Bye bye Tableau 👋 The Swedish SaaS pirates are here. Tableau is a business intelligence tool owned by Salesforce. For years it was part of how we worked at Voi. In the beginning it felt powerful, but over time it turned into what many legacy SaaS tools become: expensive, clunky and slow. Every ad hoc request ended up in an analyst backlog. Local teams across our 100 plus cities were left waiting for insights, costs kept going up and speed disappeared. So we ripped it out. The direct savings are hundreds of thousands of euros in licenses. The indirect savings are even bigger since analysts can now focus on high impact work instead of repetitive reporting. The biggest shift is speed. What once took weeks now happens in seconds. Here is how we made it possible: 1. We fixed the foundations. Years of work on data governance. Every metric has an owner, quality checks, semantics and definitions. Everyone in the company knows what a number means. With that in place, self serve became possible, which is essential when local teams in 100 plus cities need the right data at the right time. 2. We defined what we need, not what we paid for. A single source of truth, real time data streaming and self serve for non technical users. Analysts no longer spend their days on small one off requests. 3. We used LLMs as the bridge. Together with a design partner we built a UI that supports continuous business intelligence, and we created an AI data analyst that lives inside Slack and Sheets. LLMs translate natural language into SQL, query the warehouse and return insights or visuals in natural language again. This step is what unlocked true self serve at scale. But LLMs alone are not enough. In an enterprise setting you need strict guidelines and guardrails. Without governance you risk inconsistent answers, wrong definitions or even compliance issues. The combination of solid data governance with the power of LLMs is what makes this work. The results are clear: 1. Millions saved on SaaS and labor 2. One source of truth for all key metrics 3. Self serve for everyone in the company within clear constraints 4. Up to 100x faster time to insight and decision making LLMs made this shift possible. Strong governance made it safe. RIP Tableau. And it will not be the last legacy SaaS tool we replace. Long live the Swedish SaaS pirates.
