Build a browser extension that demos your product on prospect websites to make cold outreach tangible and prove ease of integration
Instead of describing your product abstractly in cold emails, build a lightweight tool (browser extension, bookmarklet, or overlay) that instantly shows your product working on the prospect's own website. This transforms cold outreach from theoretical pitch to concrete demonstration, and simultaneously proves your product is easy to integrate. The prospect sees their own product improved, not a generic demo.
When to use
When selling developer tools, widgets, or embeddable products to other SaaS companies where integration is a key concern
Don't do this
Sending generic demo links or screenshots that don't show the prospect's own product. Also: spending days customizing each demo instead of building a reusable tool.
