Build a Browser Extension That Lives Inside Your Users' Marketplace

Build a Browser Extension That Lives Inside Your Users' Marketplace is a product-led growth tactic for getting your first users: Rather than pulling freelancers to a separate site, they shipped a Chrome extension that overlays on Upwork itself, intercepting users at the exact moment they evaluate jobs and write proposals.

It's a strong fit for Agencies / services and Marketplaces teams, and works especially well for tools that augment an existing platform. As a product-led growth play, plan for high effort and expect results to arrive at a steady pace, all grounded in 1 linked primary source.
