This German Startup Just Raised $4M to Slash Your Energy Bill by 40%

Jan de Vries · 2026-09-11

Furo, a Munich-based energy software company, just closed a $4 million funding round. The goal? Make industrial battery storage actually pay off. If you've ever looked at a commercial electricity bill in Germany, you know the pain. Prices swing wildly, and most battery systems just sit there, charging and discharging on fixed schedules that ignore what's happening in the market. Furo wants to change that. ### The Problem With Batteries Today Most industrial battery installations run on rigid, pre-programmed rules. They don't care if electricity prices spike tomorrow afternoon or if a cloudy week is coming. They just follow the same pattern day after day. That's a problem, because the European power market is one of the most volatile in the world. The rapid build-out of wind and solar means prices can swing dramatically within hours. And when you're an energy-intensive factory, those swings hit your bottom line hard. According to Furo, inflexible energy demand costs industrial companies an estimated $580 billion a year worldwide. The culprit isn't renewable energy itself, but price volatility, high grid fees, load peaks, and a lack of flexibility in how power is consumed. ### How Furo's Software Works Furo's platform forecasts power prices and weather up to 48 hours ahead. Then it optimizes battery operation in real time, deciding when to charge, when to release power, and when to sell unused capacity back into the energy market. The company claims this can cut customers' electricity costs by up to 40%. That's not a small number. For a manufacturing plant with a hefty power bill, it could mean hundreds of thousands in savings. But Furo doesn't sell directly to end customers. Instead, it works through installers, project developers, storage manufacturers, and utilities. More than 800 companies already use the platform across over 6,000 sites in Germany and Europe. > "Our customers did not buy a battery in order to own a technology, but in order to lower their electricity bill. In one of the most volatile power markets in the world, that is decided by the software, not by the hardware. That is exactly why we founded Furo." — Lena Sophia Voß, co-founder of Furo ### The Team Behind the Tech Furo was founded in 2025 as Lumera Energy by Lena Sophia Voß, Leonie Wagner, and Simon Wittner. The three met during a joint master's program at the Centre for Digital Technology and Management (CDTM), a collaboration between LMU Munich and the Technical University of Munich. The funding round was led by US investor TQ Ventures, with participation from Sandberg Bernthal Venture Partners (Sheryl Sandberg's fund), Neo, and CDTM Venture Capital. Schuster Tanger, co-founding partner at TQ Ventures, said: "Lena, Leonie and Simon understand the European energy market at an extraordinary level of depth. It's a remarkable example of team-market fit. Together, they bring exceptional technical depth and operational experience in Europe's most complex power market. That's already reflected in the number of projects and the data they've built up. Coupled with a global market for storage flexibility set to multiply in the coming years, we see this as one of the greatest opportunities in Europe and beyond." ### What's Next for Furo Earlier this month, Furo announced a partnership with Berlin-based LUOX Energy, the end-customer brand of Lumenaza GmbH, to launch a combined solution for optimizing commercial and industrial battery storage systems. And in May 2026, the company rebranded from Lumera Energy to Furo. The new funding will go toward further developing the software, expanding into additional European markets, and growing the team. With AI data centers driving up energy demand and industrial companies feeling the squeeze, Furo's timing couldn't be better. If you're in the energy or manufacturing space, this is one to watch. The software layer might just be the most valuable part of the battery revolution.
