I hate all the comments here so adding my own take (I have a different perspective than many here as I sell software - I don't build it).

A feature or features is what your software does literally. A company is an ideology around what your company's vision is.

Docusign's features were about e-signing documents. Their vision was/is "to accelerate business and simplify life for companies and people around the world."

Sounds like fluff. But it's actually pretty important to have a vision because it gives your customers/investors/employees direction on the types of products that you can build. Docusign could build and monetize any product that accelerates business or simplifies life. They have e-sign now - but later they can have other stuff. People who purchase Docusign hope/expect they'll roll new features around their company vision and is why they choose Docusign vs. others.
