WhoFundsWho is a browser extension available on Chrome that provides users with instant access to information about the funding sources behind the experts, politicians, think tanks, and other organizations they come across while browsing the web. Developed by kmswinkels, this free extension aims to bring transparency to the information we consume by revealing the biases and interests of these entities.

The extension works by highlighting the names of organizations and people for whom it has funding information in its database. By simply clicking on or hovering over the highlighted name, users can open a popup that displays relevant funding information. But WhoFundsWho goes beyond financial details, it also provides insights into other aspects such as past affiliations, organizational relationships, partnerships, and network memberships.

In terms of customization, WhoFundsWho offers several options in its user menu. Users can choose to turn the extension on or off, decide whether the popup opens with a click or hover, and opt for a quick summary or full information display. Additionally, users can select whether to highlight all instances of a name or just the first two, and even choose specific categories of organizations and people to focus on.

For those concerned about compatibility, WhoFundsWho runs on all webpages by default, but users can also specify websites where they want the extension to run or not. The extension also allows users to select their preferred highlight and text colors.
