Back in July 2025, I shared a product idea with a small group of newsletter subscribers.

It wasn’t trending.
It wasn’t being pushed by gurus.
No Twitter noise. No viral reels.

Just a product that made sense if you knew how to read demand signals properly.

This week, I stumbled across a store selling that exact category.

They’re now running 700+ Meta ads, pulling 100k+ monthly traffic, and conservatively doing ~$150k/month.

What stood out wasn’t the revenue.

It was how predictable the outcome was once you understand product selection.

Most people think they lose money because ads didn’t work.
In reality, they lose money because the product was wrong from day one.

To make this more concrete, I’ve attached the actual CSV I used back then to evaluate the product category.

Not as a “hack.”
Not as a shortcut.

But as proof that this wasn’t intuition or luck, it was structured filtering.

In the full blog, I break down:

  • Why this product was obvious months before it scaled
  • The exact patterns I look for before ever touching ads
  • Why chasing “winning products” is the fastest way to stay broke
  • How I filter ideas so I say no faster than I say yes

I didn’t share the store.
I didn’t share the product name for copying.

Because the value isn’t the product.

It’s the thinking process behind it.

If you’re serious about e-commerce in 2026, this is one of those reads that quietly upgrades how you think and saves you from expensive mistakes later.

Good research compounds quietly.
Bad decisions get loud quickly.
