Paul Graham's tips on dealing with investors

We looked into one of Paul Graham's classic essays on fundraising for some insights. In this essay, he gave the following 5 tips (among others) on how to deal with investors.
Here goes:

1. If it isn't yes, it is a no: Investors often lead startups on with vague enthusiasm, so treat them as a “no” until they give you a firm, unequivocal “yes.” Many investors delay decisions or avoid direct rejection, or to maintain optionality. To protect yourself from wasting time or being misled, confirm every agreement in writing and remain skeptical until the money is committed. Don't stop fundraising or take options off the table until the money you raised is secured.

2. Leave the valuation to the end: If an investor starts pushing you on valuation too soon, steer the conversation back to whether they’re genuinely interested in investing. Avoid being dragged into price discussions before they’ve committed to your startup. Focus first on getting a “yes” from the investor—valuation can be worked out later if they’re excited about your company.

3. Meet investors only if you're actively fundraising: When you’re not actively fundraising, avoid meeting with investors who just want to “chat.” Investors always have an agenda, even if they say they’re only looking to get to know you. If you’re not prepared to engage in fundraising, politely decline these meetings and promise to reconnect when you’re ready to raise funds.

4. Keep your cool to turn a "no" into a future yes: Even when investors say no, keep the relationship warm and professional. An investor who passes on you now might reconsider in the future, especially if your startup progresses well. View rejection as the beginning of a potential long-term relationship, not the end. Investors often come back when startups show traction or success in later stages.

5. Know where you stand with investors: Always leave investor meetings with a clear understanding of the next steps. Ask investors what they need to make a decision, how long it will take, and what their internal process is. If they are vague or avoid committing to a next step, take it as a warning sign. Investors who are serious will communicate their process clearly and openly.
