Piotr Litwa is an independent Web Analytics and GTM expert service based in Poland. Its core promise is to keep a company’s Google Tag Manager and GA4 setup continuously functional and data-accurate. It is not a standard SaaS tool, but rather a marketing data operations service built around expert monthly monitoring, configuration fixes, and written reports. It targets European businesses, especially ecommerce, retail, SaaS, and technical teams.
The service is divided into four categories: GTM monitoring, GA4 monitoring, agency audits, and custom development. The GTM service checks tags, triggers, variables, the data layer, and Consent Mode v2 every week. The GA4 service verifies events, conversion goals, custom dimensions, and attribution on a monthly basis. Agency audits cross-check ad platform reports against GA4 and tracking data to assess conversion attribution and budget efficiency. Data mainly comes from client-authorized access to GTM, GA4, and advertising reports such as Google Ads and Meta. Read-only access is usually sufficient.
Pricing is relatively transparent: GTM Starter is €150/month, the GTM+GA4 Bundle is €250/month, Full Monitoring starts from €400/month, and agency audits cost 3% of ad spend with a minimum of €200/month. Consulting for Adobe, PowerBI, Looker, BigQuery, Python, R, and related tools is €80/hour. Subscriptions are billed monthly, can be canceled at any time, and have no minimum term. Pricing is in EUR, with billing handled by Stripe.
The main advantage is its highly focused positioning, making it well suited to solving the common marketing data problem of “tracking is broken but nobody notices.” Asynchronous delivery and monthly written reports reduce meeting overhead, while the service also covers Google, Adobe, and data engineering stacks. The downsides are also clear: this is an individual expert service, and its ability to deliver at scale or provide team backup is not specified. There is no clear SLA or real-time customer support, annual billing is not currently supported, and only EUR is accepted.
It is best suited for companies that rely on GA4 for advertising, conversion tracking, and product decisions, as well as teams spending more than €5,000 per month on ads and looking for an independent review of agency reports. If you only need a one-time GA4 setup, a local agency or freelance consultant may be more flexible. If you need ongoing data quality monitoring, the fit is stronger.
The site does not disclose performance or accessibility from mainland China, so this remains unknown. Payments are processed via Stripe in EUR, which may create currency, invoicing, and cross-border payment barriers for Chinese companies. Alternatives include local GA4/GTM consultants, digital marketing agencies, internal BI teams, or building your own monitoring workflow with GA4, Looker Studio, and BigQuery.
