Zest Agency

Zest started from a frustration we kept seeing on both sides of the industry: creative agencies made things that looked great but rarely moved revenue, and performance agencies pushed ad budgets into channels without knowing whether the creative, the offer, or the tracking behind it was actually working. Every project got stuck in the handoff between the people who made the ad and the people who bought the media, and clients paid for that gap.

So we built Zest around one rule: performance, analytics, and creative live under one roof, on one team, working off the same numbers. Before we scale a single dollar of ad spend, we set up bulletproof tracking — a custom dashboard blending ad spend, CRM and real revenue data, built on our own tracking pixel instead of platform-reported numbers that rarely agree with each other. Clients own that data outright from day one, no lock-in.

AI runs through everything we build, not as a buzzword but as leverage: we use it to accelerate engineering on website builds, to produce AI-generated video, animation and creative variants at a speed no studio production can match, and to automate research and reporting so our team spends time on strategy instead of manual work. That same instinct led us to build Loyalz, our own loyalty, social activation and creative-analytics platform for e-commerce and DTC brands doing 500k+ PLN a month — turning one-time buyers into repeat customers instead of just chasing the next acquisition campaign.

That discipline is why our promise is simple: performance you can see in your P&L. We don't optimize for reach or likes; we optimize for margin, and we make sure clients can verify that math themselves. Every week, a real person, not an automated report, walks clients through results and takes accountability for the outcome.

Today we work with B2B and e-commerce brands from early-stage startups to enterprise clients, running paid media, website and e-commerce builds, UGC content production, and analytics implementations as one connected system. Our clients have grown revenue by an average of 30.7% within 6 months, and we generated 5.24M PLN in tracked client revenue over the past year. That's the story we're still writing — one campaign, one dashboard, and one AI-accelerated workflow at a time.
