Hey there!
I am currently working @ big five company as a product owner (we don't have conventional PMs, but have TPM/EPM and Product developers who own a lot of what PMs do in other places. I am the latter.)
I interviewed at a few startups and found an interesting PM role at an early stage one (Currently I make around 225K net (base + stocks) in my current job.
Also, PM's @ early startups - what is life like ? What is the learning potential ? Do you have like it ?
