About Scope3

Scope3 is building the future of advertising for an AI-driven world. Global brands rely on us to grow safely and sustainably, and by combining sustainability, media quality, brand safety, and fraud detection, we deliver measurably better performance and control for advertisers.

Scope3 has established clear industry leadership through rapid innovation. In October 2024, we secured a $25M financing led by GV, Venrock, and Craft Ventures to expand into AI and introduced the first methodology for measuring AI‑related carbon emissions in advertising. In November 2024, the acquisition of Adloox created a comprehensive multi‑signal verification platform. In 2025, we launched the Scope3 Agentic Advertising Platform—the industry's first platform for designing and deploying AI agents to dynamically optimize media investments.

Scope3 is not retrofitting AI into a decades‑old infrastructure. We’ve reimagined the media buying process from the ground up with AI at its core. This approach enables brands and their partners to train and deploy specialized agents that make superior decisions informed by rich, source‑level media intelligence, wherever digital media is sold.

Scope3 is a fully remote and largely asynchronous organization, enabling global collaboration and flexibility, with concentrations in New York and Europe. We partner with 150+ leading brands and agencies, alongside over 100 publishers and platforms across North America, EMEA, and APAC. At this time, we have employees in Canada, Australia, UK, France, Germany, Netherlands and the United States.

Reporting to the CFO, the Controller will serve as a strategic finance leader, driving the financial integrity and operational foundation behind a company redefining how global advertising works in the AI era. This leader will be responsible for all accounting operations, financial reporting, compliance, and treasury management, ensuring Scope3 scales with precision as our agentic advertising platform experiences rapid growth. The ideal candidate brings deep expertise in marketplace or platform business models with experience managing complex revenue recognition, multi‑currency operations, and international subsidiary compliance.

For this position, we are looking to hire in the US, specifically located within Eastern Standard Time to optimize for global collaboration.
