Need some help framing an experience for my resume – appreciate any thoughts on title & dates! (Context: currently looking for full-time Product roles at early/mid-stage companies)

Timeline:
- Joined cofounders as an advisor in Sep '22, spent ~10hrs/mo giving feedback on mockups & product vision
- Scaled up to "full-time" (no salary) in July '23 to help with GTM: led sales & discovery calls, support & onboarding, and synthesized feedback into a product roadmap
- Scaled back down to ~5hrs/mo in Jan'24 as the founders retooled and figured out what was next

I've been calling this "Product Advisor (Sep22-Jan24)" but think I could maybe say "Founding Product Manager (July23-Jan24)"?
