There's also the PBC (Public Benefit Corporation), which in addition to profit / shareholder value explicitly defines positive impact on society as a goal, and exists since 2010 in some states, while in others only since 2022 [1]. But as far as I understand there are no legal requirements or audits that ensure those goals are followed.
Kagi (the search engine, popular in the HN community and I'm a happy customer myself) is one example of a PBC [2].
