Even the most promising concept, substantial venture capital backing from prominent investors, and a roster of well-connected angel supporters cannot guarantee success. Yupp.ai is shutting down less than a year after its launch, as announced by co-founders Pankaj Gupta and Gilad Mishne on Tuesday.

The company provided a crowdsourced service for selecting AI models. It enabled users to freely test and compare outputs from a library of 800 models, including leading offerings from OpenAI, Google, and Anthropic. For each prompt, Yupp would present multiple responses—whether text or images—and users would provide feedback on which models performed best and why.

The goal was to compile anonymized data on real user needs, which AI developers would then purchase. Yupp reported attracting 1.3 million users and gathering millions of preferences monthly, even featuring a model leaderboard. The startup also secured a few AI labs as paying customers.

However, the founders stated that "we didn’t reach a strong enough product-market fit" to continue, partly because AI models have advanced so rapidly in recent months. While labs do pay for feedback, the prevailing approach—pioneered by firms like Scale AI and Mercor—involves hiring specialized experts, such as PhDs, to integrate directly into reinforcement learning processes.

Furthermore, the industry's focus is shifting toward a future where AI is built for and used by other AIs. Model developers may seek some consumer input now, but they are primarily preparing for an era dominated by autonomous agents rather than human users.

"The AI model capability landscape has changed dramatically in the last year alone and will continue to change quickly," wrote Gupta, Yupp.ai's CEO, in a post on X regarding the shutdown. "The future is not just models but agentic systems."

Yupp.ai secured a $33 million seed round in 2024, led by a16z crypto's Chris Dixon—a notably large seed investment at the time. The company also raised funds from over 45 angel and small investors, including notable figures like Google DeepMind chief scientist Jeff Dean, Twitter co-founder Biz Stone, Pinterest co-founder Evan Sharp, and Perplexity CEO Aravind Srinivas.

Gupta mentioned that some Yupp employees are moving to a "well-known" AI company, while others are seeking new opportunities.
