Ask HN: Career crossroads

HN,

I'm faced with my first major career move, and I need some unbiased advice.

I have two options:

1) be a leader (but non-exec) in a very sexy (very early) B2B startup run by high-caliber people in an industry I love, working with people who share my philosophy and principles. Decent equity (but high likelihood of dilution because it's quite a capital-intensive business), solid pay raise and significant responsibility increase relative to my current position.

2) be an exec (make two jumps in title), nearly double my salary, and get a solid amount of equity at a non-sexy but already established company that is a former leader in its industry but has grown more slowly lately bc of poor execution the last few years. I have worked with the recently-hired (new) exec team in the past and I trust them, but our philosophies are different, and I know I'll bear additional stress (I know I'll be stressed anywhere) related to our deep-seated disagreements. All that said, because they trust me, I'll have instant credibility on the exec team and with their (very well-known) investors.

What's your advice?
