The venture studio playbook, open-sourced
Every venture studio runs roughly the same playbook. It is not a secret; it is a gate. Here is the whole thing, published, with the StartupKit tool that replaces each session.
Week 1 — Problem and positioning
A studio partner would workshop your problem statement until an investor could repeat it back. You can do the same in an afternoon with a structured pass: one customer, one pain, one measurable consequence. The positioning framework on StartupKit is the canonical version of this exercise.
