Pros
Colleagues, especially below the senior management tier, are exceptional. Some of the most patient, skillful, kind, worthwhile people you'll ever work with -- and people who will wind up doing great things at other places in the future. A lot of reviews heavily criticize the CEO and I'm not sure that's entirely fair. Flatiron is a wholly-owned subsidiary of a global pharmaceutical corporation. Our "CEO" is basically a VP in disguise, with very little ability to influence the meager amount of the parent company's budget we receive. I don't think there's much our leadership could do, realistically, to change the company's course.
Cons
There's no way to sugarcoat it. Flatiron probably has a year, maybe two, of viable operation left. It's not entirely clear what's going to happen next, but there's no chance left of it being good. It operates massively in the red, can't raise, can't grow fast enough to close the gap in time, and is right in the crosshairs of its cash-strapped and beleaguered parent company. If you're here now, treasure every moment with your colleagues that you can while you quickly, but calmly, start moving towards the door. If you're considering coming here, reconsider. If you have no other good options, then you'll be rewarded by some really lovely colleagues and challenging, interesting work. But that could all change or go away at any time, and it appears that it may do so quite soon.
