Ask HN: Launch accountability competitions similar to Startup School or Pioneer?

I find that participating in competitions where regular updates help accountability and also provide an opportunity to engage with a community that has similar goals - launching a product - is helping me a lot in my journey.

On the basis of "I don't know what I don't know" I'm curious if you can recommend any other places where I can participate in such communities?

Currently I am active on Startup School and Pioneer. Indiehackers and Makerlog also seems fine, but I feel like the regular, weekly update schedule is probably the best fit for me and the eventual reward at the end of the tournament is also a motivating factor.

I assume other funds / accelerators also host similar stuff.
