E-commerce. Digital. Now AI.

Since 2014 I have run e-commerce and online marketing for brands all of Poland knows: Groupon, DOZ.pl, Trec Nutrition. Since 2023 I design and ship AI: audits, custom systems, ads and 3D graphics.

A time of change.

There has never been a change like this one.

“The technological progress we make in the next 100 years will be far larger than all we’ve made since we first controlled fire and invented the wheel.”
Sam Altman, CEO of OpenAI · “Moore’s Law for Everything”, 16 March 2021

Nobody knows what the future will look like. So you have to create it yourself.

We are groping our way towards the biggest change in the history of the world, hoping it will somehow work out.

♫ Mega Dance – “Coca Cola” · from 0:50
“It’s going to be 10 times bigger than the Industrial Revolution, and maybe 10 times faster.”
Demis Hassabis, 2024 Nobel laureate in Chemistry, CEO of Google DeepMind · The Guardian, 4 August 2025

But surely the last one.

Michał Mieszko Lis

Change is an opportunity, not a threat.

  1. GrouponWeb analytics was only taking shape: we defined metrics like CTR, OR and lifetime value ourselves, and the cookie window was 30 days. I learnt that whoever measures every week sees the opportunity first.
  2. DOZ.plAdvertising under an advertising ban? A promotion without mentioning the price cut? A coupon without a discount? 26,000 SKUs? We turned every constraint into turnover: the app, the largest SALESmanago implementation in Poland and the largest affiliate programme in Poland, built from scratch in 6 months. Turnover ×2.
  3. Trec4 new product lines, a new approach to PPC and a strategic, direct partnership with Google. Quality, not price. Brand, not promotion. Ownership of the whole brand online. Result: store turnover +220%.
  4. AINow everything changes at once. I show companies how to turn this change into an edge before their competitors do, while an edge can still be defined by something other than tokens.

Specialism · pharmaceutical law and advertising of medicines and supplements in practice

Both sides of the shelf.

I know pharmaceutical law and the advertising of medicines and dietary supplements from both sides: as a manufacturer and as a pharmacy. Few people in Poland have this experience, and it decides whether a campaign sells or ends in a fine.

Manufacturer

Trec Nutrition, Aflofarm group

Dietary supplements and sports food: notification to the Chief Sanitary Inspectorate, authorised health claims (Regulation 1924/2006), novel food, labels and ads with no medicinal promises, work with ambassadors.

Pharmacy

DOZ.pl, the Pelion Group online pharmacy

Online pharmacy: the ban on pharmacy advertising (art. 94a of the Polish Pharmaceutical Law), mail order of OTC drugs only, prescription drug reservations, e-prescriptions, medical devices and dermocosmetics, manufacturer-funded budgets.

The Polish pharmacy market: how it works

The market where I ran DOZ.pl marketing for almost 4 years. Legal status: October 2026.

12,267Pharmacies

pharmacies and pharmacy points at the end of 2025 (Ministry of Health data); the number has been falling since 2017. Since the “Pharmacy for Pharmacists” amendment, a new pharmacy can only be opened by a pharmacist or a pharmacists’ partnership, at least 500 m from the nearest one and for at least 3,000 residents of the municipality.

discountRewards for purchases

Discounts, gifts or points for buying in a particular pharmacy are treated by the pharmaceutical inspectorate as banned pharmacy advertising, and the new law bans them outright. That is why dermocosmetics and supplements must be kept apart from OTC drugs: they can be on promotion, while a medicine may only be advertised by its marketing authorisation holder.

art. 94aPharmacy advertising ban

Since 2012 a pharmacy may only state its address and opening hours. The word “promotion” alone could bring a fine of up to PLN 50k from the regional pharmaceutical inspector (a manufacturer’s promotion printed on the pack was an exception). DOZ.pl was the most inspected pharmacy in Poland, and I grew the affiliate programme so that publishers took over responsibility for the ad content. In 2025 the CJEU (C-200/24) ruled the total ban incompatible with EU law.

PLN 1MNew rules

The Sejm voted to lift the ban on 18 Sep 2026 and the Senate added amendments on 13 Oct 2026. Pharmacy advertising returns, but with no rewards for purchases, no comparisons, no celebrities and no people with medical training. Fines of up to PLN 1M per pharmacy.

SmPCOTC drug advertising

Only the marketing authorisation holder, or someone it commissions, may run it, in line with the summary of product characteristics and with the mandatory “This is a medicine…” warning. Prescription and reimbursed drugs may not be advertised to the public. The Chief Pharmaceutical Inspector orders ads stopped and corrected, and unlawful advertising carries a fine.

PLN 2MMedical devices

Since 2023 advertising falls under the Medical Devices Act, supervised by the President of URPL. Fines of up to PLN 2M, up to PLN 5M for misleading claims.

GDPRHealth data

A pharmacy’s sales data is in practice health data: purchase history of medicines reveals conditions, so it falls under special protection (Art. 9 GDPR). Segmentation, marketing automation and remarketing have to be designed with that in mind.

art. 35Pharmacists and sales

A pharmacist decides independently, guided only by the patient’s good (Pharmacist Profession Act), and the pharmacy owner must guarantee it. Manufacturers may not reward dispensing their products, and reimbursed drugs carry official prices and pharmacy margins.

copyProduct page

In a pharmacy you speak to a patient, not a customer. An online pharmacy’s drug description is judged like an ad: only what the SmPC and leaflet say. Supplements: only authorised health claims (rules below). A dermocosmetic may not promise treatment.

Health claims: how they work

A food supplement is food, not medicine: it is notified to the Chief Sanitary Inspectorate before launch. Every sentence about what a supplement, sports food or other food does, on the label, in the product description and in ads, falls under Regulation (EC) 1924/2006 and the EU list of claims (Regulation 432/2012). Supervision: the State Sanitary Inspection; successive draft amendments plan supplement ads without doctors and pharmacists.

  1. Only from the EU list

    Only claims authorised in the EU register may be used. The wording can follow the brand’s voice, but the meaning for the consumer must stay the same, with no stronger promise.

  2. Conditions of use

    Every claim has a threshold. Creatine: “Creatine increases physical performance in successive bursts of short-term, high intensity exercise” only at 3 g a day, with the consumer told about that dose. Protein: “Protein contributes to a growth in muscle mass” only if the product is at least a source of protein. Vitamins and minerals: a significant amount, as a rule at least 15% of the reference intake.

  3. General wording

    “Supports immunity”, “for your health” and similar general benefits are allowed only next to a specific authorised claim (Art. 10(3)).

  4. Mandatory notes

    With a claim on the label: the importance of a varied diet and healthy lifestyle, the quantity and pattern of consumption needed for the effect, a warning for people who should avoid the product, and a warning against excessive intake (Art. 10(2)).

  5. No cures

    Food, supplements included, may not claim to prevent, treat or cure a disease (Regulation 1169/2011). Disease risk reduction and children’s development claims come only from a separate list (Art. 14).

  6. Botanicals “on hold”

    Claims for plant ingredients are still awaiting EU assessment and rely on transitional rules. The CJEU (C-386/23, 30 Apr 2025) confirmed that a claim outside the lists may not be used in ads or product presentation unless the transitional period protects it. According to the Polish Chief Sanitary Inspectorate, being on the “pending” list is necessary but not sufficient: the manufacturer must hold the scientific evidence.

I know the products from the inside: proteins, creatines, pre-workouts, electrolytes and gels for endurance sports, sportswear; OTC and Rx drugs, medical devices, dermocosmetics and supplements.

From e-commerce to AI.

Since 2023 I build myself what I used to order from agencies: websites, ads, 3D graphics and tools. Faster and cheaper with AI, with the same discipline on results, budgets and law.

We automate the business.We scale creative with no ceiling.Execution runs itself.

How I work: ADHD invents, AI executes, autism rationalises. On top of that I understand how AI thinks and get along with it better than most people. That is my edge.

What I do now

AI audit

Where AI pays off in your company, what it costs in tokens and licences, what the risks are. A report with a roll-out plan.

AI and the law

Team AI-use policy, the EU AI Act, GDPR, copyright, labelling AI content, advertising rules for supplements, OTC drugs and medical devices.

Implementations

AI agents, automations, RAG over company documents, assistants for sales, marketing and support teams.

Custom software

CRMs, dashboards, AI cost panels, internal tools: from mock-up to a working system in days, not months.

AI ads

AI video, voice-over, motion design, beat-cut editing; 16:9 and 9:16 cuts for campaigns.

Websites and 3D

WebGL websites, visualisations, Blender fly-throughs, Unreal Engine walkthroughs.

For over 2 years I had the pleasure of working with Michał in one group. As an e-commerce manager Michał has all the key qualities: responsiveness, a positive attitude, 100% commitment. His performance marketing skills, and the way he grows that knowledge and shares it with others, are second to none. What sets Michał apart is his exceptional analytical thinking and the way he inspires people. He also adapts easily to any situation and business dynamic. Any team would be lucky to have Michał; I can recommend him to any company looking for new talent.

I have been working with Michał for over 7 months now and since then his commitment, dedication to work and at the same time the passion he puts into it is unimaginable. I always got along well with Michał during these 7 months, and the effects of our cooperation were reflected in the achieved targets for projects in which we had the opportunity to participate. Michał always approached all tasks analytically and meticulously, thanks to which I was sure that everything would be done. I can confidently recommend Michał as a good leader and partner for cooperation in digital and brand projects.
