Acorn vs Flywheel vs reMKTR: Three Bets, Three Axes

Four things are called Acorn, so name the one you mean

This is the rare comparison where disambiguation is the most valuable paragraph on the page, because the search results for this term belong mostly to companies that cannot do the job at all.

• Acorn-i — the Amazon and ecommerce agency. This page is about them.
• Acorn by New Engen — a creator marketing suite. It supplies creators and content, not media buying. Putting it on a media shortlist produces a candidate that cannot bid.
• Acorns — the consumer investing app. Enormous search volume, no relevance.
• Acorn TV — the streaming service.

If a comparison article you are reading does not open by separating these, check which one it is describing before you trust anything else in it. We have seen shortlists where one row was a creator platform and nobody had noticed for a fortnight.

With that settled, two matchups account for nearly every real version of this question: a specialist against a holding-company practice, and either of them against a partner that buys one thing and is measured on it.

What the ownership record actually says, because it says two things at once

Acorn-i's corporate history is reported in a way that trips up almost every page written about it, and getting it wrong makes a live business sound closed.

Both of the following are true. The Brandtech Group took majority ownership in June 2022, and a November 2023 announcement described combining Acorn-i with Jellyfish to create Jellyfish Commerce — that announcement is real and it is well documented. At the same time, acorn-i.com is live and trading today, describing itself as a technology-led ecommerce agency built around its Ignite platform, and making no mention of Jellyfish or Brandtech anywhere on the site.

So do not write off the company, and do not assume the entity you would contract with is the one in the press release. The practical move is the one that applies to any firm mid-transition: ask which legal entity signs the agreement, which team is assigned, whether the people in the pitch are the people on the account, and what happens to your contract if the group reorganises again.

That question is not specific to them. Renames and absorptions are constant in this category — ChannelAdvisor is now Rithum, Kenshoo is Skai, Sunken Stone is Emplicit, Carbon6 went to SPS Commerce, and Flywheel became an Omnicom practice area. A reference or a review written before any of those events is describing an organisation that no longer exists in that form. Date every signal you rely on.

Acorn-i: technology-led, and genuinely good at a specific thing

Founded in 2018 by Amazon alumni, and built around Ignite, an analytics application consolidating marketplace, Amazon, direct-to-consumer and advertising data into a single view.

The strength is real and specific: an operating culture that starts from account data rather than from a media plan. Amazon Ads published a case study crediting Acorn-i's hourly retail analytics on the pet food brand Naturediet with a 27% increase in return on ad spend in Q1 2023 and a 90% cut in campaign optimisation time. Whatever weight you place on any single case study, the method behind it — reading retail performance by hour and acting inside the day — is a materially more demanding way to run an account than weekly bid reviews, and most firms do not attempt it.

Who they suit better than us, plainly: brands whose Amazon business spans the United Kingdom and several European marketplaces, who want the digital shelf, the content and the media handled by one team with analytics underneath it. We are not that. A brand with catalogue and content problems across five European storefronts would be worse off with us than with them, and pretending otherwise would waste a call.

Flywheel: the commerce practice with the widest reach

Omnicom acquired Flywheel from Ascential for a net cash price of approximately $835 million, announced at the end of October 2023 and closed at the start of January 2024. Omnicom's own release described a business of more than 2,000 professionals serving over 4,500 brands across retail commerce operations, media execution and market intelligence.

What that buys a client is coverage and continuity: hundreds of marketplaces, a market-intelligence heritage that predates the retail media boom, procurement and governance processes built for enterprise, and the ability to staff a global account without subcontracting. For a brand running Amazon, Walmart, Target and international marketplaces at once, that breadth is not a nice-to-have, it is the product.

Who they suit better than us: enterprise advertisers needing one contract across many retailers and many countries, with the compliance, security and reporting apparatus a large organisation requires. If your review process involves procurement, information security and six stakeholders, a firm at that scale is built for it and we are not.

The honest trade — and it applies to every large practice, including the large parts of our own group — is that seniority gets allocated. Ask which named people are on your account weekly, and how many other accounts they hold. That question is not hostile and the answer is not confidential.

reMKTR: narrower, and measured on one thing

We buy Amazon DSP — the demand-side platform for programmatic display, video and audio, not Delivery Service Partner, the courier franchise — as a managed service on our own seats. We are part of Full Circle, a full-service Amazon management company with $500M+ in managed spend across 100+ brands, and we hold 109 live Amazon DSP advertiser seats.

The most recent read is a live API pull across 27 advertiser seats over 31 days, 15 July to 14 August 2026: 5.12x on $732,916 of spend, a $6.83 cost per attributed purchase across 107,376 purchases, 31.4% new-to-brand, from 197.7 million impressions at a $3.71 CPM. That window and that advertiser count travel with the figures everywhere we quote them, because a different window and a different advertiser set produce legitimately different numbers.

What we do not do: catalogue and content operations across many European marketplaces, creator sourcing, or a single contract covering four retailers on three continents. On those, the other two are better answers and we would say so on the call.

Two honest redirects. Dr. DSP when you want the same display capability as a product your own team runs rather than a service you hire — and note that Orbit, included with it, is not a DSP and is not a substitute for the platform. Full Circle when the constraint is wider than media — listings, catalogue, supply chain — and display is only the symptom you noticed first.

Proof is the axis that separates fastest, so here is ours from the inside

Every candidate in this category can be placed on three axes: scale, seniority and proof. The first two are visible from the outside. The third is where the shortlist actually resolves, and it is the one most often answered with a chart.

So here is what proof looks like when you have the underlying data, from that same 31-day pull across 27 advertiser seats. All three of these are portfolio aggregates with no single advertiser identified.

A portfolio return is close to meaningless as a forecast. Across those 27 advertisers in the same 31 days, individual returns ranged from 0.85x to 18.03x, with a median of 4.30x. Sixteen of the 27 cleared 4x and the rest did not. Our own blended 5.12x is pulled upward by a handful of accounts with strong retargeting pools. When any vendor quotes a portfolio figure — us included — the honest follow-up is what the median account did and how wide the distribution is.

Prospecting and retargeting cannot share a target. Prospecting cost 2.7 times more per customer than retargeting in that pull — $12.13 against $4.47 — and produced a 46.6% new-to-brand rate against 29.2%, on roughly equal spend. Read as return, prospecting looks like the loser; read as customer acquisition cost, it is a $12 new customer. Which reading is correct depends entirely on repeat purchase rate, which is why consumable categories tolerate a prospecting budget that hard-goods categories cannot.

Streaming will always fail a retargeting target. Streaming and connected-television inventory returned 0.77x in that window and delivered the highest new-to-brand rate on the whole report at 56.3%, at CPMs of $15.51 against $3.71 portfolio-wide. Judge it on the retargeting target and it gets cut, and cutting it removes the part of the plan that produces first-time buyers. Set its target before the first impression serves.

The test question to put to all three candidates, and to us: describe the design of the last incrementality test you ran — what was held out, for how long, who computed it, and what did you conclude when it did not work?

Running the bake-off without rigging it

Comparisons in this category usually fail on process rather than judgement. Five rules keep it fair.

Give every candidate the same brief and the same data access. A firm working from a fuller export will look sharper for reasons that have nothing to do with capability, and afterwards you will not be able to tell which was which.

Agree the measurement definition before anyone starts. Attributed sales, incremental sales and total account sales tell three different stories about the same fortnight, and whichever one you accept in the pitch is the one you will be arguing about in month nine.

Segment the comparison. Retargeting against retargeting, prospecting against prospecting on cost per new customer, streaming on its own target. A single blended number across all three will pick whichever candidate happened to be handed the warmest audience.

Set the same window and the same definition of failure. Ninety days is usually the shortest honest read for display. Ask each candidate to write down in advance what result would make them recommend stopping, and keep the answer.

Price last. A quote is meaningless until you know what is inside it: whether media is inclusive of fees, what creative production costs, whether the seat is yours or theirs, and what the rate does as spend grows.
