Why Kelkoo
The operating model retail leaders actually need
We replace fragmented agency relationships with a single, senior team accountable to one number: profitable, sustainable revenue growth.
01
Senior practitioners on every account
You work directly with strategists who have run nine-figure budgets — not a layered hierarchy of juniors. Average team experience: 11 years.
02
Transparent reporting, no black boxes
You own the data, the accounts, and the playbooks. Daily dashboards, monthly business reviews, and full visibility into spend and outcomes.
03
Built for retail economics
Optimisation against contribution margin, lifetime value, and inventory health — not just last-click conversions.
04
Compounding test velocity
An always-on experimentation programme across creative, audiences, and landing pages. Measurable improvement, every quarter.
Our Process
How we engineer growth in 90 days
A disciplined onboarding designed to compound. Most clients see meaningful efficiency improvements inside the first quarter.
STEP 01
Audit & Diagnose
Forensic review of accounts, attribution, creative, and competitive positioning. We surface the leaks before scaling spend.
STEP 02
Strategy & Forecast
A revenue plan with clear assumptions, channel mix, and a financial model your finance team can actually use.
STEP 03
Build & Activate
Account restructure, creative production, and tracking infrastructure — launched in weeks, not quarters.
STEP 04
Optimise & Scale
Continuous experimentation, weekly optimisation cycles, and quarterly business reviews against agreed targets.

In Their Words
What operators say about working with us
Kelkoo is the rare partner that talks margin, not impressions. They rebuilt our paid programme around the metrics our board cares about, and the impact was visible inside the first quarter.
EW
Elena Whitcomb
Chief Marketing Officer, Marbella Living
We replaced three agencies with Kelkoo. The reporting clarity, the seniority of the team, and the discipline of the testing programme are simply on a different level.

Rohan Aggarwal
VP of Growth, Northvale&Co
For a brand expanding into new geographies, having one partner who can model the opportunity, build the launch plan, and execute it across channels is invaluable.
