Creating a Sales Leaders community: tips?

Hello! I noticed there's tons of support groups / communities / even edtechs for technical audiences, yet relatively little for non-technical groups (apart from Revenue Collective in the USA, less impactful in other cultures - based in EU).

So I decided to pre-validate building a sales leaders community in Spain (initially), got started with a Tally.so form on social media - got 30 applications from great sales leaders in Spanish startups and spanish peeps at big tech companies - 90% of them happy to pay a subscription to be included in the group.

When interviewing them and listening to them talk the same value prop kept popping up.The initial idea was to launch an MVP, dead simple:

1. Slack group: get help solving day-to-day problems from peers, embedded.
2. Dinners: workshop centred around a business case / problem + a few beers

TWO QUESTIONS FOR YOU community-building aficionados :

1. SLACK STRUCTURE: what's the best framework / resource / template / ideas to setup a Slack group so that its actually valuable for a community like this?
2. DINNER / EVENT: any resource or recommendation on the best way to make an awesome petit committee diner or event?

Thanks in advance! 🙏
