I Made the Switch: Traditional PM to AI PM in 4 Months

I was a senior PM at a mid-size B2B SaaS company, managing a team of 8 engineers building workflow automation features. I had shipped 12 major features in 3 years, grown my product line's revenue by 35%, and felt like I had a solid handle on the job. Then my company started an AI initiative, and I realized I could not even follow the conversations in the planning meetings.

The gap was not just technical vocabulary. I did not understand why the ML team kept talking about "evals" instead of QA. I did not know why they could not give me a firm ship date. I did not understand why a feature that worked great in a demo fell apart with real customer data. It felt like being a first-year PM again, except everyone assumed I should already know this stuff because I had "senior" in my title.

I decided to make the transition deliberately rather than waiting for my company to figure it out for me. I gave myself 4 months. Here is what happened.
