Generative agents. Foundation models. Some of the core ideas shaping modern AI trace back to Joon Sung Park, Percy Liang, and Michael Bernstein. Now they’re building Simile - digital twins of people as enterprise infrastructure for decision-making. Proud to lead their $100M

It’s not every day you come across a genuinely new, seemingly sci-fi idea like Simile's: to simulate human behavior by partnering deeply with real people to build high-fidelity models of how they live and make decisions. It’s even rarer to find a team that’s so uniquely suited to

Today we're launching Simile, the simulation company. What happens when AI can help you foresee how real people will respond to your decisions, your ideas, your products, and your policies?

Introducing Simile. Simulating human behavior is one of the most consequential and technically difficult problems of our time. We raised $100M from Index, Hanabi, A* BCV, Andrej Karpathy Fei-Fei Li Adam D'Angelo Guillermo Rauch scott belsky among others.

We’re thrilled to lead Simile's $100M Series A! By building digital twins of real people grounded in real interviews and real data, we believe they’re creating the foundational infrastructure for decision-making in an AI-native world.

While most AI tries to fix humans Simile is building AI that understands them. They build digital twins that capture someone’s worldview, then simulate how customers, employees or entire populations will actually respond to change. Born out of Stanford generative agent

Congrats on the launch Simile ! (and I am excited to be involved as a small angel.) Simile is working on a really interesting, imo under-explored dimension of LLMs. Usually, the LLMs you talk to have a single, specific, crafted personality. But in principle, the native,

AI that predicts earnings call questions is in the works. Simile CEO Joon Sung Park says his startup correctly forecast eight out of 10 analyst questions on a recent simulated call. The company has raised $100 million to scale its human-behavior prediction tools

Simile Congrats Simile team! Simulating behaviors is an amazing opportunity for AI to help our work. Massive research opportunities with immediate application!

ok this is actually a sick 404 page lol
