This product is extremely valuable for leaders trying to understand and improve the teams they're working with. There are three different products, each of which provides particular insights into the ways you work together. And certain exercises are highly configurable, allowing you to evaluate some of the unique characteristics of your group.
I've used the product with my team multiple times, and it's been incredibly helpful both for me and my teams - we've received really positive feedback about using Accompany.
In terms of return on investment, it's a no brainer for a team retreat, as well as for continued use. I'd pay significantly more for this, even as a very small startup - basically the product does nearly all of the legwork of helping you 1) figure out the right questions to ask your team 2) execute the process of gathering that data; 3) understanding how to interpret the data and facilitate a conversation around it.
