Our story

The $1.6 billion problem
we're solving

Amazon discovered that a 1-second slower page load could cost them $1.6 billion in sales. Yet millions of websites run uncompressed, losing visitors every second.

The genesis

A simple question
sparked everything

"Why is this website so slow?" It was 2019, and we were debugging yet another sluggish site. The answer? No compression enabled, 2.3MB of uncompressed HTML was being served to every visitor.

What shocked us wasn't the problem itself—it was how hard it was to simply check if compression was working. Diving into dev tools, running curl commands, deciphering headers... There had to be a better way.

"Compression is the process of encoding information using fewer bits"
— Ilya Grigorik, Google

The Lightbulb Moment

After spending hours debugging a client's slow e-commerce site, we discovered it was serving 2.3MB of uncompressed content. Enabling GZIP reduced it to 400KB—an 83% improvement that transformed the user experience.

Going Public

We shared our tool with the developer community. The response was overwhelming—within weeks, we had thousands of users discovering that their "fast" websites were actually crawling due to missing compression.

"Every millisecond matters. When Amazon found that 100ms of latency cost them 1% in sales, we realized that compression isn't just a technical detail—it's a business imperative."
