I have no idea what this phase is like
The Four Phases of a Partner/Co-founder Relationship
Carlos E. Espinal

Confirmed, this phase exists!

It is extremely fulfilling to bounce ideas and discuss the next adventures with your partner, from the quantum state of from one hand knowing them really well, and on the other hand having a certain personal disattachment from what they are working on to maybe contribute a bit more as an objective bystander.

Looking at you, Silver Keskkula & Balaji S. Srinivasan, and entire early #skypemafia. Thank you.
