About MCAP Acquisition Corp

MCAP Acquisition Corp. is a U.S.-listed special purpose acquisition company (SPAC) that traded on the NASDAQ under the ticker MACQ. Rather than operating as a conventional industrial or service business, MCAP was created to raise public-market capital and complete a merger, stock exchange, asset acquisition, or similar business combination with an operating target. The company was sponsored by an affiliate of Monroe Capital LLC, a Chicago-based private credit and asset management platform, which positioned MCAP within the broader ecosystem of sponsor-backed capital formation. SEC disclosures show that MCAP raised roughly $316 million in its March 2021 IPO and later completed a business combination with AdTheorent in December 2021. For investors, this means the company’s relevance is largely tied to its SPAC history and the post-transaction structure rather than to a standalone operating model. In practical terms, MCAP served as the listing vehicle for AdTheorent, a U.S. digital advertising and machine-learning company. AdTheorent’s core proposition is centered on programmatic advertising powered by advanced data science, predictive modeling, and privacy-forward execution. Its main products and services focus on audience activation, performance media buying, campaign optimization, and cross-channel measurement for advertisers and agencies. The platform is designed to help brands identify high-value consumer segments and deliver measurable outcomes in an environment where privacy regulation and the deprecation of third-party cookies increase demand for first-party data strategies and algorithmic targeting. From a competitive standpoint, the business associated with MCAP operated in a crowded adtech market against large platform owners, independent DSPs, and data-driven marketing technology vendors. Its differentiation lay in the use of machine learning to optimize campaigns and reduce reliance on sensitive or third-party identifiers, while aiming to preserve performance and accountability. Geographically, the business was primarily concentrated in North America, with commercial activity in the United States and Canada and a more limited international footprint. Key recent developments include the announcement in April 2024 and the completion in June 2024 of Cadent’s acquisition of AdTheorent, a transaction that materially changed the public-market story linked to the former MCAP vehicle. For French-, Belgian-, and Swiss-based investors, MACQ should therefore be viewed as a U.S. NASDAQ SPAC history connected to the adtech and communications segment, with its market identity shaped by the AdTheorent merger and subsequent corporate actions in the United States.
