You've been staring at heatmaps for 3 weeks.

You know users drop off at the pricing section.
You know the hero gets 40% scroll depth.
You know the CTA button gets clicked 1.2% of the time.

You just don't know what to do about it.

That's not a Hotjar problem. That's a decision problem.


Hotjar is brilliant at showing you behavior.
It cannot tell you which behavior to fix first.

So you end up with:

Sound familiar?


Here's what actually happens when founders get data without a decision engine:

They optimize the wrong thing.

They fix the button color because it's easy.
They rewrite the hero because it's fun.
They A/B test the CTA because it feels scientific.

Meanwhile the real problem — the one that's actually killing conversion — sits untouched in session recording #47.


CoSt doesn't replace Hotjar.

It answers the question Hotjar can't:

"Given everything I know about my site, my market, and my ICP — what is the ONE thing I should ship this month?"

Not a list. Not a dashboard. One bet.

With a Kill List of everything we rejected — and exactly why.

(For a full side-by-side comparison, see Hotjar vs. CoSt.)


The workflow that actually works

  1. Hotjar → understand what's happening
  2. CoSt → decide what to fix first
  3. Ship → come back to Hotjar to measure

Data without decision is noise.
Decision without data is a guess.

CoSt gives you the decision.
Hotjar gives you the proof it worked.


If you're using Hotjar and still don't know what to focus on this month — that's exactly what CoSt is for.
