Zest

Zest is a performance marketing agency and creative production house from Poland. We run paid campaigns on Google Ads, Microsoft Ads, Meta, TikTok, LinkedIn and ChatGPT Ads for e-commerce and B2B companies, and we produce the creatives ourselves: UGC from a network of 200+ verified creators and AI-assisted ad variants.

Every account starts with measurement: GA4, server-side tracking, Consent Mode and offline or phone conversions, so budgets are judged on sales and lead quality rather than clicks. We have been a Google Partner since 2019 and a Meta Business Partner since 2020, and we hold 23 verified reviews on Clutch with an average of 4.9/5. The team is based in the Łódź area and works remotely with clients across Poland, in Polish and English.
