We are just a team of software developers, not company or another legal entity. Although we are actively developing our product, it's still not ready for demonstration. However, we are a little far away from the problem domain and we would like to gather feedback from real companies who are our potential clients, to align our product vision with client's problem vision.
We found a company who is ready to look at our product/idea and give us feedback. Because we don't have a real product yet, we have decided making a video presentation with questions at the end. However, we have a zero experience in this type of activity.
How can we gather feedback about a product that isn't ready to demonstrate yet?
