I’m Keijo Mämmi. I help companies build measurement architecture that produces reliable data and supports better decision-making
About Me
My name is Keijo Mämmi. I am an entrepreneur and analytics specialist focused on building measurement systems that support real business decisions. I work primarily with Google Analytics 4, Consent Mode v2, Google Tag Managet (GTM), Looker Studio, attribution, and data quality in privacy-constrained environments. My work starts from one question: what decision needs to be made, and can the data genuinely support it?
I have spent almost three decades as an entrepreneur or company partner. During that time, I have lived through the early-2000s IT bubble, the 2008 financial crisis, and continuous structural change in the business environment. I know what it means to carry responsibility for board-level decisions, sales, and people management while still being directly involved in technology and systems.
My academic background supports this combination. I hold a Master of Business Administration (MBA) in International Business Development and a degree in business administration. However, formal education is only part of the picture. Practical responsibility, risk, and real-world outcomes have shaped how I think and work far more than any single qualification.
I build web services and analytics systems because data has always been central to how I understand business. I do not implement technology for its own sake. I design measurement frameworks that expose structural risk, clarify cause-and-effect relationships, and support informed decisions. My approach is straightforward: entrepreneur to entrepreneur — direct, cost-efficient, and without unnecessary layers.
This page is intended for companies that already have analytics in place — dashboards, reports, and tools — but are no longer confident that those systems support actual decision-making. When data looks correct yet feels unconvincing, the issue is rarely the volume of data or the tools themselves. The problem is usually how measurement has been framed, structured, and interpreted.

Philosophy: Data Without Strategy Is a Risk
I view business as a strategic system. Success depends on understanding the rules, recognizing constraints, and allocating resources rationally. In digital environments, measurement is the mechanism that reveals structural strengths and weaknesses.
Traditional analytics often emphasizes traffic growth and surface-level metrics. This can obscure real performance — or underperformance — and create false confidence. Data does not explain itself. Without strategic context, metrics easily lead in the wrong direction: reports are produced but never used, or numbers are tracked that have no meaningful connection to revenue or long-term competitiveness.
Real value comes from understanding event chains, attribution logic, and the relationships between marketing, user behavior, and business outcomes. That connection is often missing.
In many projects, the turning point is not a new tool or dashboard, but the realization that previously followed metrics were misleading. Identifying that misalignment is uncomfortable, but it is usually the moment when progress becomes possible.
How I Work
- Business first. I ignore vanity metrics and focus on event chains and structural drivers that genuinely affect results.
- Efficiency matters. I rely on proven tools and established ecosystems rather than custom solutions without clear return.
- Big-picture thinking. I evaluate technical choices through a business lens — distinguishing between temporary optimizations and decisions that hold up over time.
I do not begin with dashboards or KPI lists. I begin with the decision that needs to be made and work backwards to determine what the data can realistically support — and where its limits are.
From the VIC-20 to Today
Technology has been part of my daily life since the 1980s, starting with the Commodore VIC-20 and C64. The tools have changed, but the principle remains: technology is an instrument, not the objective.
Long-term entrepreneurship and analytics require persistence. Endurance developed outside of work — on long walks and cycling in difficult conditions — mirrors the discipline required to build systems that last and to question assumptions when necessary.
My objective is clear: to focus on work that produces measurable results and to maintain the independence that entrepreneurship provides — together with my clients.
