Be very careful joining here - Anonymous employee Next Big Thing Employee Review

First of all, be aware that the percentage you get in the beginning, which is already not high, will be further diluted through investments. In the end you have, in my opinion, close to nothing left. Second: Everything can change quickly without any explanation. Your project, your manager, people leave, people get promoted after 2 months etc. etc. And it is all very badly communicated, sometimes without any justification or via chat-tools instead of personally. I would be very careful leaving your job for this. For me it was totally not worth it.
