Category Standard

Place Exchange is a legitimate, market-leading Supply-Side Platform (SSP) for programmatic Out-of-Home (OOH) advertising, with verifiable annual revenue estimated at ~$20M and a team of ~80 employees. The company was acquired by Broadsign in late 2025. Despite the project's high real-world utility and massive verifiable traction (partnerships with The Trade Desk, Google, etc.), the submission itself ('ShadowStorm') was of exceptionally poor quality, providing vague claims ('most people have used my product') and missing data ('marketcap: null'). The score reflects the project's high verified status, heavily penalized for the low quality of the submission evidence.
