Gotta say, excited about this and how you've put this together Tightknit team 
A few thoughts/comments:
Momentum feels like a big jump for a bootstrapped product founder (definitely ok for early startups at seed+). At bootstrapped you're capital is thin to none. I think Growth could be a better starting point for many sticking their toes into the water of community.
My side hustle at https://jobtrawlers.com would be a great fit for this, but I'm honestly maxed and the idea of another surface to manage (even though I've used Tightknit multiple times, worked in the community space, and love what it brings to a product) — feels like too much right now as a solo bootstrapped founder with a full-time day job too.
What could a skinnier version of this look like? — maybe it's the 4 weeks of programming to level up founders and get them thinking strategically about how and when community can fit in best
Wonder if an idea here could be a combo of early startups and bootstrapped product founders alongside graduates of a "build your first community" cohort that could help those founders execute on and run their communities (even lightly part-time) when capital is tight and resources thin
