Multiple values in a single mysql field

I'm building a mysql database to store companies information. In one of the fields i need to store multiple values like the name of the founders.

I'm aware that won't be a good choice but it would avoid to create another table just to store a few names.

I'm concerning to the question regarding retrieving and querying the values on that specific field.

I really appreciate your input so that i can make a good choice even that require more code lines.

TIA
