Pinterest Isn't Just for Mood Boards Anymore

One Q4 campaign changed how Acceler8 Labs thinks about the platform entirely

There's a version of this story that's pretty simple: brand runs holiday campaign, brand gets good numbers, brand is happy. But what happened with KaseMe during Q4 2025 is worth unpacking a little more carefully — because it says something useful about where Pinterest is right now as a performance channel.

KaseMe sells phone cases, tech accessories, and everyday gadgets. Not the most obvious fit for a platform historically associated with wedding planning and home decor.

But holiday shopping is a different animal. Consumers are in discovery mode, purchase intent is high, and the line between "inspiration" and "I want to buy that" gets very thin very fast.

That's exactly the environment Pinterest Performance+ was built for. And the numbers from KaseMe's Q4 campaign make a pretty compelling argument that the product delivers.

By the Numbers

What Actually Ran

The campaign wasn't one format — it was a mix: static ads, collection ads, and shopping ads, all running under the Pinterest Performance+ catalog sales objective. That combination matters. Collection and shopping ads are designed to shorten the path from product discovery to checkout, which is exactly what you need when someone is browsing for gift ideas and you want them to stop scrolling and start buying.

Performance+ does the heavy lifting on targeting and delivery optimization, which means the team didn't need to micromanage audience segmentation. The algorithm found the buyers.

Why This Should Be on Your Radar

The easy takeaway is "Pinterest works for Q4." That's true, but it's also underselling it.

What this campaign demonstrates is that Performance+ can drive real efficiency gains — not just volume. A 23% drop in CPA alongside a 25% lift in checkout conversion rate means the campaign wasn't just reaching more people; it was reaching the right people at the right moment.

For brands in tech accessories or any category where the product is inherently giftable, the Q4 Pinterest window is worth serious budget consideration. And for brands already running Meta and Google, Pinterest often represents an untapped incremental audience — shoppers who aren't responding to ads elsewhere but are actively in discovery mode on the platform.

Our Acceler8 Labs Co-Founder Uzair Chutani put it directly:

"This was such an exciting season for the KaseMe and Acceler8 Labs teams. Pinterest Performance+ catalog sales turned holiday momentum into the kind of measurable wins that earned Pinterest a permanent place in KaseMe's media mix and across our roster of clients at Acceler8 Labs."

That last part is the signal worth paying attention to: this wasn't a one-off test. It changed how the agency thinks about channel allocation across their entire client base.

Quick Takes: Platform Updates That Matter

Pinterest Performance+ Catalog Sales

  • What it is: Pinterest's AI-powered campaign type that automates targeting and creative delivery for catalog-based advertisers

  • Why it matters: Removes the manual overhead of audience segmentation while optimizing toward conversion events — a meaningful advantage during high-volume periods like Q4

  • What to watch: How Performance+ scales outside of holiday peaks; early signals suggest strong year-round viability for the right verticals

The DTC beauty category is crowded. To break through, Jennifer Anniston’s brand LolaVie, worked with Roku Ads Manager to easily set up, test, and optimize CTV ad creatives. The campaign helped drive a big lift in sales and customer growth, helping LolaVie break through in the crowded beauty category.

The Other Thing Driving Results: Agency Setup

The KaseMe campaign is a good example of a channel working.

But there's a secondary lesson worth naming — one that shows up in most performance success stories and almost never gets credit.

After years at Meta and now running Acceler8 Labs, our founders have seen the same pattern play out across enough brands to call it by name: most "agency performance problems" aren't agency problems.

They're setup problems.

The brand hires an agency with vague goals. Gives them limited creative. Disagrees on measurement. Then blames the agency six months later. Rinse and repeat.

What a functional agency relationship actually requires isn't complicated, but it does require intention on the brand side:

1. Define clear goals. Specific revenue targets by quarter, channel-level benchmarks, and milestones at 30, 60, and 90 days. "Grow the business" isn't a brief.

2. Bring real creative. A brand brief, product positioning, approved messaging, and enough assets to actually test with. If your creative pipeline is dry, performance will be dry. No algorithm fixes that.

3. Agree on measurement upfront. What metrics matter? What's the reporting cadence? How will both sides know if this is working? Settle this before the campaign launches, not after it underdelivers.

4. Be honest about your gaps. Holes in positioning, messaging, or product-market fit don't disappear when you hand things off to an agency. Acknowledge them. Work on them in parallel. Don't ask your media partners to paper over a conversion problem with more spend.

When those four pieces are in place, agency performance improves dramatically. Not because the agency got better — because they finally had the foundation to do their job.

The KaseMe campaign delivered because the brief was clear, the creative was there, and both teams were aligned on what "winning" looked like.

The 13x ROAS was the output of that setup, not a lucky outcome.

Last Word

"Set your partners up to win. They'll return the favour."
