Startups are not for everyone. First off, a venture-scaled business must grow or it will die. Sometimes this is a necessary evil when it comes to decision making and I noticed coworkers kicking & flailing along the way who just couldn't cope with the fact that certain cute ideas had no realistic path to scale. From my experience, Reflex actually leans towards being a non-typical startup work environment - for a company of it's size it is highly structured from the top-down, which might slightly bug you are a 'go fast & break things' type of person (they are already past this stage). I would guess there is a sweet spot to working here right now; people who have experienced a post-series A-B environment would likely have the least culture shock.
