Pros
Great people at the individual contributor level. Unique industry with a whole lot of potential (if someone gets it right). Snacks are always stocked. Great benefits: 5% 401k match, fitness reimbursement, commuter subsidy, 100% medical, dental, and vision, etc.
Cons
Ultimately the overall health of an organization is a reflection of the executive team and works it way down. The executive staff was a carousel of people between 2015-2016. Someone with a "C" in their title was fired about every 2 months, no exaggeration. It was interesting a sign of a much larger problem internally. Prosper was not set up to succeed. It was odd that they always talked about transparency but weren't transparent. The company scaled way too fast due to seemingly to greed. Prosper Day was fun though. Roll out a rebrand, share a couple TV commercials, have an executive fashion show sporting the new colors, and then a few days later tell the company that we're on a hiring freeze and that the business is hurting. Hire as many people as possible, rent a bunch of space in SF & Phx, build a new office in Salt Lake, and lay off 28% of the company and sublease the extra space. I fear that tougher times are ahead. That said, there are far worse places to work. If you just need a job and are hurting to get back to work, this may be a good fit.
