About Kelkoo

Built by retail operators, for retail operators

We started Kelkoo because we kept seeing the same gap: brilliant retail brands paired with agencies that could not connect their work to commercial outcomes. So we built the partner we wished we had.

Our Story

A practitioner-led firm with one obsession

Kelkoo was founded in 2014 by a small group of senior in-house operators who had spent the prior decade running paid media, retail media, and commercial teams inside high-growth retailers and global brand groups.

We were tired of an industry that confused activity with impact, that hid behind black-box reporting, and that staffed accounts with people who had never owned a P&L. We started Kelkoo as the antidote: senior, transparent, and accountable to the metrics that actually move the business.

Today we partner with retailers, e-commerce brands, and selected agencies across North America, Europe, and Asia-Pacific — operating as an extension of their commercial team rather than an external vendor.

Mission

To make performance marketing measurably honest again

We believe modern retail leaders deserve a partner who treats marketing as the financial discipline it has become — and who has the operational seniority to back it up.

Our Values

Five principles that shape the work

Outcome over activity

Every brief, every report, every meeting begins with the commercial outcome. Activity is only relevant insofar as it serves it.

Seniority on every account

The people who win the work are the people who do the work. No bait-and-switch staffing, no junior-led delivery.

Transparency by default

You own the accounts, the data, and the playbooks. We show our working — the wins and the misses — every week.

Discipline over fashion

We resist trend chasing. Channel diversification, creative testing, and measurement rigour have built more brands than any new platform ever has.

Long horizons, fast loops

We plan in years, ship in days, and learn weekly. The combination is what compounds into category-leading performance.

Care for the craft

We hire and develop people who genuinely love this work. The standard for quality is set by them, not by a process document.

Leadership

The principals you'll actually work with

The Kelkoo leadership team remains directly involved in every major engagement — by design, not by exception.
