The Client
An e-commerce brand that needed a partner, not a project
Our client is a Singapore e-commerce brand in a competitive consumer category. They had seen agencies deliver an early spike and then coast — leaving performance to slowly decay. They wanted a partner that would keep testing and keep them ahead, year after year. In a competitive consumer e-commerce category, the hard part is not the first win — it is the fifth year. Most performance plateaus or decays over time: audiences fatigue, winning creatives wear out, competitors copy what works, and platform costs creep up, so an account that is merely maintained slowly slides backwards. This brand had felt exactly that pattern with previous agencies — an early spike as the obvious inefficiencies were fixed, then a long, quiet decline as the work settled into autopilot. What it wanted was the opposite of autopilot: a partner that treated the account as something to be actively defended and extended every quarter, not set and forgotten. Sustained growth in e-commerce is won by whoever keeps testing — new audiences, creative, offers and channels — faster than the market erodes the old wins. The brand needed that engine of continuous improvement, and the discipline to keep running it long after the easy gains were gone. It is worth being clear about what that requires: not a flashy relaunch, but the unglamorous discipline of measuring, testing and reallocating every single quarter, holding the bar high even when the numbers already look good. That is precisely the work most agencies stop doing once a contract feels comfortable — and precisely the work this brand wanted a partner to never stop doing.

The Challenge
Early wins that didn't last
Three patterns kept eroding the brand’s results over time.
Problem 01
Set-and-forget campaigns
Once initial gains landed, optimisation stopped and performance quietly declined.
Problem 02
No testing culture
Creatives and offers went stale because nothing new was being tested against them.
Problem 03
Falling behind the platforms
Ad platforms change constantly; static accounts steadily lose efficiency to competitors who adapt.
Our Strategy
A test-and-iterate partnership
We treated growth as ongoing — a constant cycle of testing, learning and staying current across channels. So we built the partnership around a simple operating rhythm: never let the account coast. Every quarter we revisited the entire strategy against fresh data — retiring creatives and campaigns as they faded, doubling down on what was proving out, and continuously testing new audiences, offers and channels before the current winners had a chance to decay. Rather than chase one big idea, we compounded many small, evidence-led improvements, each protecting and extending the gains of the last. Over three years that discipline did what one-off optimisation never could: revenue grew 260% and the account held a 4.5 times ROAS sustained across the entire period — not a single good quarter, but years of consistent, profitable growth. The brand kept pulling ahead of its category precisely because the work never stopped, turning a marketing account into a durable, compounding competitive advantage.
Always-on testing
Ran continuous creative, audience and offer tests so the account kept improving, not plateauing.
Stay current by design
Adopted new ad formats, signals and platform features early to keep an efficiency edge.
Quarterly strategy resets
Revisited strategy every quarter against fresh data, retiring what faded and scaling what worked. For a related example, see our Google Ads case study.
The Results
Measurable outcomes that changed the business
Three years in, results were still climbing, not coasting — a partnership that compounds instead of fading. The deeper lesson of the engagement is that in e-commerce, consistency beats brilliance: a partner willing to keep testing quarter after quarter will outperform one chasing the occasional big swing — and over three years that gap compounds into a decisive lead.
