How New York founders like FilterBaby produce 60 launch-ready ads a week — without a creative agency

Xin Shui and Lynn built FilterBaby from New York with a clear purpose: give parents a smarter, cleaner solution they can trust for their family. The product resonates deeply — parents who find it become loyal customers fast. But building a business on Facebook ads means you need one thing above all else: a constant, reliable stream of fresh creative. And that was exactly what Xin and Lynn couldn't produce fast enough.

🇺🇸 American parents are one of the most valuable — and most competitive — audiences on Facebook. Every major baby and home brand in the country is fighting for the same feed placement. The brands winning aren't necessarily the ones with the best products. They're the ones with the most ads in market, testing constantly, finding their winning hooks before their competitors do. FilterBaby had the product. They needed the volume.

Every time they needed new ads, the process looked like this: brief a freelancer or UGC creator, wait five to seven days, review content that was sometimes compelling and sometimes completely off-brief, go back and forth on revisions, receive files that needed reformatting for different Facebook placements. Nearly two weeks for one usable batch. At $400–$600 per round, that limited them to two production cycles a month — giving them eight to twelve creatives in thirty days.

Meanwhile, the Facebook algorithm was starving. Meta needs 30+ creative variations to properly identify winning audiences and angles. FilterBaby was feeding it ten and watching their CPA plateau — unable to scale their ad spend because no single creative was performing consistently enough to justify it.

“We were doing everything right — good product, good targeting, decent budget — but our CPA just wouldn't move. We eventually realised it wasn't the targeting. We simply didn't have enough creative for the algorithm to work with. And at $500 a batch and a two-week turnaround, we had no way to fix that quickly.”

— Lynn, Co-Founder, FilterBaby

As two founders wearing multiple hats, Xin and Lynn couldn't spend their time project-managing creative production. They needed to be focused on the business — on product, on customers, on growth. A workflow that consumed two weeks and $500 every time they needed fresh ads wasn't just expensive. It was a distraction they couldn't afford.

The first thing that changed was freedom. Xin and Lynn stopped thinking about creative production entirely — and started thinking only about results. In week one, this 🇺🇸 New York-founded brand had more creatives in active testing than they'd produced in the entire previous quarter. The two-week production cycle became a two-minute one. A new product launch, a seasonal push, a competitor running a promo — they could respond in real time.

With 30+ variants live simultaneously, Meta finally had the signal it needed. The algorithm found the winning hooks, the winning visuals, the winning audiences — and optimised hard. Within 30 days, CPA dropped 34%. Not because the targeting changed. Not because the product changed. Because FilterBaby finally gave Facebook enough creative to work with.

The $2,400 a month they were spending on freelancers was freed entirely. That money moved into Facebook ad spend — which compounded the results even further. Less overhead, more scale.
