SIEN

What SIEN does

SIEN SA is a Paris-headquartered, privately-held technology company founded in 2006-2007 that develops a portfolio of consumer-facing mobile and desktop applications alongside a B2B SaaS monetization platform. The company operates from three offices in Paris (France), Bucharest (Romania), and London (United Kingdom), and employs 51-100 people, of whom nearly two-thirds have development backgrounds. SIEN's product portfolio comprises six core offerings: two Android homescreen replacement apps (UR 3D Launcher and UR Mood Launcher), a fully customizable Chromium-based browser (1st Browser), a web gaming aggregator (Yappyz), a virtual pet game (My Cute Buddy), and IVIDENCE, a SaaS platform that helps web and email publishers intelligently optimize and monetize display and email advertising inventory through real-time user profile adaptation.

The company's technology foundation centers on Chromium-based browser development combined with proprietary algorithms that analyze millions of anonymous data points monthly to drive personalization. Its consumer apps monetize primarily through advertising and virtual goods (custom wallpapers, icon packs, themes, gaming content), while the IVIDENCE platform generates SaaS revenue by enabling publishers to adapt ad delivery to user profiles in real time. SIEN reports more than 493,502 downloads per day across its consumer products, indicating substantial distribution reach.

SIEN's revenue model is dual-pronged: an advertising-supported consumer application business with virtual-goods transactions on the B2C side, and a SaaS offering targeting web and email publishers on the B2B side. The company raised approximately $7.75 million in disclosed venture funding between 2006 and 2008 from AGORANOV, 360 Capital, and I-Source Gestion, and transitioned into B2B services through its May 2015 acquisition of IVIDENCE. Recognitions include TechCrunch Europe Top 100 startups, European Techtour Top 25 (2009), Microsoft BizSpark program membership, and Best Innov 2007 from Capital IT.
