Fluency secures $40M Series A to expand AI-driven ad automation platform

Fluency has raised $40 million in a Series A funding round as it looks to accelerate the development of artificial intelligence tools designed to automate digital advertising campaigns across channels. The round was led and fully funded by Integrity Growth Partners, according to company statement.

Founded in 2017 and based in Burlington, Vermont, Fluency operates what it calls a digital advertising operating system, a centralized platform that allows brands and agencies to manage creative development, campaign execution and reporting from a single interface. The company says its platform currently supports nearly $3 billion in annual media spend and more than 250,000 campaigns each month across search, social and programmatic channels.

The funding comes as advertisers face increasing operational complexity driven by fragmented media platforms, rising data volumes and pressure to manage campaigns more efficiently. Fluency’s system relies heavily on automation through customizable rules, known internally as “blueprints,” which allow advertisers to adjust budgets, targeting and creative based on predefined conditions, while still retaining the option for manual intervention.

A growing focus for the company is agentic AI. Fluency has been developing retrieval-augmented generation tools that allow users to query performance data in natural language, analyze contextual factors such as weather or demand shifts, and automatically apply recommended changes back into live campaigns. According to company executives, the technology was initially built in response to client demand for reducing manual optimization work.

Fluency plans to use the new capital to deepen its AI and engineering capabilities, expand integrations with publishers and technology partners, and increase hiring across product, engineering and AI roles. The company expects its workforce to grow significantly over the next year as it pushes further into automation-led campaign management.

While Fluency has been profitable since 2020, management said the business has historically reinvested cash flow into product development and growth. The Series A funding is intended to accelerate that strategy as agencies and brands gradually adopt more fully automated advertising workflows.

Integrity Growth Partners will take a board seat as part of the deal. Fluency will continue to operate independently under its founding leadership team.
