Investors often overlook what happens after demo day; many good companies will raise additional funds six to twelve months later. Maintain a relationship with the founder to be helpful, as this can lead to future investment opportunities.

YC's demo day provides a unique opportunity to connect with a large number of investors, which can significantly accelerate funding efforts for startups.

If you're attending demo day without prior research, be prepared to act quickly, as other investors may have already done their homework.

Having extra funding helps founders approach fundraising with confidence, making it easier to negotiate and plan without being influenced by fear.

YC companies often receive numerous inbound offers from investors, contrasting with the common experience of founders who typically have to reach out to investors themselves.
