You’re being very disingenuous.
You don’t have a business. You have an idea. There’s nothing to steal.
You’ve done less than 10% of the work, not 90%.
As for product/design feedback: the name is terrible. I want a FULL sip, not half of one.
And the ‘thin’ lip of the cup, as rendered, looks incredibly thick. Since it’s double-walled, and ceramic, this is likely to be a huge manufacturing problem. Bodum already makes double-walled glasses for coffee. Why are you better?
