Composite gets backing from NFDG for its cross-browser agent tool (techcrunch.com)

Composite, a startup founded this year by ex-Uber PM Yang Fan Yun and proxy entrepreneur Charlie Deane, raised $5.6M in seed funding led by Nat Friedman and Daniel Gross’s NFDG with participation from Menlo Ventures and Anthropic’s Anthology Fund. The company launched a Mac-focused, extension-based “cross‑browser” agent that automates professional web workflows without forcing users into a single AI browser. By operating inside browsers where users are already logged in, Composite performs atomic actions (clicks, typing, form fills) across sites to handle tasks like triaging Jira backlogs, leaving comments, marking duplicates, drafting personalized outreach, creating vulnerability tickets, and aggregating marketing reports. Technically and strategically, Composite’s key differentiators are its extension-first, connector-free approach, local task execution, admin controls and site‑blacklisting for workplace safety, plus pattern-based task suggestions and planned scheduling features. That positioning targets professional use cases that multi-site agents and single‑browser AI tools aren’t optimized for, but it also puts Composite into a crowded, early‑stage field—competing with OpenAI/Perplexity browser agents, Notion’s contextual workflows, and desktop/contextual startups like Highlight. Investors cite usability for nontechnical professionals as a strength; the company will need to demonstrate robust, long‑term efficiency and security to win enterprise adoption.
