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

As an investor, one of the worst things you can do is follow the crowd; the best investment decisions are often those that others overlook.

Investors often respond to ideas that are popular or trending, which can mislead founders into thinking they should follow the crowd rather than pursue their own insights.

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.

Many people jump on trends too early; for example, VR has potential, but it's not yet a high conviction bet for starting a company.

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

Coinbase faced immense challenges in raising money during demo day, highlighting how investors initially viewed the idea as unviable.

Many investors mistakenly follow trends set by others, like benchmark investments, without conducting their own due diligence, which can lead to poor investment decisions.

Investors often chase opportunities in startups, hoping to profit from future growth, which can lead to inflated valuations that may not be sustainable.
