Our Work

A small collection of our projects

Ghost in the Shell

Universal gave us creative freedom with the marketing assets that we were delivered. Using Greensock animations we coded banners for desktop, and specifically mobile MRAID in app placements. The star quality and high level animation lead to good conversion rates.

Assassin's Creed

We have had the pleasure of working with Ubisoft to promote games including Ghost Recon and now Assassin’s Creed for their newest release. Ubisoft in Germany approached us to create a eye catching Canvas ad within the Facebook platform. The canvas ad achieved high engagement and excellent reach across gamers.

Voegele Reisen

Voegele Reisen in Switzerland have been working with NMPi Zurich to generate more awareness and leads online. NMPi requested that we support their client to design and code dynamic banners that could be managed through google studio with elements changed in real time.

Two sets of creatives were designed and developed by AGCS ahead of schedule. The results of the campaign were excellent. Voegele Reisen received a number of travel bookings on their site with an outstanding return on their media and creative investment.
