Stay where I am or join HF

I am using a separate account to stay anonymous.

Anyway, here is a little bit of general background: I have been working since graduation for a unitranche/mezzanine fund with a separate mandate for leveraged loans in Europe. I have been doing very well here and am looking to be the youngest one ever promoted from A2A. That said, I know that our fundraising is struggling a little bit and it will be a major problem in a few years. I also don't like my team and how they approach investments (we are essentially a glorified IB). So I am looking elsewhere.
I was approached about an opportunity by a startup hedge fund which focuses on credit opportunities (anything from high yield to stressed/distressed) and private debt. My question is, how do I decide if it is for me?

Pro:
-Team with very strong, diversified backgrounds
-Got some serious seed capital from well recognized LPs
-Small team and chance to grow as they are growing rapidly

Con:
-Only recently launched

What questions should I be asking myself and how do I make a decision if this is for me?
