According to co-founder and CEO Mark Maunder, Feedjit widgets reach over 150 million unique users on a monthly basis.

The startup has made a strong key hire, appointing RescueTime co-founder and former CEO Tony Wright as Head of Product.

Over the weekend, Feedjit also launched a totally new design for both the Feedjit.com website and the Live Traffic Feed, improving the ability to customize widgets and making for a generally faster experienced thanks to upgraded back-end systems.

Feedjit now lets site visitors appear in live traffic feed widgets in real-time, while linking directly to their respective Twitter and Facebook profile pages.

Feedjit quietly closed a seed round back in 2008, from a trio of angel investors made up of Naval Ravikant, Aydin Senkut (former senior manager at Google who now runs Felicis Ventures) and Georges Harik (former Director of Googlettes at Google).

Having raised less than half a million dollars, it’s pretty amazing for Feedjit to have grown up to become one one of the largest widget providers on the Web today.

The Feedjit traffic widget launched a month ago and is now claiming some fairly serious viral growth – 3 million impressions per week from the blogs that have added it. When installed on a blog, the widget shows people who enter and leave the site and, and where they are located. Neither the blog publisher nor visitors need to register for the service – the code just has to be on the site.

Feedjit offers two types of widgets. The first resembles MyBlogLog in that it shows recent visitors to the site. I’ve installed it at the end of the post. Tonight the company added customization features to let people set the size and color scheme of the widget via Ajax controls. “Arring Town,” shown below, is my favorite for obvious reasons.

The second widget, integrated at the top of the post, shows a map with the location of the last 100 visitors. Hover over any dot to get more information about a person.

This is an excellent widget and is much easier to use than MyBlogLog. If Feedjit can keep growing at this rate, though, perhaps an early exit is also in the cards for them. There’s only so much extra space on a site, though, and there are simply too many “must have” widgets. It’s all gotta end sometime.
