I am one of two founders on a pre-launch startup, we hold the full equity in the company, equally. The prototype is built and we are currently in beta testing with roughly 40 users. We have had someone helping us out voluntarily over the last couple of months with marketing and content and we are keen to have them on board full time in December. We are discussing an equity agreement right now, which is fair for us both. This will most likely be for 6% total, with 4% at the end of 2015 (subject to vesting), 6% by the end of 2016. If they leave earlier the shares will be deferred. Does this sound sensible? is this too little/too much? Do you have any advice on this? We are really keen to keep them on board, but also want to be sensible.
