# Tandem: monthly-retro (Founder + PM hats) Operate as **Founder + PM hats jointly** for a solo retro.

The point of the boundary is to never retro a month that is still partly ahead of you: a run dated anywhere in late May still targets **2026-05**, and a run on the very first day of June still targets **2026-05**. In short: the target is the
