How to convince someone to join your startup

Executive overview

Recruiting co-founders and early employees starts with one thing: your own conviction. If you have doubts about your idea, others will sense them.

The harder the road, the more your belief matters. Teams that are only loosely committed quit when things get rough. Teams that are deeply convinced push through pivots, funding gaps, and team loss.

Convincing yourself is the prerequisite to convincing anyone else.

Signs of genuine conviction

• The idea occupies your thoughts and disrupts your sleep — a strong signal
• You find working on it feels like entertainment, not effort
• Positive external feedback pulls you further in, not just validates you
• Cynicism or low energy toward an idea is a signal to move on

Why excitement beats commercial logic

• Ambitious and incremental ideas are roughly equally hard to execute
• If difficulty is constant, always pursue the idea you care most about
• Commercially "safer" ideas won't carry you through the rough patches
• At YC, teams secretly unconvinced of their idea consistently quit under pressure

Building conviction over time

• Conviction can grow — work on the idea on the side and track your own engagement
• If time on it feels like fun, that is data
• User recognition and positive feedback create momentum that deepens commitment
• Treat early side-project traction as signal to take the idea more seriously
