Seriously, look at their website: https://www.island.io/ There is not even a SINGLE image of the browser itself, it's just 3D renders, there is no way to test it. At least BREX, Slack and the others are product you can see, it's something that you can know it exists. Even in the use cases for the browser they don't show anything about the browser itself.
This is REALLY disappointing for any entrepreneur working on a REAL product and receiving NO from every single investor they talk to.
I mean: i, a nobody, has a solid product, has paying clients. But because i am not friend of a VC or somebody else i need to listen that my product is not good enough, that it will never scale, that i don't have the right revenue to justify an investment. You can see my product, you can test it if you want. But then a guy comes with something that doesn't even have a proper website and is valuated a billion dollars out of the gate.
It's just sad to see what the startup ecosystem has become.
