Of DAO's funding/incubating projects? shinedao does (though mostly revenue generating focus for now, although those projects can have r&d components, haven't seen pure foss dao's but i dont know everything going on in the space), probably others.

Of decentralized lending protocols? aave, compound, benqi, etc.

I was wondering about pure foss dao's or even closed ones. Anything to do with software, a service or even hardware.

Ahh, yeah don't know any outside of those that make specific defi protocols that are at least GPLv3. I'm deff interested in being apart of something like it in the future with shinedao (maybe being incubated by them in the future, anyone is free to join and put forth an initiative to the community to gauge interest though, for this or any other project), I just don't know of many people are the same and can actually contribute via code and also in the defi ecosystem (there are a few software devs and even hardware engineers in the community, but many more who aren't), but I think it will be a natural progression from all the GPLv3 stuff being put out there related to web3.
