The lead lifecycle is the process your leads go through in your
sales funnel: from their first engagement with your business to them becoming a paying customer. Instead of focusing on the sales process itself, the lead lifecycle focuses on how the lead moves through that process. It's ideal for customer-first companies.
Depending on a variety of factors, including your product or service, the lead lifecycle can be fast or slow. If it's more expensive, as
B2B sales tend to be, then you're likely looking at a longer lifecycle.
But you can't assume that one hard and fast rule will apply to all leads. Each lead has a different need and expectation, and this will affect the speed at which they go through the lifecycle. Someone might be ready to buy at a first interaction because they have a pressing need, while someone else may be in the process of months of nurturing and checking in. Still, some lifecycles in more static industries can take years.
What doesn't change are the general stages of the lifecycle.
