Furo’s $4M Seed: Neo + TQ Back Battery Software From Munich
Munich’s Furo raised $4 million led by TQ Ventures with Neo and Sandberg Bernthal. Deutsche Bahn is a named customer; founders left Silicon Valley to build industrial battery optimization in Germany.
Furo raised $4 million in seed financing led by TQ Ventures, with Neo, Sandberg Bernthal Venture Partners, and CDTM Venture Capital participating. TechCrunch dated the story September 10, 2026. Deutsche Bahn is a named customer. The company is a Delaware C-Corp with a Munich team; it rebranded from Lumera Energy and came through Neo’s accelerator (TechCrunch, Trending Topics).
Spine: Three founders left Apple / Google X / AI startups, moved home to Germany, and still raised a U.S.-led seed — because industrial battery economics are a European problem with American capital appetite.
Key facts
| Field | Detail |
|---|---|
| Company | Furo (furoenergy.com) — industrial battery storage software |
| Round | $4M seed (~€3.44M) |
| Lead | TQ Ventures |
| Notable | Neo, Sandberg Bernthal, CDTM VC |
| Founders | Lena Sophia Voß, Leonie Wagner, Simon Wittner (CDTM / TUM network) |
| Traction (reported) | 800+ companies; 6,000+ sites planned/optimized; Deutsche Bahn named |
| Channel | Installers, developers, manufacturers, utilities — not primarily direct end-user |
| Valuation | Not disclosed |
Who uses the product — and for what job
Users: commercial & industrial storage owners and the channel that sells/installs batteries (installers, EPCs, OEMs, utilities).
Job: forecast prices/weather, control charge/discharge, and trade unused capacity so storage pays for itself — software margin on someone else’s hardware.
Trending Topics cites up to ~40% electricity-cost reduction as a capability claim — treat as marketing, not audited savings.
Why now
- European power-price volatility made storage ROI a board-level topic.
- Founders argue proximity to German customers and cheaper senior engineering beats a forced Bay Area HQ.
- Neo already knew the team from Residency (as Lumera) — follow-on is relationship capital.
Why Neo / TQ — portfolio fit
Neo backs technical founders early; a Residency alum building energy software in Europe fits the people-first pattern. TQ Ventures led as the U.S. seed specialist chasing storage-flexibility markets. TQ Ventures, Sandberg Bernthal, and CDTM VC have no /fund/ pages here.
Competitive map
| Approach | Tradeoff |
|---|---|
| Battery OEM firmware alone | Hardware control; weak market trading |
| Utility demand-response platforms | Scale; less C&I installer channel |
| Manual Excel scheduling | Cheap; breaks at portfolio scale |
| Furo optimization layer | Asset-light; must stay trusted by installers |
What is not proven
- ARR, take rate, and verified savings vs. marketing “up to 40%.”
- How much of the 6,000 sites are paying vs. planned.
- Expansion beyond DACH without local partners.
Practical takeaway
- Founders: Sell through the installer/OEM channel if C&I is the buyer.
- Investors: Diligence site count quality and Deutsche Bahn contract depth.
- Operators: Relevant if storage ROI is being killed by dumb dispatch.
