In ROI we trust

We are a performance marketing agency and production house based in Poland.

We build digital growth as one connected system — performance media, creative production, and analytics under a single team — rather than as separate vendor line items. Every engagement is built around one measurable outcome: performance you can see in your client's P&L, not just in-platform metrics.

Our Story

Zest was built to close the gap between agencies that make things look good and agencies that spend budget well — we own performance, analytics, and creative under one roof. Our rule: bulletproof analytics before we scale spend, full data ownership for clients, and weekly, human accountability for results. As official Google and Meta partners, we've driven an average 30.7% revenue growth for clients in 6 months — performance you can actually see in your P&L.

What Sets Us Apart

Performance, Analytics & Creative in One Team

We run performance, analytics, and creative under one roof, no vendor handoffs. Every campaign launches on a custom dashboard built on real revenue data, not platform guesses, so results show up where it counts: your P&L, not vanity metrics.

You Own Your Data, No Exceptions

Every client gets a custom dashboard blending ad spend, CRM and real revenue, built on a proprietary tracking pixel, not platform-reported numbers. You own it outright from day one, license-free, so nothing disappears if we ever part ways.

Real Accountability, Every Week

No automated PDFs. A real person walks you through results every week and owns the outcome, good or bad. We only scale ad spend once tracking is proven solid, so growth is predictable, not a lucky spike.

Commonly Asked Questions

We start with a free discovery call and a quick audit of your accounts, site, and past data, and turn around a proposal within 48 hours — no long sales cycle. Once you're in, onboarding runs as a fixed process, not paperwork: Brief & Audit — we map your business goals, existing campaign data, tech stack, and competitors, so strategy is grounded in your actual numbers, not templates. Analytics Foundation — before a single dollar of ad spend, we set up bulletproof tracking (GA4, server-side GTM, a dedicated dashboard blending ad spend, CRM and revenue). You own this data from day one. Creative & Campaign Build — our in-house team builds the first batch of creative and campaign structures around what the audit shows actually converts for your audience. Launch, Test & Scale — we launch with a testing mindset to find the winning creative and channel mix, then scale spend behind what works. From there you get weekly, human check-ins — a real person walking you through results and owning the outcome, not an automated report. Most clients go from first call to live campaigns within 1–2 weeks.

We're most excited about growth-stage B2B and e-commerce brands that already have some traction — a working product, some customer data, maybe an existing site or ad account — and want to scale performance marketing on solid analytics rather than guesswork. Full-funnel engagements are our sweet spot: paid media (Google, Meta, TikTok, LinkedIn) combined with a proper tracking/dashboard setup and ongoing creative production, rather than one-off campaign bursts. On the web side, we're taking on new site builds and e-commerce launches (React, WordPress, Shopify, WooCommerce) for brands that need something live fast and built to convert, not just look good. We're also actively growing our UGC/creator content work for DTC and e-commerce brands running paid social who need a steady stream of authentic video, and our dashboard/analytics builds for multi-channel sellers who are tired of reconciling numbers across platforms. We're a good fit for clients who want a long-term, accountable partner and are open to sharing real business data — not just ad-platform metrics.

We report on results, not activity — and we do it in person, not through auto-generated PDFs. Every client gets a weekly check-in where a real member of the team walks through what happened, what it cost, and what we're changing next, and takes accountability for the outcome rather than just presenting numbers. Reporting itself runs through a live dashboard, not a static deck: we blend ad spend, CRM data and actual revenue into one view showing real profitability metrics (MER, Blended CAC, LTV/CAC), so you're looking at margin, not vanity metrics like reach or CTR in isolation. You own that dashboard and the underlying data from day one — there's no lock-in and nothing disappears if we ever part ways. Day-to-day, communication happens over whichever channel works for you (email, Slack, Teams), with automated alerts flagging tracking issues or performance anomalies as soon as they happen, rather than waiting for the next scheduled report. For content-heavy engagements like UGC, we also send monthly performance summaries alongside the weekly check-ins.

Every client is assigned a small, dedicated pod rather than being routed through a generalist account manager — typically someone owning performance/media buying, someone owning analytics, and someone owning creative, all working off the same dashboard so decisions aren't made from stale spreadsheets. Work moves in a fixed cadence: strategy and audit first, then a build phase with clear milestones (e.g. a functional dashboard interface within 2 weeks, a simple site or landing page within about a week, full analytics rollout in 3–4 weeks), then a testing phase to find what actually converts before we scale spend behind it. Timelines and scope are set upfront in the 48-hour proposal, so there's no ambiguity about what "done" looks like at each stage. Progress is tracked against the same numbers the client sees — spend, revenue, CAC, conversion rate — not internal task boards, so status updates are always tied to business impact. Any blocker (creative approval, account access, technical dependency) is flagged immediately rather than surfaced at the next scheduled check-in, and the weekly review is where scope, priorities, and next steps get adjusted together with the client.

We don't publish a single blanket "success rate" number, because a fair figure depends heavily on client, budget, and starting point — and we'd rather share real numbers than a marketing stat. Here's what we can point to: clients see an average revenue growth of 30.7% within 6 months of working with us, and we generated 5.24M PLN in tracked client revenue over the past year alone. On the dashboard/analytics side, typical accounts run at a blended MER around 3.84x with Blended CAC brought down to roughly 184 PLN once tracking is fixed and consolidated. At the campaign level, individual case studies show the range: Falcon Car Rental grew Google Ads revenue 74% year-over-year, Gabo Wool grew Meta Ads revenue 152.9% year-over-year, and our UGC/creator content typically lifts CTR by 34%, cuts CPC by 29%, and cuts CPM by 38% versus studio-produced ads. We're also recognized by Clutch as a Top Advertising Company in Warsaw (2023).
