What this teaches

Suster's most famous mental model: every founder-investor interaction is a dot, and investors gain conviction from the line those dots draw over time. Argues founders should meet investors months before raising and show progress against stated plans.

Why it matters

Reframes fundraising from a one-shot pitch into a relationship built on demonstrated execution.
