Independent E-Commerce Market Data for Agencies

The Problem

Every Pitch Starts With a Research Sprint Nobody Bills For

A pitch deck or a quarterly client review needs a market size, a retailer ranking or a trend line, on a deadline that does not allow for primary research. Public sources and best guesses are slow, and they are the first thing a sharp client questions.

The data you already have, next to the data ECDB adds

What That Costs an Agency

Without ECDB

Pitch Prep That Eats the Margin

Every new business conversation starts with days of unbilled research.

With ECDB

Pitch Prep That Protects the Margin

Preparation for any prospect is ready before the first call.

Without ECDB

Budgets Split by Habit

Nobody has sized where demand sits, so you follow last year's plan.

With ECDB

Budgets Split by Demand

Budget follows where category revenue is growing this year.

Without ECDB

Results Without Market Context

A 10% sales lift reads differently in a slower or faster growing market.

With ECDB

Results in Market Context

Every sales lift is measured against actual category growth.

Our Solution

One External Source Behind Every Account

Because ECDB is independent of the client and of the retailers it covers, a figure from it carries weight in the pitch and in the review precisely because nobody chose it to make a point.

The question you start with, and the data dimensions ECDB adds to answer it

Same Method for Every Client

A market slide built for one prospect works unmodified for the next, no fresh research sprint each time.

Budget Follows Measured Demand

Market and retailer allocations can be argued from GMV and growth, not from last year's split.

Performance in Market Context

Client results sit next to category growth, so a campaign is judged against the market it ran in.

Example Use Cases

Start With the Question Closest to Your Job

These are among the places agency teams most often start. Each one is a worked example on a real market and category, and each one combines two of the four datasets above.

Pitch & New Business

Example

France Consumer Goods

Know the Prospect's Market Before They Brief You

"What can we tell a prospect about their own market before the first meeting?"

You can open the first meeting with the prospect's own market. ECDB sizes online Homeware in France at about €1.5 billion, with its trend and leading stores, all ready before any client data arrives.
The trend gives you a growth story to pitch. Your prospect would be investing in a market that is growing again.
The ranking shows where the category is decided. The top five stores are all marketplaces, cross-border platforms or a flash-sale club, which makes platform management the core of any homeware strategy in France.
That turns the market slide into your agency's case. A brand whose sales run through these platforms needs marketplace and retail media expertise, so your capabilities follow directly from the prospect's own data.

Retail Media Planning

Example

Germany Consumer Electronics

Put Retail Media Budget Where the Category Actually Sells

"Our client spreads retail media evenly across five retailers. Is that where their category actually sells online?"

An even split puts too little behind the retailer that sells the most. Amazon sells about eight times as much in the category as MediaMarkt, so equal shares leave most of your client's sales underfunded.
Weight the base budget by category sales. That moves the largest share to Amazon and gives your client a split it can trace back to the market.
Put test budget behind MediaMarkt. After two weak years, it grew fastest of the four in 2025 at about 16%, so extra spend there builds on momentum that's already under way.
Bring Notebooksbilliger and Cyberport down to their size. Both sell a fraction of what Amazon does and grew more slowly than MediaMarkt in 2025, so an equal share overspends on both.

Campaign Rollout

Example France, Spain, Italy Fashion

Which Markets Deserve the Next Euro of Campaign Budget?

"The client wants to roll the campaign out in three more countries. Which ones actually justify the spend?"

Spain earns the first euro. It's smaller than France, but it has grown every year since 2022 and is forecast to add about €1.2 billion by 2027, more than France's €0.8 billion. Your client's campaign money meets the most new demand there.
France comes second, for reach. It's the biggest market of the three but still below its 2021 level, so budget there buys audience size more than growth.
Italy comes last, unless your client already has an established base there. It's the smallest market, and its growth is flattening, with only about €200 million added by 2027.
That order gives your client a rollout plan it can trace back to the market. All three countries are measured the same way, so the discussion stays on the plan.

Client Reporting in Context

Example

Netherlands Beauty & Personal Care

Report Client Growth Against the Market It Ran In

"Our client grew 9% online this year. How does that compare with the category, and with the retailers that set its pace?"

Your client's 9% is a clear win. The Dutch market grew 3.8% in 2025, so your client grew more than twice as fast and gained share. Presented that way, the review shows market share won, beyond the growth figure itself.
Next year's target needs to stay well above the market. Growth has picked up every year since 2024, and the forecast holds it at about 4.5% through 2027. Your client keeps gaining share only if it keeps outpacing a market that is speeding up.
The retailers that set the pace all belong to one group. Etos, bol.com and Albert Heijn lead the category across channels, and all three are part of Ahold Delhaize.
That makes one negotiation your client's most important of the year. Treat Ahold Delhaize as one account across three channels, and use the share gain as leverage for better listings.

Success Stories

Same Job. Same Reporting Line. Same Problem.

Three agency teams describing what changed once pitches, plans and client reviews ran on one consistent, independent source.

Mid-Size Marketing Agency

Europe

Pitch decks used to take a week of desk research just to get a defensible market slide. Now that's a starting point, not a deliverable.

Strategy Director

Before: New pitches needed a fresh market slide every time, assembled from whatever public sources existed for that category.
What Changed: A standard market sizing and retailer slide template, populated from the same source.
Result: Pitch turnaround time dropped, and the market slide stopped being the part prospects pushed back on.

Retail Media Agency

DACH

We moved a third of a client's retail media budget once we could show where their category actually sells.

Head of Retail Media

Before: Retail media budgets were split across retailers by habit and by which platform had the strongest sales team.
What Changed: Allocation reviewed against category GMV and growth by retailer, refreshed every cycle.
Result: Budget shifted toward two faster-growing retailers the client had been under-investing in.

Global Media Agency Network

Global

We run the same benchmarking format for every client now, which means we're actually getting better at it.

Head of Insights

Before: Each account team sourced its own market data independently, so nothing learned on one client transferred to the next.
What Changed: A shared reporting template built on one data source, reused across accounts.
Result: Market-context reporting is now a recognized part of the agency's offer, not a one-off analysis per client.
