Mobile marketing firm Upstream has been named as one of the 25 fastest-growing digital companies in Europe in the GP Bullhound Media Momentum Awards 2011.

The awards recognise the achievement of Europe’s digital businesses and celebrate innovation in the sector. They recognise those companies that have seen the most significant growth over a three-year period. Previous companies recognised by the awards include Spotify and Net-a-Porter.

Upstream started out in 2001, launching some of the first global mobile marketing campaigns for blue-chip brands such as Coca-Cola, T-Mobile, Vodafone and Nestlé. The company says its ability to deliver highly effective solutions that generate value from any customer base has made it the preferred mobile marketing partner for some of the largest companies across the globe including Vodafone, Telefónica, MTN, Unilever and Shell.

Upstream’s Marketing Communications Suite (MCS) technology platform increases customer responsiveness by as much as 400 per cent by using optimised communication; message contextualisation and unique customer engagement mechanics and formats through its marketing gamification engine. Upstream clients also benefit from the platform’s ability to analyse millions of interactions on a real-time basis to deliver key insights into campaigns as they roll-out.
