Made the jump from enterprise AE to associate PM two years ago. People asked me constantly how I did it and I kept giving vague answers because honestly I was still figuring it out. Now that I've been doing the PM job for a while I can be more direct.
What actually worked:
The customer obsession angle is real. I had 200 real customer conversations in my head. I could walk into any product review and say "three enterprise accounts told me this exact thing last quarter" and that carries weight. PMs without sales background often have to manufacture that by reading support tickets.
Positioning the switch: I didn't pitch myself as "a salesperson who wants to do something different." I pitched as "a revenue-focused operator who wants to work upstream of the problems I kept running into." That's a different frame and it landed better.
What was a trap:
APM programs. I applied to a bunch expecting my sales background to stand out. It didn't. Those programs optimize for CS/MBA with product thinking signals, and a 6-year AE with no technical markers gets filtered early. The better path was targeting Series B/C companies where a specific domain meant more than a clean pedigree.
Expecting immediate parity on comp. I took a $30k cut. Planned for it. Still stung.
