Fiksu was a prominent mobile marketing technology company that specialized in providing data-driven solutions for mobile app user acquisition, engagement, and retargeting. Its platform offered advanced tools for programmatic media buying, campaign optimization, and precise audience targeting, empowering app marketers to achieve their growth objectives. Founded in 2008 (as Fluent Mobile, rebranding to Fiksu in 2011), the company played a significant role in the mobile advertising ecosystem. Fiksu was acquired by Noosphere Ventures in 2016, and subsequently, its demand-side platform (DSP) assets were acquired by RTB House in 2017. Fiksu's technology and expertise have since been integrated into RTB House's offerings.
Served as the central command for Fiksu's global operations, including product development, engineering, sales, marketing, client services, and administrative functions for its mobile marketing platform.
The headquarters was likely a modern, open-plan office space designed to foster collaboration and innovation, characteristic of tech companies in Boston's vibrant Seaport District or South End, where it was located.
Fiksu was known for a dynamic, fast-paced, and data-centric work culture. It emphasized innovation, agility, and a strong focus on delivering measurable results for its clients in the rapidly evolving mobile advertising landscape.
The Boston headquarters was crucial as it was the birthplace and operational core of Fiksu, a key contributor to the early growth and development of the mobile app marketing industry. It stood as a notable entity within Boston's thriving tech ecosystem.
Prior to its acquisitions, Fiksu maintained a significant global presence to support its international clientele. Key functions such as sales, client management, technical support, and market expansion for its mobile app marketing platform were distributed across strategically located offices in North America (Boston, San Francisco, Northampton MA), Europe (London, Helsinki), and Asia (Seoul, Singapore, Tokyo).
