This might be a cool product but the website make the user work to understand what is specifically you are offering and how to actually get going with using it. Maybe is feature a not a bug where you want only super interested people to test it?

First problem is why is the demo video 30+ mins long? Make it 3 mins at most (even that is too much).

ActionStitch reminds me of the camera that goes up poles that was also marketed for youth and non pro sports. Was on HN (a few years ago?). That was hardware, but same vibe.

"The most affordable high-quality 180° sports video recording" What are the current solutions to get the same result now?

All this being said from casual glance it looks good, can't tell its two cameras.
