Pros
Product is aimed at solving ambitious challenge with big TAM. In Mountain View you could be offered Silicon Valley level comp and perks (but don't get excited too fast: a proper discount is embedded in the low quality of experience and poor job security). Some people find it cool to have blue chip companies as customers.
Cons
Product-market fit is not found, which is a bit overdue. Company has lost times more customers than it has retained. Long implementation time and feedback loop. With product being sold in 3 year deals, value to the client is realized only many months into the contract, if at all. High management turnover. Chances are, you'll get to work for a person with small tenure who is still figuring stuff out, not trusted by top management, looks for her/his own next gig elsewhere and has no incentive for investing in you. There is no basis for expecting a consistent culture. Personality and skill set of the CEO. Nader is charismatic and probably personally responsible for all revenue company has. Without relationships he built with customers there is probably no company. However, resulting confidence in his own judgement could be getting in the way of hearing other people and making best decisions for the company.
