Fluency, the Digital Advertising Operating System (OS) designed to scale paid media operations across all major channels, has announced the closing of a $40 million Series A funding round led by Integrity Growth Partners (IGP). Founded in 2017, Fluency consolidates the entire digital advertising workflow—spanning planning, execution, optimization, and measurement—into a unified platform. This enables agencies and brands to automate workflows and harness AI-powered insights across both walled gardens and the open web, achieving levels of efficiency and scale previously difficult to attain. The investment will support Fluency’s expansion into new markets, accelerate product innovation, and strengthen its AI-driven capabilities. By integrating data and tools from platforms like Google Ads, Meta, TikTok, Amazon, and programmatic ad exchanges, Fluency allows teams to manage cross-channel campaigns from a single interface, reducing manual work and improving performance. The company has gained traction among mid-to-large-sized agencies and enterprise brands looking to streamline their digital advertising operations amid increasing complexity and rising media costs. With the new capital, Fluency plans to enhance its machine learning models, expand its team, and deepen integrations with key ad platforms and data partners. Fluency’s platform is built to help marketing teams move faster, make data-driven decisions, and scale campaigns with greater precision. As the digital advertising landscape continues to fragment, the demand for unified, intelligent operating systems is growing—positioning Fluency as a key player in the next generation of performance marketing technology.
