The 80/20 Rule: EVACO’s Fastest Proof of Concept Yet

Kai Müller has spent almost eight years working with Timextender. As Head of Pre-Sales at EVACO, a German Timextender partner, Kai's role is unusual: he sells the platform to customers, then implements it himself. That combination gives him a clear view of what actually moves a data project forward, and what just slows it down.

"Timextender is doing the 80% of the stuff really quick and effortless, so people have time to care for the 20% that are left that are really important, where the difficult decisions are in there." - Kai Müller

Finding the Problem, Not Building the Solution

Before Timextender, Kai did the work manually. He points to data lineage as one of the first things that changed for him: getting a clear, fast view of where data actually comes from and where it breaks down.

"So what I really like from the beginning was the speed at which we could set up things" Kai says. In his experience, the hardest part of any data project isn't building the solution. It's finding out where the problem actually is. Timextender's metadata layer accelerates that discovery process, which Kai says is where most of the real work happens.

Why Data Quality Matters More as AI Adoption Grows

Bad data has always meant bad reports. Kai has watched that problem play out in dashboards for years. But he's seen the stakes rise as AI moves into the picture.

"Everybody knows with bad data you get bad answers from AI." - Kai Müller

As AI tools work faster, the pressure on data quality grows with them. Automating and accelerating data preparation isn't optional anymore, Kai says. It's the foundation everything else depends on.

This is where Kai sees Timextender's approach standing apart from other options on the market: a metadata layer paired with an AI-first approach. He describes the combination as unique, and particularly well suited to the small and medium-sized businesses EVACO typically works with.

Three Weeks Down to Three Days

EVACO has plenty of experience standing up data platforms on its own, which gives Kai a real baseline for comparison. Work that used to take three weeks now takes three days with Timextender.

"The best thing is when the customer has direct value from the things we build."  - Kai Müller

That's what makes the process interactive and iterative, Kai says, instead of a long wait for a finished product.

Speed isn't the only benefit Kai points to. He describes what Timextender frees up for the businesses he works with using a simple frame: the 80/20 rule. Timextender handles the repetitive 80% of the work, quickly and with little friction. That leaves people with time to focus on the 20% that's actually difficult, the decisions that require judgment, not just execution.

Proof in the Field: EMG and Beyond

That kind of speed and reliability shows up in EVACO's work. In EMG's engagement with EVACO, the manufacturing technology leader had outgrown what Qlik Sense could handle on its own, running roughly 70 BI applications for 200 users. EVACO implemented Timextender's metadata-driven modeling approach, and EMG had its first sales data flowing through the platform within two weeks, sourced from seven different IT systems. The result was a BI solution that was faster and more sustainable to develop against, with Qlik Sense running on a foundation it could scale.

Kai has shared similar results about Augustin Entsorgung, a group of waste disposal and recycling companies. A lean IT team with no dedicated developers built a proof of concept within nine weeks of kickoff, and connected more than 15 subsidiaries within six months. The project's low-code approach meant the group's Head of Controlling could lead development directly, without hiring or training new technical staff.

Whether it's a three-day proof of concept or a nine-week rollout across more than a dozen subsidiaries, the pattern holds: Timextender clears the repetitive work out of the way so people can spend their time on what's genuinely difficult.

A Partner Built for Fast Delivery

None of that happens without the partnership behind it. Kai credits Timextender's team directly for how quickly EVACO can deliver for customers, describing them as easy to reach, whether that's support, developers, or the onboarding process for new customers.

"Timextender as a partner is really great. There are so many nice people working here, so it's easy to get support, it's easy to get to talk to developers."  - Kai Müller
