Brilliant post — very informative + clearly written. > What goes unsaid, is that only the actual partners in the fund get any carry, associates just get a comfortable salary and the prospects of becoming a partner (at another firm obviously) "(at another firm obviously)" — I've heard this in other discussions about VC careers too. Why is it the case?
Any of the first three options will help sell LPs and founders on your new fund by bringing along some brand name credibility. It’s a harder sell when you are promoting from within, especially as associates do not have experience raising money from LPs.
Another reason: Venture firm partnerships are inherently political environments and perception matters. It is akin to why grad students are discouraged from becoming professors at the same school they got their PhD from. It’s hard to escape from the shadow of your mentor and find your own footing.
There a few other reasons that promotions are rare, but they do happen. A16Z used to have a rule where no one internally would be promoted to be a GP because they only wanted to have former operators be partners (they have now since changed that policy https://a16z.com/2018/07/17/connie-chan/)
