German Stadtwerk launched a digital attacker brand in just 8 weeks, disrupting the market.

For decades, Stadtwerke Garbsen has been a trusted local utility, delivering electricity, gas, and heating while supporting its community. But as customer expectations shifted and the energy transition accelerated, standing still was no longer an option.

In 2023, the utility made a bold move: launch Purpur-Energy, a fully digital green-energy brand designed to disrupt the market. The ambition was clear— act with the speed and agility of a digital native.

With triPica’s SaaS subscription and billing platform at the core, Stadtwerke Garbsen went from concept to market in just 8 weeks. The digital backbone enabled full automation—contracting, onboarding, tariff management—freeing the team to focus on brand strategy and customer engagement.

The outcome is more than a new tariff. Purpur-Energy delivers 100% green power, transparent pricing, and digital convenience, setting a new standard for Germany’s energy market. A local utility became a digital challenger—fast, purposeful, and future-ready.
