Dawid Strzelecki

Creative strategy for retail and e-commerce brands. From brand concept to the number at the end of the month.

Four years in retail and e-commerce marketing. I started at CCC on brand communication, then EssenceMediacom media agency running nine markets at once, now MODIVO.

I run HalfPrice's TikTok, plan paid campaigns, and make sure what we came up with in the deck can actually get shot.

Psychology at SWPS, management at WSB Merito.

01 MODIVO PERFORMANCE + UGC

Selling a subscription on a budget with no slack

MODIVOclub Gold is a program the customer pays for upfront. A harder sell than a product — you have to convince someone to buy a subscription in a shoe store.

ROLECo-led the project, from concept to reconciliation
CHANNELSMeta, Google, TikTok
PERIOD02.2026 - 05.2026

STARTING POINT

The program had real benefits, but the messaging talked about what it was, not what the customer got out of it. On top of that, a budget with no room for blind testing.

With a subscription, the cost of a mistake is higher than with a regular sale. One bad message burns traffic across the whole funnel, not just one creative.

WHAT I DID

  • Benefit-led messaging. Instead of describing the program itself, we showed how much the customer saves and what they get.
  • Funnel architecture. Each stage got its own function and its own creative type.
  • Creator and influencer selection. I picked people for the segment, not for reach.
  • Briefs and content control. I checked every piece before it went live, because a fix after launch costs more than a day's delay.
  • Audience exclusions. We cut people who'd already bought, so we didn't pay twice for the same person.
  • Budget analysis and reconciliation. Results went back to the team as a list of changes for the next batch of creative.

DECISIONS THAT MOVED THE NEEDLE

  • We bet on UGC. Creator-led format outperformed branded production in-feed and cost a fraction of a shoot.
  • Exclusions as a priority, not an afterthought. On a subscription, retargeting buyers is pure budget waste.
  • One benefit per creative. Materials that tried to say everything performed worst and got cut first.

02 LATEST PROJECT SHOCKPRICE CREATIVE STRATEGY + LAUNCH

A new brand that had to show up from zero

ShockPrice launched with no history, no community, and not a single post. I co-created the brand concept, then took ownership of the entire digital side: direction, channel build, and everything that appeared on them.

ROLECo-creator of the brand concept, digital owner
SCOPEBrand concept, channels, creative, activation, paid
PERIOD June 2026 - Present

STARTING POINT

The brand existed on paper. No tone, no formats, no reason for anyone to follow it. On top of that, a store opening date — a date that couldn't move.

With a start like that, the biggest risk is a brand that looks like a cheaper version of something already on the market. It needed its own character and its own language before a single złoty went into ads.

WHAT I DID

  • Brand concept. Co-created who ShockPrice is and how it talks.
  • Shocky the mascot. Built a campaign series around it, including the "American Dream" chapter, so the brand had a face from day one.
  • Launch activation plan. A lead-capture layer in digital, a social rollout, a list of influencers to invite.
  • Creative production. UGC scripts and image-generation prompts, to fill the calendar without waiting on a photoshoot.
  • Catalog tool. An HTML product catalog built from PDF and PPTX files, so no one had to retype the assortment by hand.
  • Post-launch digital direction. Decisions on which channels grow, what goes to paid, and what stays organic.

DECISIONS THAT MOVED THE NEEDLE

  • A mascot instead of models. A new brand with no recognition needs something that sticks after one scroll. A character does that cheaper and faster than a photoshoot.
  • AI creative from day one. I built a prompt library, so production never became a bottleneck. The calendar filled up in a week, not a month.
  • Capturing contacts before opening. The capture layer went live before the store did, so day one didn't start from an empty database.

03 HALFPRICE CREATIVE STRATEGY / SHORT-FORM

A channel that sounds like a person, not a retail chain

I run HalfPrice's TikTok on the creative side. I set direction, come up with formats, write scripts and hooks, and make sure what we come up with can actually be shot without a film crew.

ROLEChannel lead, creative direction
SCOPEFormats, scripts, hooks, copy, production oversight
PERIOD2.2026 - 6.2026

STARTING POINT

An off-price brand has an identity problem on TikTok. Too cheap to play aspiration, too much assortment to talk about one product.

On top of that, a team that started from zero and guessed the tone on every video. The channel needed rules to fall back on, so every piece of content didn't restart the same debate.

WHAT I DID

  • 15 audience segments with archetypes. Perfect Madam, Weekend Swagger, Diva, and the rest. Actual characters you can write a script for, not a "women 18–34" bracket.
  • Channel tone of voice. Boiled down to one line the team remembers: Ryanair's body, Rhode's soul.
  • Faceless formats. Series that can be shot on a phone in-store, with no creator on camera.
  • Scripts and hooks. I write them so the editor knows exactly what to do, without an extra call.
  • Production oversight. From idea to publish — I shoot part of the material myself.

DECISIONS THAT MOVED THE NEEDLE

  • Formats you can repeat. A series you can shoot twenty times is worth more than one great video shot once.
  • Archetypes instead of demographics. A script for a specific character takes fifteen minutes to write. A script for an age bracket doesn't get written at all.
  • Faceless as the backbone, creators as the extra. The channel stopped depending on who happened to be free to step in front of a camera.

Four brands at once, each with a different voice

Creative strategy and channel management for four brands from one group. Each has a different audience, a different reason to exist, and a different tone — run by the same team, on the same trade calendar.

ROLECreative strategy and channel management
SCOPEMessaging angles, publishing plans, calendar, automation
CHANNELSFacebook, Instagram, TikTok

STARTING POINT

Four brands in one group easily start sounding the same. Same team, same tools, same sale calendar. It takes a few months before you could paste one brand's post onto another's profile and no one would notice.

Sprandi, Jenny Fairy, HalfPrice, and ShockPrice sell different things to different people. If they speak with one voice, none of them has their own, and the group pays four times for the same effect.

WHAT I DID

  • A separate creative strategy per brand. Messaging angles, audience archetypes, and tone matched to who the brand actually sells to.
  • Split content territories. Each brand got topics the others don't touch, so they stopped stepping on each other.
  • Monthly publishing plans. Broken down by goal, format, and moment in the trade calendar, separately for each brand.
  • One multi-channel calendar. Facebook, Instagram, and TikTok in one place, so overlaps were visible.
  • Organic and paid alignment. Content planned so the best posts could be backed with budget right away.
  • Message automation. Rolled out ManyChat to handle DMs on MODIVO's Instagram, for repeat questions about availability and returns.

DECISIONS THAT MOVED THE NEEDLE

  • Strategy per brand, shared operations. Each brand's voice is separate, but the calendar, formats, and production process are one. Otherwise either everything sounds the same, or the team can't keep up.
  • Concrete content territories. Nobody opens a tone-of-voice document. A list of topics assigned to a brand works immediately when planning the month.
  • Automation only for repeat questions. The bot doesn't carry a conversation — it answers what a human would answer thirty times a day anyway.

05 MR.DIY POLAND · HALFPRICE COMPETITIVE INTELLIGENCE

What the competition does, broken down

Two full audits in the same framework: brand, social media, paid, and TikTok. Not an opinion on whether someone else's ads look nice — a classification of what they run, and a map of what they don't.

ROLEAudit author
SCOPEBrand, social, paid, TikTok
BRANDSMR.DIY Poland, HalfPrice

STARTING POINT

Creative decisions in retail often get made by gut feel, because no one has time to review two hundred of someone else's ads. The result is half the category doing the same thing and no one noticing.

An audit only makes sense if it ends in a list of things to do. A description of the competition on its own is a curiosity.

WHAT I DID

  • Breakdown of creative from ad libraries. Each one classified by messaging angle, mechanic, hook type, and format.
  • Social media presence audit. Formats, frequency, tone, and how the channel is run.
  • Paid activity analysis. What they promote, how long each creative runs, who it's targeting.
  • A separate TikTok layer. Because different rules apply there than on the rest of the channels.
  • Gap map. Spots no one in the category covers, turned into concrete topics to act on.

DECISIONS THAT MOVED THE NEEDLE

  • Classification instead of description. The sentence "they run a lot of UGC" gives you nothing. A table showing most of their creative hits one angle tells you exactly what to do.
  • A gap map, not a ranking. An audit isn't there to decide who's better — just to point at open space.
  • The same framework for both brands. Results become comparable, and auditing the next brand takes a day, not a week.

Tools the whole team works from

Planning and reporting for paid campaigns across several markets. Less flashy than creative, but without it nobody knows what worked and why.

ROLESystem author, daily user
SCOPEMulti-market plan, naming, reporting, benchmarks
SCALE5 roles on the team, 15 markets

STARTING POINT

Campaigns across several markets, five people on the team, and campaign names everyone set up their own way. Putting together one report ate a whole day and ended in a debate about whether the numbers were even comparable.

I once mixed up the translation folders for Lithuania and Latvia myself. It surfaced when the local team received it, we fixed it the same day, and the naming convention and per-market checklists came directly out of that mistake.

WHAT I DID

  • Multi-market plan in Excel. 14 sheets, five roles, one shared place — not five versions of the same file in five inboxes.
  • Naming convention. Shared across Meta and TikTok, so the report builds itself.
  • Automated sponsored-post report. With a rule that missing data gets flagged explicitly, not entered as zero.
  • CPM benchmarks and reach modeling. You know what reach should cost before a campaign even launches.
  • Year-over-year comparisons. The impact of budget changes on results, in a form you can show to leadership.

DECISIONS THAT MOVED THE NEEDLE

  • Naming before automation. Without a shared convention, no report calculates itself.
  • Flagging gaps instead of zeroing them out. A zero in a report lies. A note about missing data tells the truth and protects you from a bad call.
  • One file for the whole team. Five copies means five different truths in the status meeting.
