I'm very sympathetic to cooperatives, have traveled/know the Mondragon people (largest coop federation), etc.

However, I think there's a reason why coops seem to succeed at smaller scales, but there are essentially no large innovative coops.

There are a few large boring coops, and some small innovative ones, but seemingly something is making the CEO/investor board model the one large innovative companies are all using.

I suspect that it's both (1) access to capital is far harder for coops, and (2) that workplace democracy and hardcore mission focus aren't fully compatible. That is, "you cannot serve two masters" without losing focus on one of them.
