Incrementum Digital Review 2026: The Only Agency Here With a Real Review Base

After reviewing nine affiliate and Amazon agencies, one thing is consistent: almost none of them can be checked. Public review counts run from four to thirty, which is not enough to judge anything.

Incrementum Digital is the exception. It carries a reported 4.8 out of 5 across more than 120 Trustpilot reviews, which is four times the largest sample of any other agency we have looked at. That alone makes it worth a separate article.

The evidence gap, closed

Why the sample size changes the decision. A 4.8 from 120 reviews and a 5.0 from nine are not comparable claims. The first survives a few unhappy clients and still reads 4.8; the second cannot contain a single bad experience by definition. When you are committing a five-figure annual budget, the larger number tells you far more about what a typical engagement looks like.

One caveat, stated plainly: Trustpilot collects reviews differently from Clutch. A Clutch review requires a verified client interview, which is a higher bar per review but produces far fewer of them. Both have value, and 120 of the easier kind still beats nine of the harder kind for understanding typical outcomes.

The retail media footprint, which is the real differentiator

Most “Amazon agencies” mean Amazon. Incrementum covers a retail media map that is unusually wide.

Instacart, Kroger, Ulta and Chewy are the interesting four. If you sell groceries, beauty or pet products, those are the retail media networks where your competitors are buying and where most agencies cannot help you. That is a narrower and more defensible pitch than “we do Amazon”.

What it costs

Pricing starts from a reported $2,500 a month, with full rates on request. That places it level with Advertise Purple as the most accessible entry point in this set, and below the $4,000 to $5,000 floors common elsewhere.

For an agency serving 500+ brands with a named client list including Ruggable, Martha Stewart, Samsonite and Faber-Castell, a $2,500 floor is low. That usually means tiered service levels, so the question is what $2,500 actually buys versus what those named clients are paying.

Data Owl, and what to ask about it

Incrementum provides Data Owl, a real-time ASIN-level reporting platform, to clients. ASIN-level granularity is the right unit for Amazon work: aggregate account reporting hides the fact that three products are carrying the account and forty are losing money.

What to press on

Incrementum Digital pros and cons

Who Incrementum Digital suits

A good fit if you sell in grocery, beauty or pet categories where Instacart, Kroger, Ulta or Chewy matter, or if you want an Amazon agency you can actually research before committing. On evidence available to a buyer, it is the best documented agency in this comparison.

A poor fit if you need the verified-interview standard that Clutch provides, or if you are only on Amazon and would rather have a pure specialist than an eight-network operator.

Incrementum Digital alternatives

The verdict

Incrementum Digital solves the problem that makes this whole category hard to shop in. Every other agency asks you to commit tens of thousands of dollars on the strength of fewer than thirty reviews. This one has more than 120, a published floor, named clients and a retail media footprint that covers networks almost nobody else touches.

None of that guarantees a good outcome on your account, and the usual diligence still applies: ask what the entry tier buys, how many clients they run on your specific network, and what happens to your Data Owl data when you leave. But you can at least start that conversation already knowing what a typical client thinks, which is more than this category usually allows.
