From Meta Ads to Google Ads to Click-to-WhatsApp funnels, we build direct response growth systems that turn cold attention into qualified leads — measured against ROAS and CPA, never vanity metrics.
Our Story
We believe great advertising doesn't sell products — it lowers your CPA. Based in Hong Kong, CLS Studio builds direct response growth systems for brands that want measurable returns, not vanity metrics. Every campaign, funnel, and creative asset we ship is engineered to turn cold attention into qualified leads and paying customers.
Rooted in performance and backed by data, we partner with brands that are done with pretty-looking marketing that doesn't move the needle. Whether it's a buyback campaign that needs 10x ROAS, a lead funnel that needs lower cost-per-lead, or a Click-to-WhatsApp flow that needs to convert — we bring media buying, creative, and analytics under one roof.
Our Mission
We exist to build marketing systems that turn attention into revenue — ad by ad, click by click, customer by customer.
- 1 — Numbers Over Noise
No fluff, no vanity metrics. Every recommendation we make is backed by ad account data, CPA benchmarks, and real ROAS numbers from our live campaigns.
- 2 — Sell, Don't Preach
Every creative has one job: stop the scroll, hook the pain, trigger the click. If it doesn't sell, we kill it and test the next one the same week.
- 3 — Ship Fast, Learn Faster
The best-performing ad is the one you haven't tested yet. We run weekly optimizations, not quarterly reviews — because momentum beats perfection, every time.
