The Nantes (France) based startup Lengow just launched its new service called TagCapsule. Lengow was founded in 2009 and offers online shops an interface that helps them to optimize, control and centralize the publication of product catalogues. The new service TagCapsule enables online-shops to use a single tag to encapsulate all analytics- and partner-tags into a single one. The new service, wich was launched in beta this week, is free for all current Lengow users. According to the young company there are already 300 e-merchants out of 3 countries that are using Lengow’s service. Lengow is financially backed by Kima Ventures.
