I currently know of software engineers that have been working there for 1 and 2 years. Individually they are each making between 50k and 60k a year.

Don't need quite as much revenue when employees are cheaper.

I remember Riverside (pretty close to Redlands) in the 1990s and it was dirt cheap, even during the era of the $1 gallon of gasoline. $100k in pay + benefits stretches far there, especially once you factor in the higher revenue per employee in other nations (43 years + 350k orgs using their software sounds like a multinational).

How much is that company you started making per employee?
