Thanks for taking the time to reply.
This proposal is not necessarily addressing how to get more builders to propose to the DAO; it is about forming a specific community (or subdao) of builders that have already gone through the vetting process of building with Nouns.
The problems I have outlined at the beginning of the document aren’t addressed by size of project – I don’t believe that the scale of the project proposed by a builder has a direct impact on their voice in the DAO or if they stick around afterwards. A solution to attracting builders and larger scale projects with future upside has been proposed in Retro Impact Funding
