One Tool That Secretly Fixed Most of My CRO Problems

You need to see this.

For a long time, I thought most CRO issues came down to judgment.

Bad test ideas.
Overconfident conclusions.
Teams moving too fast.

But looking back, most of the friction showed up somewhere else.

Tests ran longer than they should have.
Other tests never had enough traffic to answer the question in the first place.
Results were technically correct but hard to explain.
Old experiments faded into memory and then quietly repeated.

None of this is obvious from the start.

What changed things wasn’t a new framework or a better intuition. It was having one place where planning, analysis, and memory lived together.

I started planning tests before running them, checking whether the lift I cared about was even detectable, and saving the outcome somewhere I could actually find later. That alone removed a lot of unnecessary uncertainty.

Here’s what I’ve been using for that: https://lab.growthlayer.app

The most noticeable difference was upstream. I stopped running tests that couldn’t realistically succeed. Duration stopped being a guess. Expectations were clearer before anything shipped.

Downstream, conversations changed too. Results didn’t need defending as much. Context didn’t need rebuilding. When someone asked whether we’d tested something before, the answer was usually already there.

None of this made the work more exciting. It made it simpler and less stressful.

Less noise. Fewer reruns. Fewer “we’ll know in a few more weeks” conversations.

It didn’t change how I think about CRO. It just removed a layer of friction that I’d quietly accepted as normal.
