AI browsers like Perplexity’s Comet, Opera’s Neon, and The Browser Company’s Dia promise to help users complete tasks more efficiently—but they’re limited to their own ecosystems. Composite, a new startup founded by Yang Fan Yun (ex-Uber PM) and Charlie Deane, wants to change that by building an AI agent that works across any browser.
The company announced it has raised $5.6 million in seed funding, led by Nat Friedman and Daniel Gross’ NFDG, with support from Menlo Ventures and Anthropic’s Anthology Fund.
AI Agent Built for Workflows
Composite is designed for professionals who spend hours in the browser. The tool currently runs on Mac and Windows through a simple extension and can perform actions across multiple web apps. Example use cases include:
- Engineers: manage Jira backlogs, resolve duplicate bugs, leave comments on critical issues.
- Recruiters: find candidate profiles and draft personalized emails.
- Marketers: pull analytics data from multiple sources into quick reports.
- Security teams: turn alerts into vulnerability tickets.
Unlike consumer-focused AI agents, Composite is built for workflow automation without technical complexity. “We’re ideal for professionals who want automation without coding,” Yun explained. “Composite excels at atomic actions like clicking, typing, and navigating websites to get the job done.”
Privacy & Control for Teams
Because Composite works in the user’s existing browser sessions, it doesn’t need external connectors. Companies can also restrict which tools are allowed, block specific websites, and run tasks locally for greater security and privacy.
The tool already suggests tasks based on usage patterns, and upcoming features will include automatic task surfacing and recurring scheduling.
Competition & Outlook
The AI agent space is heating up, with players like OpenAI, Notion, Highlight, and others exploring different approaches. Still, investors believe Composite’s cross-browser, professional-first focus gives it an edge.
“Composite handles multiple sites and workflows very well,” said Matt Kraning, partner at Menlo Ventures. “It’s intuitive, not overly technical, and designed for professionals who manage many tasks across functions.”
With fresh funding and growing demand for productivity-focused AI, Composite is positioning itself as a strong contender in the emerging AI workplace automation market.
