Three paths:

1. Start applying for new roles at new firms and asking for more.

2. Ask your manager what you need to do at work to move up to the next level of compensation and responsibility (if they don't have a good answer for this it's a warning sign).

3. Start your own side business (either consulting or selling a product).

I agree with each of these three options, but probably not all three at once. Given the original question, probably 80% focus on number one and 20% number two.

Of course, iteration as necessary
