If someone proposed a deal with me to control 60% of my company and I had the remaining 40% is that a good deal considering my company not bringing in enough revenue? Included in the deal are resources to media equipment and business training to help me become a stronger salesmen.
Do you want a job instead of to be an owner?
No way! Read "How To Get Rich" by the dear departed Felix Dennis, who did not have to sell a single copy of his book because he was already bloody rich. (Compare/contrast against so many other "gurus".) You'll read that he says not to give one single % of equity away.
Without 51%, you are no longer in control. If you want someone else telling you what you can and can't do with the company you created...if you want a job or worse because they can limit you to being a silent partner or consultant now that you are just a minority partner with a few rights...go ahead.
You can do this some other way.
