Virality (startup stage)

Virality is the third stage of the Lean Analytics framework. The goal of this stage is to get your customers to spread the word about your product.

This is a quantitative stage, focused on measuring the viral coefficient and the viral cycle time. It's about building a product that is so good that customers can't help but tell their friends about it.

The spread of a viral product often follows a predictable pattern, which can be modeled by the Bass diffusion curve.

The key metrics in this stage include:

• Viral coefficient: The number of new customers that each existing customer brings in.
• Viral cycle time: The time it takes for a customer to invite a new customer.

The goal of the virality stage is to build a self-sustaining growth engine for your business. A high viral coefficient can dramatically reduce your customer acquisition costs and accelerate your growth.
