Which marketing agencies work with $100M+ ecommerce brands?

Very few agencies state a revenue ceiling or floor publicly, so the honest answer has to be read from their named clients rather than a published band. Agencies here with enterprise-scale named clients include Tinuiti (Carter's, DSW, Blue Apron), Mars United Commerce (Walmart, Campbell's, Conagra), Real Chemistry (large pharmaceutical companies), redpepper (Mars Petcare, Colgate), and Darkroom (Adobe, Amazon, Everlane). Named client scale is a proxy, not a commitment, so confirm which team would actually be assigned to you.

Which agencies work with brands under $5M in revenue?

Stryde publishes the narrowest band on this site, stating it works with D2C brands between $1M and $15M in annual revenue. Top Growth Marketing states a range from $100K to $25M+. Beyond those two, most agencies serving smaller brands signal it through retainer minimums rather than revenue bands, so ask for the minimum monthly fee and the minimum ad spend they will accept.

Why don't agencies publish the client size they work with?

Mostly commercial caution. A published floor turns away revenue the agency might have taken, and a published ceiling makes it look small. The practical effect is that buyers cannot self-select, which wastes time on both sides. The handful of agencies that do publish a band tend to be the ones confident enough in their positioning to lose the wrong fit deliberately.

What should I ask instead of 'do you work with brands my size'?

Ask for the minimum monthly retainer and minimum ad spend. Ask how many other clients the assigned team carries and what the largest and smallest are. Ask for two references in your revenue band and business model specifically, not just your category. Those three questions reveal fit far more reliably than any published range.

Choosing an agency by your revenue stage

Updated October 17, 2026 · Based on 37 agencies

The short answer

Only 3 of the 37 agencies we cover (8 percent) publish the client size or revenue band they serve. The rest say nothing, which means “do you work with brands my size” cannot be answered from any agency website, including the ranked lists that claim to sort agencies by who they suit. The reliable substitutes are minimum retainer, minimum ad spend, and the scale of named clients.

The agencies that publish a band

Agencies that publish the client revenue band they serve.
Agency	States it serves
Top Growth Marketing	Brands from $100K to $25M+ in annual revenue
Stryde	D2C brands with $1M to $15M in annual revenue
Theory House	Growth-stage brands

That is the complete list. Every other agency we cover is silent on the question.

How to read the signals that are published

Named clients set the ceiling, not the floor. An agency showing Walmart and Campbell’s logos can clearly service enterprise accounts. It tells you nothing about whether a $3M brand gets the same team, and usually it does not. Ask who specifically would be assigned.

Team size indicates the floor. A 20-person agency cannot afford to staff a $2,000 per month account badly and survive, so its minimum is usually real. A 500-person agency can take small accounts and park them with junior staff, which is the more common failure.

Percentage-of-spend pricing encodes a floor. An agency charging the greater of a base retainer or a percentage of spend has told you its minimum viable client size, whether or not it says so. Divide the base retainer by the percentage to find the spend level where it stops subsidising you.

Partner tiers correlate with volume, not fit. 10 of the agencies we cover publish a platform or retailer partner status. Those tiers are typically earned through managed spend or client count, so they indicate scale rather than suitability for your particular brand.
