Andreessen Horowitz, Sequoia, NFX and Y combinator are all top rated, famous Venture Capital Funds. They invest in what they expect to be fast-growing, hugely profitable companies. They also write some good blogs!

VCs frequently look for and preach about the concept of "Product Market Fit." They suggest that any company needs it to succeed. In short, it's whether people want what you're selling.

It's worth reading on the topic from a variety of sources, so that you can understand and know what to look for in whether you have a business and a product that will succeed with customers.
