Has anyone run local events with a WhatsApp community or Slack with Tightknit for CFOs?

Hi everyone! 👋 I'm a customer marketing manager at a B2B fintech whose community is aimed at CFOs and finance leaders. We ran our community on Circle for about a year, but engagement never really took off, so we're rethinking the format. Two directions we're weighing: 1. Local events + WhatsApp community. We'd recruit local ambassadors among our customers and grow the community through their networks, by organizing small events like dinners. Has anyone run this model? I'd love to hear what worked, what didn't, and how you kept the WhatsApp side from going quiet between events. 2. Slack + Tightknit. Probably a biased crowd to ask here 😄 but I'm curious how it performed for a senior, time-poor audience like CFOs. Thanks in advance!
