Stop Renting Your Most Critical Asset

We transform your raw data into a clear, controllable competitive advantage.
Is Your Growth Built on a Foundation of Sand?
Your daily reality is a frustrating cycle of conflicting reports and wasted ad spend. You're making strategic decisions based on data you can't trust. This isn't just a technical problem—it's a direct threat to your profitability and growth.
Conflicting Truths, Wasted Spend
Your ad platforms, Shopify, and GA4 all report different numbers. You're burning cash on ad spend because you have no way of knowing which channels *actually* drive profitable growth.
Your Data, Held Hostage
Your most valuable asset—your customer data—is trapped inside third-party tools. You can't access the raw details, export it freely, or use it for advanced modeling.
Brittle, Outdated Tracking
Your current setup feels like a house of cards. With every browser update or privacy change, your data breaks, leaving you blind and vulnerable to future shocks.
Surface-Level Insights
Standard reports only show you what happened, not why. You're stuck with sampled data and can't answer deeper questions about customer lifetime value or complex user journeys.
Mounting Technical Debt
Patchwork solutions and quick fixes have created a complex, unmanageable mess. It's slow, prone to errors, and requires constant developer time to maintain.
Strategic Paralysis
You have ambitious growth plans but hesitate to commit. The lack of a trustworthy data foundation makes every major investment feel like a high-stakes gamble.
The True Cost of Inaction is Compounding
It's not just the money you waste today. It's the compounding effect of misallocated capital, the strategic opportunities you miss, and the permanent loss of invaluable customer data you can never get back.

We don't deliver temporary reports; we build you a permanent analytics asset. This end-to-end system gives you absolute control over your data, from collection to your own BigQuery warehouse, so you can finally scale with confidence.

I Got Tired of Bad Data,So I Built a Better Way
I'm Sascha Herpertz. After years of seeing founders burn money on ads because of faulty data, I decided to fix the problem myself. Mercareo was built to give business owners what I always wanted: data that is undeniable and infrastructure that is a permanent asset.
"I saw that 'good enough' tracking was a lie that cost businesses money. My mission became to build analytics systems that deliver undeniable truth, empowering founders to make confident, profitable decisions."
The Problem: Wasted Ad Spend
I saw countless businesses pouring money into ads, only to be betrayed by flawed tracking. I became obsessed with fixing the root cause of this data inaccuracy, not just applying temporary patches.
The Obstacle: Constant Chaos
The digital world is designed to be confusing—iOS updates, server-side tracking, privacy laws. I dedicated myself to mastering this chaos to build systems that are resilient by design.
