So I spent some time with your application today, and there are some really good ideas in it. I definitely think this software category will be big one day so congratulations on the forward thinking.
That said, the product needs to keep reality in mind. 90% of my teams don't have VR headsets yet, and the web experience is just not good enough to come even close to a traditional meeting experience. You would be FAR better off building an integration with MS Teams, Slack meetings, Zoom, Hangouts, etc.
The other thing to keep in mind is that even if you do have a VR headset, the hardware is not comfortable enough for all day office use. I often have 8 meetings or more a day, I could not wish your product onto my company and imagine it meant having to wear a headset for that many hours. It would be exhausting.
So if you want to change the workspace, start with those practical realities in mind. We're not going to pay for a meeting software if meeting software comes with Microsoft or Google subscriptions we won't ever give up, unless it makes what we already have better. We're not going to pay for a meeting software for just 10% of our team.
The other way you can address the business problem is by focusing on niche user groups who NEED telepresence, like collaborating on a design. Imagine you worked with invision, or made it the ultimate interior designer software to demonstrate concepts to their clients remotely.
Good luck!
