Found the group
Founding a group just means deciding what it's for, then personally inviting the first handful of men. A group doesn't need a polished program to begin. It needs a clear purpose and a few committed men. Just showing up together is itself the medicine [1], so your first job is simply to get men into the room on a repeating basis.
Name the purpose in one sentence before you invite anyone. Something like "a regular place for men to be honest and not alone." Keep it about connection, not fixing or curing. Men can smell a self-help project, and most will run from it.
Invite face to face, or by a direct personal message, one man at a time. A personal ask from a man they trust beats any open flyer or group blast. Aim to land 4 to 6 men who'll commit to the first few meetings. Starting small works because trust forms faster in a small room, and a handful of reliable men is a stronger foundation than a big list of maybes.
Lower the bar to entry. Frame the first gathering around a shared activity or a meal, not "a support group." Men who'd never attend "group therapy" will happily show up to build, eat, walk, or fix something together.
Make the invitation concrete. State the day, the time, the place, who else is coming, and how long it runs. Certainty removes friction. "Thursday at 7, my garage, four of us, done by 8:30" is far easier to say yes to than "we should hang out sometime."
Name your own reason for wanting this. A little honesty up front ("I've been feeling disconnected lately and I want something better") signals what kind of room it'll be, and gives the next man permission to be real too.
