Business Development in Finance

So, I'm currently working as an Account executive at a SaaS company (3 years out of undergrad, 2 years as an AE). Currently making around $180k all in working around 25-30 hours a week. Staying in this path I should be able to move to another tech company, land an enterprise role and increase my comp to $300k-ish over the next couple years. After that the goal would be to go into management, eventually ideally becoming a VP of sales. I'm in the Bay Area so there are a lot of AE roles hiring at all times and the path seems pretty clear.

I have been reached out to a few times by recruiters for roles in boutique and mid-market PE firms. I got an offer from a boutique growth equity firm last year but declined because it was a significant pay cut ($80k base plus sourcing bonuses). Most of these roles are "deal sourcing" and business development in portfolio operations type roles (One specifically at a pretty well known VC/Growth Equity firm).

My question is, should I "switch careers" and do this? The role I'm currently interviewing for is bus dev in "portfolio operations" at a name brand firm but its a pay cut (around 140k all in) and I also can't find any information online on what this career path looks like? Where do you go from here? How much money can you make in this career? What are the hours like in PE/VC bus dev? Is it a respected role? 

Basically, I've always wanted to work in this industry because I find it interesting, but I don't know what a career here looks like in terms of comp and progression. Ideally I want to make as much money as possible per hours of work I put in. Will this be better than SaaS sales for that?
