Related, I started a rather successful tech meetup in Tampa, Fl. In just under a year we grew it to 1000 active members. We're expected to hit 30-50k revenue (possibly even higher) as a almost newly nonprofit next year that we're putting back into the community

If anyone wants to emulate this work for their own community, I've written a series of blog posts about the challenges I've had to solve along the way. For context I have about a decade of experience in startups and building communities, and have alot of awesome advisors more experienced than me guiding me through all of this
