Walli Cases Grows Profit by 22% While Cutting Ad Spend by 37% Using Realtime’s Data-Driven Paid Media

Realtime & Walli Cases Collaborate to Drive Profitable Growth

Walli Cases makes premium phone cases with an emphasis on design, functionality, and performance. Walli Cases has established a successful eight-figure DTC brand that is known nationally for its style, quality, and purpose-driven design.

As of the start of this year, what the Walli Cases brand didn’t have was a paid media program as disciplined as the product. When Realtime’s ecommerce team took over Meta and Google in January, the account was doing what a lot of DTC accounts do: buying revenue. Spend was high, efficiency was thin, and blended ROAS had been trending downward. The topline looked healthy, but it wasn’t backed by real growth.

Realtime's Approach

We rebuilt Walli's paid media program around profit, not platform-reported ROAS. Comparing the first half of 2026 against the same stretch of 2025, our approach was built on three key pillars

Auditing Attribution and Identifying Waste

  • Walli’s previous setup was optimized for the wrong thing, chasing the revenue the platforms were happiest to report, much of which wasn’t incremental.
  • Branded search clicks and retargeting impressions were served to people already on their way to checkout. Walli was paying to take credit for sales it had already won.
  • The measurement infrastructure made this harder to see: Meta claimed sales that had actually come through email and organic, and Google claimed the same attribution.
  • Reported revenue across paid channels was 3x actuals in Shopify.
  • Taken at face value, on their own measurement terms, the platforms all looked unbelievably strong, emphasis on the unbelievable part.
  • Digging into Walli’s actual Shopify numbers told a different story: flatter, more expensive, and less productive than certainly the platforms would like to admit.
  • Realtime’s read going in was blunt: spend a lot less, while simultaneously driving efficiencies to grow incremental revenue. That’s revenue Walli wouldn’t otherwise earn if not for that efficient, productive spend.

Rebuilding Measurement Around Profit

  • Every figure came from a third-party attribution system sitting on top of real Shopify orders, not an Ads Manager report on revenue that grades its own homework.
  • We place trust in third-party measurement tools because they don’t have skin in the game, and they allow us to measure what is actually driving performance and growth.
  • We held ourselves to numbers Walli’s finance team already trusted.

Protecting Acquisition While Cutting Waste

  • In practice, that meant aggressively cutting spend wherever it was buying sales that would have otherwise been driven without paid media investment.
  • And holding the line wherever spend was genuinely acquiring new customers and purchases.
  • The easy way to make an account look efficient would have been to retreat into retargeting and warm audiences, watch ROAS climb, and let acquisition quietly die in the background. We did the opposite.
  • We kept pushing on new customers while stripping out the waste, so the efficiency we gained was real and truly incremental.

New Customer ROAS

That’s what Realtime delivered for Walli: ad spend down more than a third, revenue essentially unchanged, and profit up 22%. Holding revenue steady while pulling that much spend out means the money coming out was never earning its keep in the first place. And new customers got both cheaper and more profitable to acquire along the way.
