Composite, a newly founded AI startup, has secured $5.6 million in seed funding from venture vehicle NFDG (helmed by Nat Friedman and Daniel Gross) to further develop its innovative cross-browser agent tool. Unlike many “AI browsers” that force users into proprietary environments, Composite works as an extension in existing browsers (Chrome, Edge, etc.) to help automate professionals’ repetitive tasks across web apps. The tool can draft emails, aggregate data from different sites, update project trackers, and more — all executed locally on one’s machine without server-side dependency. Composite was co-founded by Yang Fan Yun (formerly at Uber) and Charlie Deane, and it already claims early traction across users in large tech firms. The funding also includes participation from Menlo Ventures and Anthropic‘s Anthology Fund.

Key Takeaways
– Composite adopts a “meet users where they already work” strategy by embedding agentic automation into existing browsers instead of forcing users to migrate to a new AI-centric browser.
– The reliance on local execution (tasks run on the user’s device) addresses many privacy and security concerns associated with cloud-based agent tools.
– The $5.6 million seed funding round led by NFDG, with support from Menlo Ventures and Anthropic’s fund, demonstrates investor confidence in the viability of cross-browser agent workflows.
In-Depth
In the fast-evolving space of AI agents and “smart browsers,” Composite hopes to carve out a niche by targeting professionals burdened by repetitive browser tasks. While many recent launches in this realm—such as Perplexity‘s Comet or OpenAI‘s agent experiments—are pitched toward consumer use cases (booking flights, summarizing web pages, casual research), Composite is explicitly aiming at the “grunt work” people in marketing, recruitment, security, analytics, and operations do every day. The company sees an opening in automating tasks that lie inside the browser but span multiple web apps: dragging data from dashboards, filling templates, jumping across SaaS portals, and generating drafts of emails or reports.
The technical approach is noteworthy. Composite operates as a browser extension rather than as an entirely new browser. That means users don’t have to abandon their established workflows or lose access to their extensions, bookmarks, logins, and institutional tools. When a user is already logged into multiple services, Composite can piggyback off those sessions to execute actions. The AI agent suggests automations based on observed patterns: for example, it might notice that every week a user consolidates data from Jira, Google Sheets, and internal dashboards, then build a script to do it automatically. Users invoke actions via a lightweight overlay (keyboard shortcut) rather than a heavy UI.
Another strategic decision is to run tasks locally on the user’s machine rather than in the cloud. This sidesteps many privacy, latency, and enterprise compliance concerns. Composite also layers in safety features like website blocklists, confirmation prompts, and the ability to disable automation — giving users and IT more control. Because it doesn’t rely on cloud connectors or third-party APIs, it avoids needing extensive integrations.
Investor backing reflects belief in the model. The $5.6 million seed round led by Nat Friedman and Daniel Gross’s NFDG, along with participation from Menlo and Anthropic’s Anthology Fund, gives Composite runway to expand its engineering, refine its models, and scale adoption. The startup already claims early traction at prominent tech firms. For professionals drowning in tabs, cross-app transfers, and repetitive data tasks, Composite offers a vision of a browser that not only displays your work but helps run it.
