Some things are a bit confusing, and may need more clarity in order to help reason about the situation: 1) The advisor, who has "little shares", is also the "CEO-sales manager"? Does this mean that the advisor is the CEO, or that he's the one responsible for bringing in the $100K (in sales + services revenue)? 2) You are currently the CTO, mainly focused on a lot of the R&D, prototyping and product development. It seems that the advisor is proposing that a new position be created ("Product Engineering Manager"), yet you make no mention of whether you still retain the CTO title. If you're upset that you'll be delegating the important product development responsibilities to somebody else, yet you still keep your title, then perhaps this isn't a bad thing as you would hopefully be ramping up a larger technical team for you to (learn to?) manage. 3) It's not a problem to express doubts about a decision. What's more important is that your founders and advisor sit down and discuss the issues one by one. If your advisor is angry with you, he should try to explain why. 4) What is the equity agreement that you have? I can't help but feel that this would have an impact on the discussions, and will be an important factor in deciding whether to part ways (hopefully with vested equity still intact). 5) "Fight for the position I think I must work in" - is that as the PEM, or as CTO?
