You need a big market for your startup, which typically means a billion-dollar market, or a small but rapidly growing market.

When evaluating a startup idea, it's important to identify a significant problem that many people face, as well as to ensure that the problem is growing, urgent, and expensive to solve.

Startups should target markets that are either starting to experience or are about to experience exponential growth, as this is crucial for long-term success.

The startup journey is inherently high-risk and requires a commitment to solving real problems, rather than just analyzing market potential.

Investors often overlook the potential of existing large markets, thinking they are too crowded, but if you can create a significantly better product, there's room for many winners.

To create a massively successful startup, you need to have a huge market and make something that a lot of people will pay for or that people will pay a lot for.

Startups should initially focus on narrow markets to gain momentum, but eventually need to identify and build towards infinite markets to achieve significant growth.

Successful companies often start with small markets and expand over time; going after a large market from the beginning usually indicates a lack of proper market definition.

Scaling your startup before achieving product-market fit can be dangerous; it's better to spend as little as possible while figuring out what your product should be. If you have product market fit, customers will actively seek your product, and even a basic version can solve a significant problem for them.
