The most hyped investments on demo day are often not the best; the crowd's perception can be misleading.

During demo day, founders often have a list of interested investors, allowing them to choose who to engage with. This gives founders more control over their fundraising process, which is crucial since many dislike fundraising.

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

You can do your homework on YC companies before demo day by reading about them on blogs and product launch sites.

In fundraising, it's important to do your homework on potential investors, including their past investments and interests, to position yourself advantageously.

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.

When talking to investors, research their recent deals to gauge their openness and fit for your startup.

In negotiations, you can delay your response to avoid making hasty decisions; don't feel pressured to match the investor's expertise.

If you don't have deal flow, you'll end up taking the first opportunity that comes your way, which can lead to poor investment decisions.
