I suspect that there's potential for a reskin of the notion of the "fraternal organization" that could work for contemporary urban professionals.

The way this would work is, you have a club, with dues-paying members. Invitation-only, and there's a process to get accepted. Members have to demonstrate high integrity and basically having their lives together: professional success and stable family are good.

Now you can do value-creating things with this group of trusted people that you can't do otherwise. For instance: members must provide professional services (like legal advice) free of charge to other members.

Dues can pay for a house (or ideally several in several cities) to host social events for the organization and offer free accommodations to members visiting from out of town.

Membership can also involve high-trust financial resource sharing, like a communal pool that offers interest-free loans to members whose loan applications meet the organization's approval.

You can add lots of community activities onto the basic structure -- a daycare co-op, charitable work, a lending library (books or tools), various hobby/social activities, as you prefer.

Unlike a professional organization, alumni organization, or college fraternity, this goes beyond providing a network; membership comes with formal obligations to contribute resources to other members. So it has to have a higher standard of trust than mere "networks".

Of course, it's a lot like a church, except it's for secular people. A combination of ceremonies and aspirational ideals, like the Freemasons have, wouldn't hurt either. Maybe give it a "systems thinking"/"ecological"/"integrative" flavor.
