About CloudX

CloudX is a technology company rebuilding the foundations of mobile advertising for the era of artificial intelligence. Founded in 2025 by Jim Payne and Dan Sack, the creators of MoPub and MAX, the firm aims to provide mobile publishers with advanced tools for intelligent monetization. Payne, who serves as CEO, has a long history in mobile advertising, having founded MoPub in 2010 to bring programmatic buying to mobile and later starting MAX in 2017 to create a unified auction system for publishers. This extensive experience in developing transformative advertising platforms informs CloudX's publisher-first approach.

The company's core offering is an AI-native, supply-side platform (SSP) that moves beyond legacy systems. Its infrastructure is built around a Trusted Execution Environment (TEE), a secure technology that underpins every auction to ensure verifiable transparency and data integrity. This allows for the use of AI agents to manage and optimize monetization in real-time, enabling publishers to automate complex tasks like segmenting audiences, setting dynamic price floors, and structuring custom auctions. CloudX provides its software development kit (SDK) for integration into publisher apps across various platforms, including Android, iOS, and Flutter. The system includes real-time analytics and full log access to give publishers transparent insights into their ad performance.

CloudX launched publicly in November 2025 after securing a $30 million Series A funding round. The round was led by Addition, with participation from DST Global, Terrain, and seed investors such as ENIAC, Javelin, and Breakpoint Capital. The capital is intended to scale product development and accelerate the adoption of its AI agent-driven architecture. At its launch, the company announced integrations with major ad platforms like Meta, Liftoff, and Magnite, with broader access planned for early 2026.
