Translation and notes
A readable adaptation of the article's core ideas, with the original source clearly credited.
A co-founder relationship should be treated as an operating decision, not a vibe check. Early startups often fail for ordinary reasons: goals diverge, work rhythms conflict, and unspoken expectations turn into resentment under pressure.
The YC questionnaire is useful because it forces the hard questions early: why each person wants the company, who owns what, where the team works, when everyone goes full-time, and what happens when decisions are hard. That is not bureaucracy. It is a way to make hidden assumptions visible before they become expensive.
The practical test is work, not talk. A short trial project, reference calls, and repeated time together tell you more than polished answers. If the collaboration does not feel stable in small conditions, it will not improve when the company gets louder.
What matters is not whether every answer is perfect on day one. What matters is whether the founders can surface disagreement early, make explicit tradeoffs, and keep revisiting the operating rules as the company changes.
Selected advice from the article
- Answer the questions separately before comparing notes.
- Lock roles, CEO, equity, location, and work rhythm before committing full-time.
- Set a clear trigger for quitting other work, whether that is funding, a customer, or elapsed time.
Operating takeaways
- Alignment is about explicit tradeoffs, not chemistry alone.
- Money, location, and schedule are operating choices, not side topics.
- Use a trial project and reference calls to test the relationship in real conditions.
- If conflict handling is vague, treat that as a real risk signal.
