I've worked on a synch+asynch voice platform for financial traders called a trading turret[1] and on collaboration tools for military and education. I've seen quite a few voice systems used factories, construction, and other worksites. Voice comms are a critical cool for many jobs that predates (and will likely outlast) typing on keyboards.
However, I'm trying to imagine who would use this product.
It's deskbound (until 2027 it looks like) so that rules out worksites but is far too constrained (and pretty) for traders and military use. You list "product development", "leaders", and "international teams" as potential roles, but as evidenced by the responses in this thread, many people who do product development treat synchronous voice comms as an abomination. The closest I can imagine would be call centers -- helpdesk, marketing, support, that sort of thing.
I'm very curious how much user research and long-term usability testing you've done with real teams trying to get work done. If not much, I'd suggest making that a high priority. I apologize for how harsh this sounds, but my initial gut reaction is that this is a typical Silicon Valley product that pairs wonderful industrial design and engineering with a complete ignorance of other people.
