An atelier of advertising

AI creative factory
Kelsmoor keeps its own AI production line. A strategist sets the direction, the models generate the film, and a person completes every piece. The result is a testing volume no conventional shoot could supply.

Services
For the CMO or founder who would sooner hold one house to account than referee three vendors.
Paid media
Planning, account builds, bidding and budgets, all held by us. Reports draw on your MMP data, never on screenshots.
How the buying is arrangedCreative
Batches of 20–80 finished video ads, from €363 per finished ad. They pass directly to the people buying your media.
Inside the workroomMeasurement
A campaign can only steer by its numbers, so the numbers are examined first. AppsFlyer or Adjust is installed and audited. SKAN values are mapped on iOS. Where attribution falls silent, incrementality is tested.
Follow one installMeta, Google, TikTok, Apple Ads or Snapchat records the event.
AppsFlyer or Adjust removes duplicates by checking store records.
The SKAN postback lands. Its conversion value translates into revenue.
A geo holdout separates true lift from coincidence.
The next budget and the next creative take their orders from the result.
The working cycle
Where the return sits.
Before any brief, we read your account, your listing and your site. We want three answers: who buys today, which angles have tired, how high the category bids.
A batch, never a single piece.
Each batch holds 20–80 finished ads, from €363 per finished ad. One polished asset teaches little. Variation is what makes a result legible.
The same people, on all seven channels.
A brief and its budget stay with the same people, on Google, Meta, TikTok, Apple Ads, Snapchat, Moloco and ChatGPT Ads. Nothing is passed along.
The return writes the next brief.
The figures from SKAN and the MMP are read, and they write the next brief. Taste has no vote.
Ads that belong in the feed and hold the thumb.
Appear at the moment someone types your category into the App Store.
Young viewers, the whole screen, and video that looks made for the place.
A place in the conversation, while the buyer is still asking questions.
A better listing turns more existing traffic into installs, before any click is bought.
Acquired users are expensive. Retention lets that cost go on paying back.
Many now ask ChatGPT or Perplexity instead of searching. We work to have your name in the answer, and measure it as we would a channel.
About Kelsmoor
The house has no single address. We work remotely, worldwide, with apps, games and ecommerce brands growing at pace.
01
Whether a campaign can grow is settled in the ad, so that is where we begin. Buying and measurement govern the rest: distance and pace.
02
Each of us has operated a live channel. The voice on your call belongs to the hands on your account.
03
Each decision comes with its evidence: spend, MMP data, attribution logic, incrementality tests. All of it is yours to read.
04
Our thinking, test plans and conclusions are set down in writing and shared.
Platforms and stack
The spend runs across these platforms and is measured in your MMP. You and we read the same figures.
FAQ
Practitioners. Account managers are not part of the arrangement. Whoever answers you has operated a live channel and makes the change personally. Spend, attribution and reasoning stay open to you.
A batch runs to 20–80 finished ads, from €363 per finished video ad. The range is deliberate. It gives each batch enough variation to teach something.
Both, by design, and within the same group of people. Video, UGC and AI-generated ads are made in batches of 20–80. The buyers on your account then read the results and order the next batch accordingly.
It is the line Kelsmoor runs for itself. The idea comes from a strategist. The video comes from AI. The finish comes from an editor, who cuts, subtitles and grades each ad. Batches of 20–80, from €363 per finished ad.
Seven: Google, Meta, TikTok, Apple Ads, Snapchat, Moloco and ChatGPT Ads. Those who write the brief also hold the budget, so no handover takes place.
As a discipline of its own. Your MMP, AppsFlyer or Adjust, is audited first, because nothing downstream holds without clean data. On iOS, each SKAN conversion value is tied to an event that foretells revenue. When attribution reaches its limit, an incrementality test takes over. Your dashboards and ours are the same.
