It is very rewarding in the sense you can get multiple startups worth of advice. I've worked for two startups in the past several years, one with a CEO who had never sold (or scaled) a tech company. The other had a founding team with several acquisitions between them.

I heard many times "well something like this happened at XYZ company and this is what we did and it didn't or (or did work". Granted many problems are new with each venture, they all had a vast set of knowledge and startup experiences between them. I learned a lot by working with them and hearing their reasoning behind decisions.

Their network was also very, very strong as a result of having been around the block. This made for easy access to almost any company we needed to speak with.

It is also neat (and I learned the most) to be able to communicate on a very high level in all discussions. It was a totally different experience from the prior startup where I had to preface everything with a breakdown of the basics first (this is what SEO is and how it words).
