Ashamed to say I'd never heard of the phrase "social and solidarity economy" before today
"Solidarity economy or social and solidarity economy (SSE) refers to a wide range of economic activities that aim to prioritize social profitability instead of purely financial profits"
https://en.wikipedia.org/wiki/Solidarity_economy
Found in the following FOSDEM25 talk
"A Business Intelligence architecture for Social and Solidarity Economy."
