# 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](/startup/furo)** raised **$4 million** in seed financing led by **TQ Ventures**, with **[Neo](/fund/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](https://techcrunch.com/2026/09/10/furos-founders-left-silicon-valley-and-its-paying-off/), [Trending Topics](https://www.trendingtopics.eu/furo-raises-4-million-to-make-industrial-battery-storage-pay-off/)).

**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](/startup/furo) ([furoenergy.com](https://furoenergy.com)) — industrial battery storage software |
| Round | **$4M** seed (~€3.44M) |
| Lead | TQ Ventures |
| Notable | [Neo](/fund/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](/fund/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.
