To Get Started Free tier, no credit card, no time limit

Anyone who has worked in digital advertising knows the feeling. You spend hours building a set of HTML5 banner ads. You zip them up, upload them to the ad platform, and they come back rejected. Wrong click tag. File too large. Missing backup image. Unsupported script. Every platform has different rules and none of them tell you exactly what's wrong.

"We kept debugging the same errors over and over. There had to be a better way."

AD Exhibit started on a marketing agency request. A simple validator tool that would check their HTML5 banners before they ever touched an ad platform. Then we added preview links so we could share creatives with clients without emailing zip files back and forth. Then we added the optimizer — a one-click fixer for the most common errors. Then social media mockups for image, GIF and video ads.

What started as a script became a platform. We decided to open it up to anyone who makes ads for a living — freelancers, boutique agencies, in-house creative studios, trading desks. If you ship ad creatives, ADExhibit was built for you.

One platform.
Every step
of the workflow.

We mapped out every point where HTML5 banner ads and social media ad creatives slow teams down — and built a tool for each one.

How we got here

Early 2025

The problem gets loud enough

A european client requested an internal software after one too many HTML5 banner rejections and a client deadline missed over a broken click tag, we build them an internal validator. We decide to keep going.

Mid 2025

Preview links & campaign management

We add shareable preview links and a way to organise campaigns by client. Suddenly we're also solving the "can you send the latest banner sizes?" email chain. Teams start asking to try it.

Late 2025

Optimizer & social mockups launch

The one-click HTML5 optimizer ships — fixing click tags, metadata, file size, and custom exits automatically. Social media mockup previews follow for Instagram, Facebook, TikTok, Reddit and X.

2026

ADExhibit opens to the public
