Leads are the start of every sales journey. The level of interest leads show or do not show distinguishes the type of lead. A cold lead is a person or organization who has never heard of your company's products or services. A cold lead can be nurtured if it has the qualities your customers typically have. A hot lead is a person or organization with a strong interest in your business. Hot leads typically understand the problem they need to solve and how your product or service can help them solve it.
