas card lists. It is an average, not a law, and the academic debate around it is livelier than most articles let on. But the underlying finding is hard to argue with: meaningful relationships take time and attention, both of which are finite, so the number of them you can keep is finite too.

So why not just use 150?

Because the number was never chosen off a chart. It was found in my phone.

Before there was an app, there was an evening with my contact book. I had read the research and wanted to know what my own real number was, so I opened my contacts, somewhere north of 400 names, and started deleting. School friends I had not seen since school. Colleagues from roles I left years ago. Names I had to think hard to place, and names I placed instantly but had simply drifted from, no falling-out, no story, just time. I removed every name that was an archive rather than a relationship.

When I stopped, the count read 142.

I would love to tell you that was pure method. But my favourite number is 42, for the reasons you would guess, and it is entirely possible that some part of me saw it appear and decided the cull was complete. I genuinely do not know. I have made my peace with that, because both halves are true to what the product became: a cap grounded in decades of research, discovered in one real address book, by one person working out who was actually still in his life. If it carries a small wink in the last two digits, all the better.

What matters more than the precise figure is what it represents: the outer edge of the people who are actually in your life. Not your audience. Not your industry. The people you would genuinely greet at a wedding or miss at a funeral. For almost everyone, that group fits inside 142 with room to spare.

Why the cap is hard

Plenty of products have flirted with limits. Almost all of them flinch.

Path, the much-loved private network of the early 2010s, launched with a limit of 50 friends. Then it raised the limit to 150. Then it loosened it again. Each move made commercial sense at the time, and each one quietly dissolved the original promise, because a limit that moves is not a limit. It is a waiting list. We wrote the full story in what happened to Path, and it shaped this product more than any success story did.

So the 142 cap is hard. It does not rise for power users. It cannot be expanded for a higher fee. It is the same for every person on the network, including me. We are confident enough in this to have named the company after it, which is a useful way of making a promise expensive to break.

What the cap changes in practice

The cap sounds like a restriction. In use, it works more like a guarantee.

It guarantees that everyone who sees what you share is someone you chose, recently enough to remember choosing them. It guarantees that growth is never the goal, because there is nothing to grow. There are no follower counts in 142, and the cap is the reason that absence feels natural rather than missing: counting makes no sense when the ceiling is the point.

And it changes what sharing feels like. Posting to an unlimited audience is publishing, with everything that implies: the second-guessing, the performance, the wondering who saw it. Posting to your 142 is closer to talking. The photo does not need to be good. It needs to be yours.

Reaching the cap is rare, but the rule there is simple: to add someone new, someone has to come off the list. That sounds brutal written down. In practice it is just the honest version of something every person already does silently, which is decide who is in their life now. We think making that choice deliberate, occasionally, is healthier than letting a list grow stale forever.

The number is the promise

A subscription network lives or dies on whether it keeps being worth paying for, and the cap is the heart of that bargain. It is why the feed can stay chronological, why there is nothing to farm and nobody to perform for, and why no version of 142 can quietly drift into being another attention machine. The full argument for that structure is in our guide to private social networks. The short version is the name on the app.

Summary

142 is named after its cap of 142 connections: a number grounded in the researched ceiling of around 150 meaningful relationships, and found in practice when the founder culled his own contact book from 400-plus names down to the people genuinely still in his life. The cap is the product: it is what lets the feed stay chronological, what makes follower counts pointless, and what keeps the network from ever drifting towards an audience. It is hard, universal and not for sale, and the company is named after it so that walking it back would cost us the brand. The number is not a gimmick on top of the idea. It is the idea.
