What Simile does
Simile is an AI-based human behavior simulation company founded in 2021 by Stanford researchers who originated the generative agents research field. The company builds digital twins of real people — "generative agents" — from structured interview data, allowing enterprises to simulate how target populations would respond to product launches, pricing changes, marketing campaigns, and other decisions before committing capital.
The core platform is a proprietary foundation model trained on 2.9 million responses from more than 400,000 participants across 200+ behavioral scenarios, combined with a multi-agent architecture that allows thousands of simulated personas to interact and respond to stimuli. Simile has also built what it describes as the first AI confidence model for predicting simulation accuracy, with disclosed validation showing outputs within 85% of human self-retest accuracy. Customers include Fortune 100 enterprises such as CVS Health, Wealthfront, Itaú, Suntory, Deloitte, Gallup, and Garnett Station Partners, with deployments spanning the United States, Brazil, Japan, the United Kingdom, Australia, Thailand, and Mexico.
Simile operates an enterprise SaaS business with quote-based contract pricing and direct enterprise field sales, targeting Fortune 100 buyers. The company reached commercial launch in February 2026 and reported 5x revenue growth in the following five months. It raised a $200 million Series B at a $2 billion post-money valuation in July 2026 and employs 50+ people globally. Strategic investors include CVS Health Ventures, and Simile maintains a research partnership with Gallup to embed its technology alongside traditional survey workflows.

Simile product offering
Product offeringCore offering
Simile provides a SaaS AI simulation platform that builds populations from real people through interviews and behavioral data, then trains AI models to simulate human behavior at scale. The platform enables enterprises to simulate product launches, pricing changes, campaigns, and market interactions before committing capital, with a first-of-its-kind confidence model that tags every result with a predicted accuracy level. Enterprises can also bring their own data (loyalty, balance histories, telemetry) to train custom models.
Product overview
Simile is a unified AI simulation platform that enables enterprises to simulate human behavior at scale for business-critical decision-making. The core offering is a SaaS simulation platform built on a proprietary foundation model for human behavior, combined with a first-of-its-kind AI confidence model that predicts simulation accuracy. The platform generates AI agents (digital twins) grounded in real human interview data and enhanced with behavioral and transactional data, enabling organizations to simulate product launches, pricing changes, campaigns, and market interactions before committing capital. Enterprises can also bring their own data (loyalty, balance histories, telemetry) to train custom models. The platform supports individual agent simulation, journey simulation over time, and multi-agent market simulations where customers, competitors, partners, and policies interact.

Simile competitors and assessment
Company assessmentDirect peers
- Remesh: AI-augmented market research and employee insights platform serving Fortune 500 customers; overlaps with Simile in the AI-mediated consumer research category.
- Listen Labs: AI-driven market research platform that automates qualitative and quantitative consumer research; competing head-to-head with Simile on the 'shrink research timelines' enterprise value proposition.
- Outset: AI-moderated survey research platform using generative agents to conduct qualitative interviews at scale; very similar enterprise customer segment and value proposition to Simile.
- Synthetic Users: AI-generated synthetic research participants for product and UX research; targets similar enterprise use cases (concept testing, customer insights) using persona simulation built on real data.
- Sapia.ai: AI chat-based interview platform using foundation models to automate candidate and consumer interviews; comparable AI-first approach to interview-grounded data collection.
Broad incumbents
- NielsenIQ: Global market research incumbent providing consumer insights to Fortune 100 CPG and retail customers; represents the budget pool Simile is potentially displacing with its simulation platform.
- Kantar: Established consumer research and insights firm serving global brands; legacy competitor that Simile's enterprise customers may substitute or augment with AI simulation.
- Palantir: Enterprise AI platform serving Fortune 100 with simulation, decision-support, and analytics capabilities at scale; comparable enterprise sales motion and customer overlap (CVS Health, banks), though broader in scope.
Others
- Scale AI: AI data infrastructure provider offering human-in-the-loop data labeling and evaluation services; adjacent infrastructure layer that supports foundation model training similar to Simile's validation pipeline.
Emerging players
- Hume AI: Builds foundation models for human emotional and behavioral expression (voice, expression); adjacent technology stack targeting enterprise insights use cases overlapping with Simile's behavioral simulation.
