909c

909c is a French social media agency that architects and executes brand communication strategies by leveraging the APIs of various social networks. The firm was founded in 2009 by Yann Guégan and Yannick Pons. Guégan, a journalist by training with experience at publications like Libération and Rue89, brought a deep understanding of digital content and community engagement, having transitioned to web-based journalism in 2007. This background in editorial innovation and user interaction shaped the agency's data-driven and performance-oriented approach.

The company's business model is centered on providing a comprehensive suite of digital and social campaign services. This includes strategic consulting, the design and development of social applications, brand content creation, and community management. Furthermore, 909c handles media buying as well as the analysis of statistical data to refine and measure campaign effectiveness. This end-to-end service portfolio caters to a diverse clientele that includes both major corporations and advertising agencies. The client roster features prominent names such as Accorhotels, Carrefour, Orange, Dior, and Citroën, alongside agency partners like Havas and DDB.

A significant milestone for 909c was the development of its own proprietary tool, Over-Graph. This social marketing platform was offered as a free-access tool designed to manage multiple social media channels simultaneously, demonstrating the agency's technical capabilities and commitment to providing practical solutions to the market. In March 2013, the Japanese advertising giant Dentsu completed its acquisition of the Aegis Group. Subsequently, in 2014, Aegis Media and Dentsu Network were rebranded as the Dentsu Aegis Network. While the specific date is not publicly available, 909c was acquired and integrated into this global network, operating under the Isobar brand, which is Dentsu's digital marketing agency.
