WHAT WOULD YOU DO?

Lets just call this a 'what if' game.

The situation:

You have a business with lots of potential which promises many 'digits' growth. Suddenly a giant multinational says "we want you to work with us for 3 years because you are developing something that we want but you need to be one of us". We might even buy you!!

The Q:
What would you say to the giant?
