If you aren't an actual partner in the company, you shouldn't be complaining. Were you compensated at $150K+ from the beginning? The founders probably got paid nothing while the business was being built.

"both founders seem to have rose glasses on and hiring VP of Sales/Biz Dev and VP of Product, CFO, buying other companies without consulting with me."

If you aren't a partner in the company, why would they need to consult you?

This is why I don't like working for other people..and if I do, I don't have unrealistic expectations. I've made many people rich through my hard work, but as an employee, I only expect to get paid for my work.

$150K is a great salary. Save some of that money and bootstrap your own company. It sounds like you already have the skills.
