The challenge

Why Not Natural built a profitable Amazon supplement business but couldn't translate it to DTC. A media-buyer-only setup left them with thin creative, ~$60 CACs, and three months of a dormant Meta account before hiring N17.

"We did not have a good pipe of new creative. That was the bottleneck. We barely had any statics, and video was even worse."

What we did

  1. 01

    Hybrid creative engine

    Statics first to find winning angles fast and cheap, then video built on the proven concepts. No more waiting weeks on a single asset.

  2. 02

    Structured landing page splits

    Tested page variants head to head until one cleared the field, then routed paid traffic to the winner.

  3. 03

    Daily KPI and P&L reporting

    Every scaling decision tied to contribution margin and net margin, not platform ROAS. Spend only went up when the bottom number supported it.

  4. 04

    Retention alongside paid

    Email, SMS, and subscriptions built out in parallel so every acquired customer compounds instead of churning.

The creative

Statics shipped first to find angles fast: offer-led, ingredient-led, and credibility-led concepts tested side by side. Winning concepts graduated to UGC video. A sample of what ran:

Static ad for Why Not Natural liquid D3 K2
Static: Liquid D3 + K2, ingredient-led
Static ad for Why Not Natural magnesium complex, buy 2 get 1 free offer
Static: Magnesium Complex, offer-led
UGC video: Liver Support

The landing page

Winning Why Not Natural landing page for Magnesium Complex

Paid traffic went to structured page splits, not the homepage. Variants ran head to head until one cleared the field, and that winner now carries the Magnesium Complex push.

"We were not very sophisticated when it came to landing pages, but we tried different versions and I think we found a winner. That's been one of the two biggest things that's changed."

"You guys really dig into the proper P&L for the channel itself. It's not just spend and we only look at the top number. I very much appreciate that you also look at the bottom number. And the daily reporting as well, we really like that. It's a great tool to be able to track where we are and where we're going."

Spend vs revenue, Sep 2025 to Apr 2026

Monthly Meta spend up 15×. Monthly revenue up 2.4×. The gap between the lines is the point: spend scaled only as fast as the P&L allowed. Dollar values withheld at the client's request.

The results

Seven months in, monthly revenue is 2.4× where it started while Meta spend scaled 15× against daily contribution margin reporting, with the most recent month setting the spend record. The DTC push lifted two SKUs on Amazon as a halo effect. The account that sat dormant for three months is now the brand's growth engine.

"The two products that we've been pushing the most, sales are up on Amazon. That's why I'm okay to push ads at an MER that maybe wouldn't make sense just on Shopify only."

Loic Marquet
Co-Owner, Why Not Natural

"I see you guys more like a fractional CMO. You look at the full picture. We get a daily P&L on everything Shopify and Meta. It's a full global approach: the landing pages, all the creatives, even the email and the subscriptions. You literally look at everything. It's very refreshing."
