I helped close a 9 figure raise … got nada. Is my company taking advantage of me?

No they don’t. You are an employee and get paid a salary. You might get a pay rise later.

More responsibility, more work means success. You will get your rewards eventually.

why would you expect to get raise when that money raised belongs to startup expenses??? If i'm an angel, I don't want my investment to be used for employee bonus.

You were rewarded with more responsibility. If money is your main driver, you should have communicated this earlier. Perhaps being money driven doesn't fir their culture?

If you are a top notch employee and help with key business that should be reflected in the equity that you get in the startup. That's the proper way to align interests, the company succeeds, you succeed.

If you feel that the equity package you have doesn't reflect that I would raise that issue with management.

Good luck!
