Composite

Composite is an AI company building browser automation tools for professional work. Its core product is an intelligent autopilot delivered as a Chrome extension, which predicts and executes tasks directly in a user's existing browser. Rather than routing work through hosted browser instances, the system runs AI locally, an architecture the company says yields instant response times and avoids migration or IT overhead.

The technical work centres on action prediction models that operate in real time, inferring what a user will do next from page context and prior interactions. The stated aim is to remove repetitive digital labour so that professionals can concentrate on higher-value tasks. The relevant domains include machine learning, real-time inference, on-device execution and Chrome extension development.

Founded in 2025 and based in San Francisco, Composite emerged from stealth the same year and raised $5.6m in seed funding. Its investors include Nat Friedman, Daniel Gross, Menlo Ventures, Anthropic's Anthology Fund and SVAngel. The founding team has ties to institutions including Stanford University. The company operates across professional and knowledge work, enterprise software and productivity tools.
