Tom from The Mission Motor here (have also done some more general M&E consulting in the EA space).
In my opinion, there is a lot of room for growth in M&E best practice in the (non-global development) EA space. There is often an appetite for M&E, but there is a real lack of knowledge and expertise. This to me presents a big opportunity where behaviour change is needed and also easier to obtain (though still not easy).
You can also have a snowball effect if you change the norms in the EA space. Personally, I feel like current concepts of measuring progress and impact in (again, mostly non-global dev) EA spaces are rudimentary. For example, we tend to focus on speculative cost-effective analysis as the primary method of assessing projects, even when they are still in the ideation phase. I believe this is, at least in part, because there is not an understanding of alternate M&E tools (e.g. setting up a good monitoring system for evaluating a theory of change).
I exclude the global development space as ideas from groups like IPA and IDInsight have permeated more there.
So my opinion would be strongly pro-working with EAs.
Reminds me of 2019, strongly upvoted and sent to a few people.
Some thoughts that come to mind:
Thanks for your upvotes and ideas!
Our business model is not yet refined, as we currently have funding and are able to be very flexible regarding rates depending on what makes sense individually. For us its important to maximize impact also consider the counterfactual while making pricing decisions. So I can't really give you a concrete answer at this moment in time, but if you want to get in touch, please do so!
