I hear this question a lot in Cancún, usually in a low voice: “is it really worth paying a membership to go have breakfast with people every week?” Behind it is a fair suspicion: it sounds like a club, it sounds like a fee, and the result doesn’t show up on next month’s statement.
I went looking for what the data says, especially from the United States, where this model has been running for forty years and is measured. Here’s what I found, including what doesn’t add up.
The number everyone quotes—and what happens when you divide it
BNI, the world’s largest business referral network, published its mid-year report in August 2025. Their figures: 26.400 million dollars in business generated among its members over twelve months, through 17,4 million referrals, with more than 340.000 members in 11.400 chapters across 76 countries.
Huge numbers, and they get cited everywhere. But a big number only helps if you break it down. Let’s do it:
26.400 million divided by 340.000 members comes out to about 77.600 dollars per member per year.
BNI’s base fee in the United States is roughly 539 to 699 dollars a year, and 700 to 1.500 if you add sign-up, breakfasts, and events. Which means their own figure implies a return of fifty to one hundred times the cost.
And this is where a little skepticism helps, even though the stat is in their favor. That average doesn’t describe a real member. It’s a mean, not a median: a handful of law firms or builders landing six-figure contracts can pull the mean up and make it unlike what happens to the photographer or the nutritionist at the table. In fact, the number that shows up in independent reviews for the typical member is around 12.000 dollars a year, six times lower than the average from that division.
Both things can be true at once, and that’s the point: the mean measures the table; the median measures your chair. When someone sells you a membership with the big headline number, ask for the median for your chapter and for your line of work.
What independent research actually says
Setting aside the people selling memberships, there’s serious research—and it says two concrete things.
One: growth doesn’t come from “working the room,” it comes from belonging to something formal
Löfsten, Isaksson, and Rannikko published in 2022, in the Journal of Technology Transfer, a study of 241 new tech companies founded in Sweden in 2013, tracking their growth from 2014 to 2016.
The finding: formal ties—regional partners, incubator networks, links with universities—do have a statistically positive relationship with early growth. And a detail that undercuts a common belief: geographic proximity on its own wasn’t significant. Being surrounded by companies doesn’t make you grow. Belonging to a structure does.
Put in our terms: going to a mixer where you don’t know anyone and handing out cards is not the same as sitting every week at the same table with the same twelve people who already know what you do. The latter is a structure. The former is a pleasant evening.
Two: business doesn’t come from your close friends; it comes from your acquaintances
In 1973, Stanford sociologist Mark Granovetter published The Strength of Weak Ties, showing that most good opportunities don’t come from close friends but from more distant acquaintances. The reason is simple: your close friends move in your same circle and know what you know. The distant acquaintance sits elsewhere and sees what you don’t.
For fifty years that idea was respected theory but lacked causal proof. Until 2022, when a team from MIT, Harvard, Stanford, and LinkedIn published in Science the largest experiment ever run on this: 20 million LinkedIn users, five years, 2.000 million new connections, and 70 million job applications. They actually manipulated the “people you may know” algorithm to suggest closer contacts to some users and more distant ones to others.
Result: weak ties win. But with a nuance that’s worth its weight in gold: the relationship is an inverted U—the most useful aren’t total strangers but “moderately weak” ties, roughly ten mutual connections.
That’s exactly who you meet at a networking table: not your friend, but not a stranger either. They share context with you and still move in a different circle.
So, does the membership pay for itself?
It depends on one thing you won’t find in any brochure: the timeframe.
Independent reviews agree you need six to twelve months of relationship-building before real referrals start to show up. And there’s an old but telling data point: a 1993 study found that the likelihood of receiving one hundred or more referrals practically doubled with each additional year of participation.
In other words: this isn’t a lead list; it’s a slow instrument. The person who comes in expecting results in month two leaves in month three and decides it doesn’t work. The one who’s sat in the same chair for four years has a machine you can’t buy with advertising.
How to tell if yours is paying off
If you’re already in a group or thinking of joining one, track these four things. They’re enough, and you can keep them on a single sheet:
- Referrals received and referrals given, per month. If you give zero, you’ll get zero: this runs on reciprocity, not attendance.
- How many converted into clients, and how much revenue they generated.
- Total real cost: dues, breakfasts, events, and—the one no one counts—the hours. A 90-minute weekly meeting is about 78 hours a year.
- How long it took each referral to turn into revenue. That number tells you if you’re measuring too soon.
With that, in twelve months you’ll know if your chair pays for itself. Without it, you’ll decide by feel—and how January feels is nothing like September.
My takeaway from all this
You should always break down the big numbers used to sell memberships. But the independent research—with nothing to gain—points the same way on two fronts: what drives growth is formal, sustained belonging, and business arrives through the layer of acquaintances, not friends.
A paid networking group is, at its core, a machine for regularly creating moderately distant acquaintances on a schedule. That’s hard to engineer on your own—and it’s exactly what the research flags as valuable.
The fee doesn’t buy clients. It buys structure and consistency. The rest is on you—and it takes time.
