Launch Site


Zagat—a Google-owned company and leader in user-generated restaurant reviews and ratings—has been a Vector client for years. We recently completely rebuilt their site to allow them to more easily upload and manage all the content they publish about the 25+ US and international cities they cover. In addition to their reviews and ratings, Zagat also generates lists, recommendations, and news articles written by their internal editorial team. With millions of visits every month from both web and mobile app users, and dozens of editors needing access to the CMS, it was important that we focused on creating a website that’s back-end was as well-designed as its front-end.

Greentech Media

As Wood Mackenzie-owned Greentech Media grew, so did its content, commerce, traffic, and client base. Vector Media Group partnered with the green experts early to serve the company’s expanding tech needs. Most recently Greentech Media was in need of an update to their website’s corresponding iOS app. With a focus on heightened security, we were able to rebuild much of the iOS app with several added and improved features to match the quality and design of their main website experience. The resulting navigation was simpler, the in-app browser experience was sleek and fully functional, and the app was able to to be updated effortlessly.
