Pros
The network really is excellent. I still refer to notes from mentor sessions that occurred years ago. At ERA, you'll actually learn tactics to build product and generate revenue. The team is invested in your success. I left ERA years ago and still consult with Jon and Murat whenever I'm considering a career move. I've worked for several ERA companies since leaving the ERA team. This is a pretty common occurrence for people in the ERA network. If you're willing to work hard, you will get a ton of ownership -- well beyond what you could get anywhere else, early in your career. You have to earn the team's trust, but once you do, you will be given responsibilities that would take you 10 additional years to earn anywhere else. ERA is a generalist investor, so you'll be exposed to a ton of different industries. To give a few examples, when I was there, I worked on investments in fintech, consumer internet, CPG, media/entertainment, and frontier medical diagnostics. There are very few investors with this level of breadth -- it will enable you to learn a ton. In my two years there, I probably saw 3000 startup pitches. We wound up investing in about 50 or so. The level of deal flow is quite high -- you'll get plenty of reps in for evaluating startups. If you're willing to work hard to succeed, this can be a career-defining opportunity.
Cons
ERA is a place to launch your career -- it is not a casual, informal, 9-5 job. To gain the trust of the founders you'll work with, you will be expected to perform. So if you're looking to mail it in, this is not the place for you An under-discussed part of venture: not all your companies will be winners. Most VCs will throw in the towel and cut them loose: ERA does not. ERA works as hard to help its struggling companies as it does it surging ones. This is not always fun! You'll have to roll up your sleeves to help companies that e.g. lack a CFO, and need to figure out how to turn 3 months of cash into 12. You'll learn a ton from doing this, but it won't always be fun in the moment
