Marginize is a Boston-based provider of software that creates a "social space" on any web page. Its core product is a browser plugin that augments every web page with a sidebar. The sidebar surfaces what the world is saying about a page on Twitter, Facebook and Buzz, and enables users to interact via comments and check-ins. The company has raised $1.3 million in venture capital, according to a filing with the Securities and Exchange Commission. Fifteen investors participated in the offering. The article was published by Massinvestor, Inc. Marginize provides a persistent right‑hand frame on webpages that displays user comments and tweets and lets people share the page they are viewing. The service also includes a Foursquare‑like check‑in component to show how often users visit a site. To combat empty pages it populates margins with tweets that link to the site, and to lower friction it offers an HTML‑rendered sidebar view that doesn't require a plugin. For persistent use across pages the company provides browser plugins for Chrome and Firefox, with Safari coming soon, and a bookmarklet alternative that works per page. Founder Ziad Sultan and the team emphasize solving chicken‑and‑egg and plugin‑barrier problems that hampered prior attempts in this space. The article does not report revenue or user metrics.
