Thanks for adding your thoughts, Sebastian. Yes, you're absolutely correct about SAFE notes.

However, as you point out, eventually, the note converts into equity.

Certainly you can have two types of equity if you are a "Strong Founder"., but those types of deals are much more difficult in the tough funding environment we face today.

And different voting rights will only get you so far. If your investors are unhappy with you, they will cause you all sorts of trouble including forcing you out. Just ask ex Uber CEO Travis Kalanick.

And yes, negotiate the best terms you can. And yes, the terms will vary.

But, make no mistake about it, the second you take outside you have effectively given up control of your startup.
