Yubo Could Be the Next Big Social Media App

French startup Yubo is the biggest social media app you have never heard of — unless you are a teen. With a focus on young people under 25, the company has managed to attract 40 million users. A fraction of them hang out every day in live-streaming rooms, meet new people and spend money for more features.

That is right, the company isn’t betting on ads. You can pay to unlock items or subscribe to the app. Yubo  expects to generate $20 million in revenue this year — that’s twice as much revenue than it generated in 2019.

Fashion brands should engage more proactively around sustainability on social media

Rather than using aggregated statistics and sentiment analysis, the research team used a qualitative approach to drill down into all the tweets posted around the two case studies, and divided them into key topics, positions, purpose and arguments, in order to determine how users engaged in the debate around sustainability and ethics in fashion.

They found that the two main ethics and sustainability issues raised by social media users were environmental concerns, in the first case study; and labor conditions in the supply chain, in the second. Analysis revealed that only a small proportion of tweets were explicitly critical and that those that were, were actually prompting a relatively sophisticated debate that fashion brands may benefit from engaging meaningfully with.
