Pros
They reel you in with a fancy office, free lunches, and a hope that there is focus on building an actual product. Unfortunately this is all for show. Upper management just wants to sell, sell, sell above everything. This is the case, even if that means disregarding the product's state, team and its progress.
Cons
Company and product goals change almost daily according to who they're talking to. There is no focus or time given towards building the product first, but there is an insistent need to keep trying to sell (a product that they don't yet have.) Promises are made to brands by management and marketing, resulting in intense pressure for the teams and eventually disappointing outcomes for everyone. The company bends to whoever and whatever they can get, forcing the team to back peddle and make major changes within extremely short deadlines. Basically there is no backbone at all for the product. Vixlet is less a tech startup, and more like a circus promising to provide random services (even if they have to lie about it.)
