I started with code. While studying computer science at the Jagiellonian University, I wrote websites and apps, and then spent years building online stores for others. Today I run an agency that does both: it builds stores and scales them with marketing. I am the co-founder and CEO of Surf Inc., and I also run my own businesses: PeppeShoes, Perfect Cup and Sauna & Spa Store. I am responsible for their sales and brand image, so every mistake costs me as much as it would cost you. We are a certified Google and Meta partner, and PrestaShop has given us Expert ★★★ status, the highest level the platform awards to agencies. We are based in Kraków, and when you sell abroad, you have our business manager on the ground, in your market's time zone. Write to me and I will tell you what I would do with your store. ![Signature: Mateusz Haber](https://justidea.agency/obrazy/logo-f717444f.svg) Mateusz Haber CEO, JustIdea Agency Mateusz's awards ![Dyrektor Marketingu Roku 2024](https://justidea.agency/obrazy/dyrektor-marketingu-2025-3b18bc0e.png) ![Dyrektor E-Commerce Roku 2024](https://justidea.agency/obrazy/dyrektor-ecommerce-2024-99eb738f.webp) ![Odkrycie Roku 2024](https://justidea.agency/obrazy/odkrycie-roku-2024-b96cf107.webp) ![semKRK Awards 2024](https://justidea.agency/obrazy/semkrkawards2024-1-pl-a2011fee.webp) ![semKRK Awards 2026](https://justidea.agency/obrazy/semkrkawards2026-ecomm-1-300x82-e4d04e66.webp) ![Performance Marketing Diamonds EU 2025](https://justidea.agency/obrazy/pmd-logo-removebg-preview-e1668079366104-6dbefba7.webp) [All awards and certified partnerships](https://justidea.agency/en/our-awards/) Proof ## Our work, case studies and awards [### Our work Brands we have worked for, listed by name, each with its logo and the scope of our work.

When something breaks, you know who is responsible. ### We count profit, not ROAS We set up measurement so that the report shows the margin after ad costs, that is the money that stays in your business. ### We check budget and timeline before we start If a project will not fit your budget or timeline, you will hear it in the first conversation, before the contract is signed. How we are organised ## Four departments, each with a lead You see the tasks of all four departments in one project. On top of that there is a two-person management board. ### Development and e-commerce 5 people PrestaShop implementations and migrations, modules, integrations with ERP, WMS and payment systems. ### Performance and automation 7 people Google Ads, Meta Ads, shopping campaigns and lifecycle flows. We manage a budget of €3.2M a year. ### SEO and AI visibility 3 people Store SEO, technical SEO, content and presence in the answers of large language models. ### New business and account management 4 people Quotes, project management and contact that does not end once the contract is signed. Team ## 21 people on the team We run projects ourselves, without subcontractors. ### Management 2 people ![Mateusz Haber](https://justidea.agency/obrazy/mateuszhab-ea59408f.webp) Mateusz Haber CEO / Marketing & E-Commerce Specialist ![Paweł Dębosz](https://justidea.agency/obrazy/paweld-9e2fac62.webp) Paweł Dębosz Chief Operating Officer ### Development 5 people ![Mateusz Olszański](https://justidea.agency/obrazy/mateuszo-98716864.webp) Mateusz Olszański Team Leader Web Developer ![Anna Kołcon](https://justidea.agency/obrazy/ania-scaled-7880bedd.webp) Anna Kołcon Project Manager Web Developer ![Arkadiusz Pabisz](https://justidea.agency/obrazy/arek-dbe2094e.webp) Arkadiusz Pabisz Web Developer ![Kewin Bielecki](https://justidea.agency/obrazy/kewin-bielecki-13dffe52.webp) Kewin Bielecki Web Developer ![Karol Żelazny](https://justidea.agency/obrazy/karol-zelazny-8eb010e0.webp) Karol Żelazny Web Developer ### Performance and marketing 7 people ![Grzegorz Fedrych](https://justidea.agency/obrazy/grzegorz-fedrych-1905b692.png) Grzegorz Fedrych Digital Marketing Team Leader ![Malwina Jurga](https://justidea.agency/obrazy/malwina-jurga-ca5fdd10.webp) Malwina Jurga Digital Marketing Project Manager ![Paweł Śliz](https://justidea.agency/obrazy/pawel-sliz-06404ee8.webp) Paweł Śliz Performance Marketing Specialist ![Mateusz Barczyk](https://justidea.agency/obrazy/mateuszba-1289b187.webp) Mateusz Barczyk Performance Marketing Specialist ![Aleksandra Skotnicka](https://justidea.agency/obrazy/ola-8d97a32e.webp) Aleksandra Skotnicka Marketing Automation Specialist ![Wiktoria Władarz](https://justidea.agency/obrazy/wiktoria-wladarz-e1767793660464-7c4ecd3a.webp) Wiktoria Władarz Marketing Communications Specialist ![Anna Boiko](https://justidea.agency/obrazy/anna-boiko-89ce61df.webp) Anna Boiko Performance Marketing Specialist ### SEO 3 people ![Małgorzata Walo](https://justidea.agency/obrazy/gosia-f6dce947.webp) Małgorzata Walo Team Leader SEO ![Wojciech Wabno](https://justidea.agency/obrazy/wojtek-scaled-5d5ce955.webp) Wojciech Wabno SEO Specialist ![Kalina Mądry](https://justidea.agency/obrazy/kalina-madry-b9d3c575.webp) Kalina Mądry SEO Specialist ### New business and office 4 people ![Marcin Kądziela](https://justidea.agency/obrazy/marcin-kadziela-58892641.webp) Marcin Kądziela Head of Sales ![Paweł Koszałka](https://justidea.agency/obrazy/pawel-koszalka-f573fca5.webp) Paweł Koszałka New Business Specialist ![Martyna Iskra](https://justidea.agency/obrazy/martyna-iskra-40be4bb4.webp) Martyna Iskra New Business Specialist ![Marzena Stupkiewicz](https://justidea.agency/obrazy/marzena-scaled-aaae39f2.webp) Marzena Stupkiewicz Executive Assistant ![An empty seat on the team](https://justidea.agency/obrazy/youarenext-cd112442.webp) ### This seat could be yours We have three open positions.
