I'm taking part in a startup where I'll be developing and maintaining the web site and my two other partners are handling the business aspects. I was brought into the startup at a later point, so I'm getting 10% equity and they're each getting 45%. When the company starts making money, the profits will be split equally three ways.
I was offered a stock purchase agreement that has a 1 year cliff for vesting, and then monthly vesting after that up to 4 years, but there's a clause that allows the company to terminate me without cause at any time and buy back any unvested stock. To me this is obviously a problem, but the partner that produced the agreement is telling me this is the standard agreement that investors will expect to see. My question is, what protections can I ask for that will still not scare away investors? I'm thinking earlier vesting and not being able to be fired without cause. Any advice would be appreciated, since I'm completely new to this.
