They have pioneered some of the best state of the art light field rendering and worked with carmack in the past years making VR that much more viable in the future. Also they did"render the Metaverse" which was one of the best look into the future content competition there will be for quite some time.
Brigade is just waaaaaaay too young and the hardware two generations behind. I don't understand the push of it at all. There "realtime game renderer" city demo was demoed on a render farm with 50 GPUs.
And of course the main renderer. They are still the best at it and once you setup and get around the limitations, the fastest pathtracer there is. (disregarding redshift, dunno how far they came)
You may have caught onto the Vibe OTOY are giving. They are not interested in stable products, reliable office support and optimizing. Even on their Website they say "pioneering technology that is redefining content creation and delivery for media and entertainment organizations around the world." They pioneer, they try, they experiment.
So it does come off as vapor ware at times, they are indeed not too vocal on their inner workings. Their views barely align with the reality of the industry. But this is what they do. If you are looking for the newest, fastest, cutting edge .. "toys" heh ... look Otoy.
