Love it. To give some additional ideas, given social impact projects don’t always have equity (e.g., nonprofits), other possible ideas to give cred include explicit acknowledgement on the website (like with credits or thank you’s in movies, reports or books), being named a partner or a Board seat. Also, it would be cool to have a GitHub like website for social impact projects— that kind of cred is another powerful way by which engineers can point to a tangible example and proof of record of their involvement.
