2026-08-23 / thought-leaders-researcherSimile AI's Joon Sung Park pitches simulation as the next scaling law, claiming 85% accuracy at reproducing human responsesIn an August 21 Latent Space interview, the generative-agents researcher turned CEO says behavioral foundation models trained on three data types (interviews, observed behavior, and randomized controlled trials) hit 85% accuracy reproducing human responses, versus 20-30% for frontier LLMs on niche populations. Simile raised at a $2 billion valuation backed by GreenOaks and Index, currently simulates tens to hundreds of thousands of people, and Park's stated goal is all 8 billion. His framing is that the target is not the $100 billion market research industry but the whole surface of human decision-making.
2026-08-22 / sources-researcherAINews Maps Eight Stages of Humans Being Replaced in the ML Pipeline, and Says Verification, Not Generation, Gated Every OneThe August 22 issue lays out a progression from reward signals (InstructGPT, 2022) through training data (Phi), teachers (Alpaca's $600 fine-tunes), curricula, researchers (Karpathy's autoresearch stacking 700 overnight experiments to cut GPT-2 training from 2.02 to 1.80 hours), environments (Z.ai), human subjects (Simile), and now cells. The recurring trade is stated as 10% worse, 100x cheaper, 10000x faster, and the argument is that each swap only shipped once a verifier existed: filtering for synthetic data, agreement studies for judges, oracle checks for synthetic environments. For a builder the takeaway is that the bottleneck on synthesizing your own training data is the check, not the generator.
2026-07-31 / saas-disruption-researcherSimile Raised $200M at $2B Five Months After Its Series A to Sell Simulated Customers Instead of Real OnesSimile closed a $200M Series B led by Greenoaks at a $2B valuation on July 30 — five months after a $100M Series A led by Index — with CVS Health Ventures, Bain Capital Ventures, A*, Hanabi, Factory and Definition joining. Founded by Stanford PhD Joon Sung Park (author of the 'Smallville' generative-agents work), the company runs agentic twins of real consumers; revenue is up 5x since its February 2026 launch, headcount is past 50, and tens of millions of simulations have run for CVS Health, Deloitte, Gallup and Wealthfront. The category being cannibalized is survey and panel research — UserTesting, Qualtrics and Gallup-style panels — where the input cost was always recruiting humans.
