Start-up or PE

depends how risk averse you are and the startup's potential. no one is going to be able to answer this with zero information on the startup's funding, your comp, etc

How much equity are you getting? Since you're recruiting for PE as well, I don't think it would be too hard for you to model what your stake would be worth at various exit values (keeping in mind you will be diluted by fundraising along the way)

In general the PE comp will have a much higher floor, and likely a higher ceiling unless you've joined a future unicorn. Keep in mind there's only like 10-20 companies per year that exit at a >$1B valuation so more likely than not this startup ain't it

To echo everyone else, it is up to your tolerance for risk.

Kid in the analyst class above mine was debating the same thing last year. Ended up picking the start-up over a more traditional PE offer. He received some amazing stock options, etc. in his first 9 months, but COVID hit, he got laid-off, and the start-up is on the brink of bankruptcy. Doubt many PE associates are in a similar position at the moment, but then again, this is just one isolated story. I'm sure others have had way better experiences.

Bear in mind, it is the startup. As long as you can take high risk, it is potentially the most effective place to make huge cash. It is like investing in one junk bond without having a portfolio. If you have enough money to live through 3+ years at least, startup with high potential is a way to go.

Chances of you landing a meaningful PE gig vs a meaningful startup job is not even comparable. If you have the confidence go the startup route. the pe firms will beg for you down the road but make sur you focus on the financing side of things. and don't pick a shitty startup.
