I found a unicorn - help.

Let's say you come up with a brilliant unicorn startup business idea and plot twist - you're an employee in IBD.

If you create your business plan and investor pres. using some work resources, does the bank have any legal claim to remuneration or to the business after you quit and hit it big?

If you create materials without company resources while still an employee, does the bank have any legal claim to remuneration or to the business after you quit and hit it big?

FINRA states you have to declare outside business activities - what's timing on this? Is it safe to do so immediately prior to incorporation? Do you do this as soon as you begin drawing up a business plan?

Thanks.
