Lerna AI

Lerna’s vision is a mobile app ecosystem that can leverage granular user data, while preserving privacy. To get there, Lerna is building a novel solution (SDK & service) that helps mobile app developers improve their retention rates by categorize their users based on their churn probability and plan subsequent actions (e.g. push notification). Lerna is combining federated learning and cutting-edge privacy/security to allow for the training of ML models on rich user data, always on-device.
