Furo (formerly Lumera Energy), a Munich-based energy software company, today announced that it has closed a €3.44 million ($4 million) funding round to further develop its software, expand into additional European markets, and grow its team.
The round was led by US investor TQ Ventures, with participation from Sandberg Bernthal Venture Partners, the fund of Sheryl Sandberg, as well as Neo and CDTM Venture Capital.
“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,” said Lena Sophia Voß, co-founder of Furo.
Furo was founded in 2025 as Lumera Energy by Voß, Leonie Wagner and Simon Wittner, who met on a joint master’s programme at the Centre for Digital Technology and Management (CDTM) of LMU Munich and the Technical University of Munich.
It is a software company for the control and optimisation of commercial and industrial battery storage. The platform forecasts power prices and weather up to 48 hours ahead, optimises the operation of the storage systems in real time on that basis, and markets unused capacity in energy trading.
According to the company, global energy demand from AI data centres is rising sharply, hitting energy-intensive industrial companies hardest, especially in Germany, where electricity prices are already among the highest in the world.
It notes that battery storage provides the solution here, by storing surplus solar or wind power and releasing it when needed; the problem is that most installations have so far operated on rigid, pre-programmed rules, regardless of how the weather or electricity prices are actually developing.
Furo claims that its software works differently because it forecasts electricity prices and weather up to 48 hours ahead and decides in real time when a storage system charges and when it releases or sells power.
The company states that this enables customers to reduce their electricity costs by up to 40 per cent. It is not sold directly to end customers but rather through installers, project developers, storage manufacturers, and utilities. More than 800 companies use the platform across over 6,000 sites in Germany and Europe. The platform adapts to the respective role, from system sizing through asset operation to the marketing of free capacity in energy trading.
The German startup opines that the European and German power markets, in particular, are among the most volatile in the world, owing to the rapid build-out of wind and solar energy. Furo highlighted that its forecasting module prices in exactly these fluctuations, while static systems have so far remained blind to them.
Inflexible energy demand costs industrial companies an estimated 580 billion US dollars a year worldwide. The cause is not the build-out of renewable energy itself, but price volatility, high grid fees, load peaks and a lack of flexibility in consumption.
“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,” said Schuster Tanger, co-founding partner at TQ Ventures.
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 optimising commercial and industrial battery storage systems. In May 2026, the company announced its rebrand from Lumera Energy.
