Most people wait around to be included in something. Builders create the room instead. You don't need a title for this and you don't need a budget. You need a purpose and enough nerve to invite someone in.

Name the purpose first. A vague reason for gathering people attracts the wrong people, or nobody at all. Then curate instead of broadcasting. Eight to twelve people beats fifty, every time. I'd rather have a smaller room where everyone actually talks than a big one where nobody does.

Design the first ten minutes on purpose, because how people walk into a room sets the tone for everything after it. And ask a question nobody expects. The obvious icebreaker gets you small talk. A better question gets you the real conversation.

Then create a reason to return. The second gathering matters more than the first one does. Anyone can throw one good dinner. Building something people come back to is the actual work. A dinner table, a group chat that actually talks, a standing call with two or three people, a co-working morning. Your table is infrastructure, even if it doesn't look like it yet.
