Quick update: I'm still looking for this — I believe based on preliminary research that setting up a the benefit corporation is the way to go, so if anyone has any experience doing this, particularly in Massachusetts, USA, I'd be grateful to talk to you. 

Thanks, Larks. I'd prefer to talk directly with folks who have first-hand experience on the topic. I was thinking that afterwards, I might summarize what I learn going through this process and post that information after to help anyone else with a similar decision to make.

Thanks, Jason. Jurisdiction would likely be Massachusetts USA, but potentially Delaware USA.

The main purpose is to understand the financial/legal ramifications of each structure. For example, I know nonprofits can sell services but I'd like to better understand how it works from a paperwork perspective. Similarly, I'm interested in better understanding what overhead would be involved in both options - what exactly would need to be reported and how often, etc. Some of this I'm in the process of answering myself via online articles, but I'd like to talk with someone who has first-hand experience to ask more nuanced questions and confirm my understanding based on my initial research. 

I discussed this in a bit more length in this conference here (https://www.youtube.com/watch?v=sivsXJ1L1pg), and in this paper: https://arxiv.org/abs/1809.01036.

The two links in this paragraph are broken; I'm interested in taking a look, are the resources still available?

Glad this edit was included at the start of the post; it definitely helped me as I read through the ideas. Thanks!
