Personally I don't care if the product is web embeds or some other kind of tech. It seems to be good to make good-looking presentations and bad at making bullet-points and tables I've been sharing Seth's Godin "Really Bad Powerpoint" http://www.sethgodin.com/freeprize/reallybad-1.pdf for nearly a decade now (it's been around since 2001, but I was a consultant back then. Tables and bullet points put food on my table) and I'm still hoping someone will help the rest of the world understand. Google Slides didn't achieve that (quite the opposite actually if you've ever seen some Slides presentations) Prezi is definitely progress, but most people just import powerpoint presentations so it doesn't really work.
Conclusion: I won't judge Bunkr on features or tech, but on what presentations it actually yields.
(full disclosure: I don't know anyone in the Bunkr team personally, but I'm part of the same accelerator as them)
