I should preface this suggestion that I am entirely onboard with Enscape, our firm loves it and our clients and partners love it. I think its an incredible tool and it sets the bar for how software developers should operate.
I recently came across a software called Modelo. (https://modelo.io/). It operates on slightly different principles (uploading models, no modeling plugin functionality with sketchup/revit etc) from what I can tell it's essentially a geometry viewer with some lighting/shading capacity. The presentation visual style is rather underwhelming - they could learn a lot from you guys. However, visual style aside, they have nailed a lot of collaboration features that may be of interest to the Enscape team. Things like walkthroughs, commentary, notation etc. see attached images.
I am not trying to plug their product or put down enscape, I think that both of your teams are addressing different sides of the same problem; perhaps both teams would benefit from sharing, and obviously all users would benefit enormously.
Thanks Enscape and keep up the good work!!
