Maybe it's not as important to know the owners, s to know about their experience and the intentions.
You are talking to the owner. So feel free to get to know me. You can ask anything you want. I like good questions.
It might be not important to you but knowing the background of the team, especially to the owner will give you a glimpse of what this project can reach it the future with their past experiences might be successful one or they surpass some challenges that will help them to plan well that will help a lot too in making the right decisions for the project.
