# Proud Engine launches MarCoP, a headless SaaS platform for marketing AI

Proud Engine has launched MarCoP, a headless software as a service platform designed to support the use of artificial intelligence in marketing. The service began operations on October 26, 2026. The company, which previously focused on advertising agency services, introduced this tool as part of its expansion into the AI and digital transformation sectors. MarCoP aims to maximize the value of marketers by connecting data and business context to generative AI systems.

The platform addresses specific challenges that companies face when integrating AI into their practical workflows. These challenges include the management of authentication credentials for advertising platforms and the need to control token consumption when linking data to AI models. MarCoP allows organizations to isolate sensitive information within their own Google Workspace environments. It aggregates and processes marketing data that is scattered across multiple external services. This data is then connected to AI systems along with the company's specific business context, such as decision-making metrics and operational rules.

MarCoP provides three primary functions to facilitate this process. The first function is the centralized management of authentication credentials for web services, including advertising platforms and communication tools. The platform issues its own credentials for AI systems, allowing them to call external service APIs within defined rules without requiring direct access to individual service credentials. The second function is a lightweight data warehouse that manages various marketing data. This system organizes data formats and metrics that differ by advertising medium, enabling companies to manage data efficiently even without specialized database engineers. The third function involves providing resources to generative AI, including processed data and prompts. These resources incorporate business context, such as metric definitions and judgment criteria, to ensure stable output results and reduce excessive token consumption.

The service adopts a headless model, which means that after initial setup, marketers can call MarCoP functions from the generative AI tools they already use. There is no need to open a dedicated management screen for the service. This design allows for integration without significantly changing existing work styles, thereby reducing the burden on marketers. At the time of launch, MarCoP is compatible with only a limited number of generative AI systems. The company plans to update the platform to support major generative AI systems by the end of March 2027.

Proud Engine also plans to expand the service's capabilities to include creative production and to offer the service in a form integrated with AI models. The company's goal is to create a marketing environment where marketers and AI generate value together. Tasks that can be delegated to AI will be handled by the technology, while judgment, strategic planning, and co-creation with customers will remain the responsibility of marketers. This approach aims to achieve an appropriate division of roles that leverages the strengths of both parties.
