I founded a company about a year ago and will do $80k on sales this month and $100k next month. I hired a marketing consultant in April who has done an amazing job and really helped get us to where we are.<p>I pay him and I am still a volunteer.<p>He is asking to be made co-founder and get 30% equity.<p>I have no idea what to do but an acquaintance who is a VC said I should first get a 409a from a lawyer to determine the value of the company then back into an equity split.<p>Is that premature? Should I just email something like you get X% and co-founder title vesting over four years with a one year cliff?<p>Bonus question is how much equity do you think he should get?
