Creative formats

NoteThe ads on this page are drawn for illustration. Each batch is made to your brief, your product and the placements you buy.

Creative formats we produce

Six formats cover most of what leaves the factory. Each is built for the placement it runs in, cut to 9:16, 4:5 and 1:1, and finished by hand before it goes live.

9:16Drawn vertical video ad: a figure stretching at sunrise, subtitles reading Three minutes. Every morning., and a call-to-action bar.
Fig. 1Vertical videoA hook in the first two seconds and subtitles burnt in, built for Reels, Shorts and TikTok.
9:16Drawn UGC ad: a creator speaking to camera, with word-by-word subtitles reading honestly didn’t expect this to work.
Fig. 2UGCCreator-led takes, scripted around a single claim and shot to feel native to the feed.
1:1Drawn motion ad: kinetic type reading Level 12 unlocked inside a progress ring, above an animation timeline.
Fig. 3MotionKinetic type and product motion for games and apps, where the mechanic is the message.
4:5Drawn static ad: a product bottle on a plinth, the headline The weekend edit, a twenty per cent badge and a Shop now button.
Fig. 4StaticSingle-frame ads for feeds and Shopping, where one line and one image have to carry the sale.
1:1Drawn carousel ad: a stack of swipeable cards, the first asking the viewer to pick a monthly, annual or family plan.
Fig. 5CarouselSequenced cards that walk a buyer through a choice, one frame at a time.

FinishingEvery ad passes through a person’s hands before it ships: the edit, the subtitles and the colour.

Brief in, ads out, straight into your campaigns

Our own AI creative production line. Strategists write the brief, AI produces the video, and people finish every single ad. It is how ambitious brands test at a volume that a traditional production schedule cannot reach.

Playbooks

MethodOne number per playbook. If it does not move, the spend does not scale.

Playbooks for apps, games and ecommerce

Four starting points, each built around the one number that decides whether spend can scale.

  1. Apps

    D30 ROAS

    The number we steer by

    Subscription and dating apps on Meta, Apple Ads and Moloco

    Bids and briefs follow thirty-day return, so the account buys subscribers who stay rather than trials that lapse.

    Talk about your account
  2. Ecommerce

    ROAS

    The number we steer by

    Ecommerce brands on Meta, Shopping and TikTok

    Return on ad spend read by product line, with creative refreshed before the feed tires of it.

    Talk about your account
  3. Games

    D7 ROAS

    The number we steer by

    Mobile games with AI creative batches and UA

    Seven-day return decides which batches scale and which angles are retired.

  4. Web and SaaS

    CAC payback

    The number we steer by

    Web apps and SaaS on search and paid social

    Acquisition cost tracked from the first click to the paid plan, and judged on how quickly it pays back.

What we run

ScopeThree disciplines, one accountable team. Nothing is passed between vendors.

The ads, the campaigns, the proof: performance marketing under one roof

For CMOs and founders who want the ads, the media and the measurement handled by one accountable team, not three vendors pointing at each other.

01

Paid media

Paid media and user acquisition

We run your campaigns end to end: strategy, builds, bids and budgets, with reporting against your MMP data rather than screenshots.

Measurement

Tracking, attribution and incrementality

Campaigns are only as good as the numbers steering them. We set up and audit MMPs such as AppsFlyer and Adjust, map SKAN conversion values on iOS, and run incrementality tests when attribution alone cannot answer the question.

How an engagement runs

Research, create, buy, learn

  1. 01 · Research

    Where the money actually is

    We start in your account and your store or site, not in a template: which audiences already convert, which creative angles are worn out, what the category is bidding.

    • Account, store listing and site data
    • Creative angles already saturated
    • Category and competitor bidding
  2. 02 · Create

    A batch, not a one-off

    Creative is made in batches of 20 to 80 finished ads, from €363 each, so there is enough variation to learn something rather than one hero asset to defend.

    • Video, UGC and AI-generated concepts
    • 20 to 80 finished ads per batch
    • Built for the placements you actually buy
  3. 03 · Buy

    One team on every channel

    The people who briefed the creative run the spend across Google, Meta, TikTok, Apple Ads, Snapchat, Moloco and ChatGPT Ads. Nothing is handed over a wall.

    • Google, Meta, TikTok, Apple Ads, Snapchat
    • Moloco and ChatGPT Ads

    The result decides the next batch

    What returned tells us what to make next. Every review runs on SKAN and MMP numbers, so the next batch is briefed from evidence, not opinion.

    • Spend and attribution visible to you
    • Winning angles briefed back into creative
    • No black boxes, no hidden rebates

About Trosmere

How we workFour principles, applied to every account we run.

Growth is a creative problem before it is a media problem.

Trosmere is a performance marketing agency for fast-scaling apps, games and ecommerce brands. The agency is fully remote and distributed across time zones, and the person you speak to is the person doing the work.

We start from the ad, because the ad decides whether spend can scale. Media buying and measurement then decide how far and how fast it goes, and you see every number we use to make that call.

  1. 01

    Creative leads, media scales it

    Creative decides whether a campaign scales, so every engagement starts from the ad. Our media buyers and measurement decide how far and how fast it goes.

  2. 02

    Operators over vendors

    Everyone on the team has run a channel in production. You talk to the person doing the work.

  3. 03

    Transparency by default

    You see the spend, the MMP data, the attribution logic and the incrementality tests behind every decision. No black boxes.

  4. 04

    Share the playbook

    You get the reasoning, the test plans and the learnings, written down.

Platforms and stack

Frequently asked questions

01What does Trosmere actually do?

Trosmere is a performance marketing agency for apps, games and ecommerce brands. We handle performance marketing and user acquisition end to end: we produce the ad creative, including AI-generated video and UGC, run the media buying on the same team across Google, Meta, TikTok, Apple Ads, Snapchat, Moloco and ChatGPT Ads, and then report on what the spend returned.

02How is creative priced?

Creative is made in batches of 20 to 80 finished ads, from €363 per finished video ad, so there is enough variation to learn something rather than one hero asset to defend. The batch planner gives an indicative figure for any size of batch.

03Which platforms do you run?

Google, Meta, TikTok, Apple Ads, Snapchat, Moloco and ChatGPT Ads, all run by the same team that briefs the creative, so nothing is handed over a wall.

04What is the AI Creative Factory?

The AI Creative Factory is Trosmere’s own AI creative production line. A strategist develops the idea, AI generates the video, and our team edits, subtitles and colour-grades every ad before it ships. Ads ship in batches of 20 to 80 finished ads, from €363 each.

05Do you produce the creative or just buy the media?

Both, and deliberately on one team. We produce video, UGC and AI-generated ad creative in batches of 20 to 80 finished ads, from €363 per ad, and the media buyers running your account decide what is made next based on what the last batch returned.

06What is your approach to tracking and attribution?

We treat measurement as a discipline in its own right. Your MMP, whether AppsFlyer or Adjust, is set up and audited so the data can be trusted; SKAN conversion values are mapped to the events that predict revenue on iOS; and when attribution alone cannot answer a question, we run incrementality tests. You see the same dashboards we do.

07Who runs my account day to day?

Operators, not account managers. Everyone at Trosmere has run a channel in production, so the person you speak to is the person making the changes. You see the spend, the attribution and the reasoning behind every decision.

08What size of advertiser do you work with?

Ambitious, fast-scaling apps, games and ecommerce brands that already have a product in market and budget behind it. Usually we work with the CMO, the founder or the growth lead. That includes mobile app marketing, user acquisition for mobile games and app store optimisation.
