A go-to-market strategy that enables customers to discover, adopt, and purchase software in a self-service model without the assistance of a traditional sales representative or other human being.  Product-led growth models are widely adopted in the SaaS and cloud industry.   A freemium or free trial model is offered to new customers to provide them with hands-on access to the product.  Customers like the self-service model because it allows them to define their buyer experience rather than being forced into a vendor-defined sales process.  customer-specific SaaS companies benefit from product-led growth because it lowers new customer acquisition costs.
