Yupp Shuts Down After Raising $33M Seed Round

Yupp, an AI-focused evaluation platform that gamified human feedback for large language models, is shutting down. The company had raised a $33 million seed round led by a16z crypto and built a platform where users compared side-by-side responses from hundreds of AI models, provided preference feedback, and earned rewards. Despite reporting significant user activity and collecting large volumes of model preference data, the company said it did not reach strong enough product-market fit. Existing users were given time to access chat history, download data, or delete accounts before the service closed. This record is marked as a full company shutdown, with 50 employees affected and 100% of employees impacted.
