I make sure your data tells the truth.
I'm Piotr Litwa — an independent web analyst and GTM specialist based in Poland, working with businesses across Europe. For over a decade, I've been fixing broken tracking, building reliable analytics infrastructure, and helping companies make decisions based on data that's actually correct.
Why I work the way I work
Most analytics problems I see aren't technical. They're organizational. Someone set up GTM three years ago, nobody checked it since, the agency reports look fine, and everyone assumes the data is correct. It usually isn't.
I started doing independent GTM audits because I kept seeing the same pattern: businesses spending significant budgets on ads, optimizing based on conversion data, and not realizing the conversion tracking had been broken for months. The wasted spend wasn't the worst part — the wrong strategic decisions made from bad data were.
Today I work exclusively on a retainer model — monitoring, not one-off projects. This means I catch problems before they become expensive, not after. And because I work async with monthly reports, clients get the value without the overhead of calls and meetings.

Approach
How I work
Async by default
No standing calls, no weekly check-ins. You get a monthly written report with everything that was checked, found, and fixed. If you want to talk — that's fine, but it's never required.
Transparent and independent
I don't run your ads. I don't build your website. I have no interest in telling you your tracking is fine when it isn't. My only job is accurate data.
Small client base, high attention
I deliberately keep my client roster manageable. Every client gets real attention, not a junior's eyes on a dashboard.
Public speaking
I spoke at WordCamp Poland 2024 about the most destructive GTM mistakes I see in production environments — and how to fix them without breaking everything else. The talk is available on YouTube.
