Bass diffusion curve

The Bass diffusion curve is a mathematical model that describes the adoption of new products and technologies. It was developed by Frank Bass in 1969.

The model shows that the adoption of a new product follows an S-shaped curve. It starts slowly, as only a few innovators adopt the product. Then, as more people adopt the product and spread the word, the adoption rate accelerates. Finally, as the market becomes saturated, the adoption rate slows down.

The Bass diffusion curve is a useful tool for understanding and forecasting the adoption of new products. It can also be used to identify the different stages of the adoption process, from innovators to laggards.

This is relevant to the virality stage of a startup, as it provides a model for how a product can spread through a market.
