  "account": "Mirror Particle is developing a world model to predict human behavior. The San Francisco-based startup, founded by Abhivyakti Ahuja, her co-founders Will Song and Thomson Yen, and backed by angel investors, aims to build a foundation model that simulates human behavior and changes over time. Unlike large language models (LLMs), Mirror Particle doesn't rely on fine-tuning the models with limited data. Instead, it uses a combination of data sources such as client customer data, current events, pop culture, and social media to model a demographic segment as a system that evolves. Mirror Particle focuses on \"revealed behavior\" – what people actually do, rather than self-reported survey answers. The prediction engine provides customers with the \"why\" behind current or future behavior, helping brands make smarter decisions. The startup's long-term vision is to become the \"general layer for anticipating human behavior\" and move from broader population-level analyses to individual-level insights. Mirror Particle is competing in TechCrunch's Startup Battlefield, a startup competition, and the winner will be decided by a slate of VC judges on October 15.",
  "summary": "Mirror Particle will launch at TechCrunch Disrupt Startup Battlefield with a world model built from scratch to predict human behavior, arguing LLM roleplay falls short for market research and brand strategy.",
