AdMeIn is a creative validation and simulation platform with ad previews, built for teams working with digital advertising across display, video, and CTV. It helps ad operations, media buyers, publishers, and developers confidently test, inspect, and debug ad creatives before they go live. At its core, AdMeIn focuses on validating the most common (and problematic) creative formats used in modern ad tech, including VAST video tags, HTML5 display ads, JavaScript tags, and creative ZIP files. Users can upload or paste creatives and instantly receive structured feedback on technical compliance, rendering behavior, and potential delivery risks. This includes detecting malformed markup, broken assets, missing files, incorrect click handling, unsupported features, and common issues that cause ads to fail in real environments. Beyond static validation, AdMeIn simulates how ads behave in real-world scenarios. Video creatives can be previewed through VAST playback simulations, helping teams verify media files, tracking events, redirects, and wrapper behavior. HTML and ZIP creatives can be rendered in a safe preview environment, allowing users to visually inspect layouts, animations, and interactions while ensuring click logic and assets are correctly implemented. AdMeIn is designed to support modern workflows - whether you’re QA-ing creatives at scale, troubleshooting third-party tags, onboarding new partners, or validating ads against publisher and exchange requirements. Clear reporting, fast feedback, and a format-agnostic approach make it easy to catch issues early, reduce back-and-forth with partners, and prevent costly campaign delays.
