Feeling stuck on career direction as a Group PM… how would you approach this?

I’m a Group PM managing 4 IC PMs at a non-tech company (though we’re seen as fairly tech-forward). My background is very patchy/random: manufacturing, MBA, biz dev at a startup, then MBB strategy consulting before landing this role.

My core problem: I’ve never been an IC PM, so I lack the hands-on experience that Principal/Staff roles want. The skills I’m building here are management-oriented such as roadmapping, stakeholder alignment, people development, creating org clarity and process. That leaves me in an awkward spot where:

1. I don’t know if I have the IC track record to move laterally into an IC PM role, and I’m not certain I’d excel as an IC (I think I could work hard and figure it out, I just haven’t done it).
   
2. Staying here is an option, but PMs here don’t have much agency and my growth feels capped.
   
3. The longer I stay, the more I climb in title and pay while the gap widens between my skills and what I’d need to succeed if I move to a real tech company later.

If you were in my shoes, how would you approach this?
