Software Development Paris, Ile de France 51–200 employees Founded 2015 Privately Held

Yubo operates a social discovery app centered on direct connection over algorithmic feeds, running millions of active users on a data-intensive infrastructure stack (Kafka, Kafka Streams, MongoDB, Elasticsearch, dbt, Airflow). The project list—A/B experimentation, growth experiments, backend foundations, design system scaling—reveals a platform optimizing for retention and conversion at scale. Pain points around data pipeline throughput, interaction tracking reliability, and churn reduction map directly to these initiatives, signaling heavy investment in analytics-driven product iteration.
