I've recently become curious about the scene, and discovered quite a bit going on. It seems most tech coops are operating more like agencies, taking on client work. Haven't seen many developing products.
Here is a great list of tech coops: https://tech-coops.xyz/
Here is a new but somewhat active matrix channel where some tech coops folks hangout: https://matrix.to/#/#techcoop:autonomic.zone We plan to have an informal call to chat there on 22nd of February at 17:00-18:30 UTC.
Here is a Discourse forum for tech coops: https://community.coops.tech/
Note that a big problem with building a product tech coop is that you exactly can't as easily raise millions: investors by definition cannot take stake in a coop. Instead, you need a business loan, and its less common to find financiers willing to loan large rounds for high risk investment. That may be a cultural thing though, because in theory, sufficient interest could offset the risk in aggregate I guess.
