How Replika grows

Replika comes up in one interview as an example of an app with huge organic growth, alongside Solid Starts. The guest used it to argue that organic-only apps eventually saturate their niche, and pointed to a full Japanese localization that did not work and to early hiring of machine-learning people.

• Replika made a big bet on Japan, with a Japanese-speaking team member fully localizing and adapting the app, and the guest said it did not work at all and was harder than expected.Replika

• Replika hired machine-learning people before the field was popular, which the guest credited for the product's quality; no numbers were given.Solid Starts
