Vantaggi
Decent benefits. Seems like most salaries are competitive. Great co-founders who are present daily. Could MAYBE be a good stepping stone job for an extremely high performer - but don't plan to stay long.
Svantaggi
It seems the company is being positioned for sale, which means they don't care about working you to the bone. Easily expect to work 50-60 hours a week. Emails go out explicitly telling employees they must be available and checking email on weekends, holidays, and days off. The software is not competitive... this was a "first-to-market" kind of product, and many competitors are getting up to speed. I don't see how the company will be around in 5 years. Someone fired every 6-8 weeks. Sometimes 10% of the company at a time.
